833-557: A dispute with Fabergé Inc. over trademark rights in the use of the name 'Fabergé' for jewellery. Fabergé & Cie continued to operate in Paris until 2001. The reputation of Fabergé as a producer of the highest standard was maintained by publications and major exhibitions, such as those at the Victoria & Albert Museum in 1994 and the Royal Collection in 2003–4. Following the end of

952-399: A dominant red body color. This is generally caused by traces of chromium (Cr ) substituting for the (Al ) ion in the corundum structure. The color can be modified by both iron and trapped hole color centers. Unlike localized ("intra-atomic") absorption of light, which causes color for chromium and vanadium impurities, blue color in sapphires comes from intervalence charge transfer, which is

1071-516: A friend bribed guards, Agathon did not succeed in making his escape from the USSR until November 1927 when he, his wife Maria and son Oleg, together with four helpers, escaped by sleigh under cover of darkness across the frozen Gulf of Finland.

1428-410: A lot of strain due to the high thermal gradient between the flame and surrounding air. To release this strain, the now finger-shaped crystal will be tapped with a chisel to split it into two halves. Due to the vertical layered growth of the crystal and the curved upper growth surface (which starts from a drop), the crystals will display curved growth lines following the top surface of the boule. This

1547-602: A mining co-operative of local villagers owning 15% and Mazengia Demma owning the remaining 10%. The company holds a 200-square-kilometre emerald exploration license in southern Ethiopia. Exploration activity began in June 2015 in an area to the north of the licence, called the Dogogo Block.

1785-400: A rate of 1 to 100 mm per hour. The alumina crystallizes on the end, creating long carrot-shaped boules of large size up to 200 kg in mass. Synthetic sapphire is also produced industrially from agglomerated aluminum oxide, sintered and fused (such as by hot isostatic pressing ) in an inert atmosphere, yielding a transparent but slightly porous polycrystalline product. In 2003,

1904-523: A related trust on the one hand, Renova Group , Vekselberg and Vladimir Kutnetsov met in court in the Cayman Islands over the original acquisition of the Fabergé brand name from Unilever. The claim of Vekselberg to get damages from Gilbertson (he made no claim over rights to the trademark) was dismissed in court. The judge called the lawsuit a personal fight between Gilbertson and Vekselberg. Vekselberg appealed

2023-503: A respected laboratory such as GIA , Lotus Gemology , or SSEF , is often required by buyers before they will make a purchase. Sapphires in colors other than blue are called "fancy" sapphires. "Parti sapphire" is used for multicolor stones with zoning of different colors (hues), but not different shades. Fancy sapphires are found in yellow, orange, green, brown, purple, violet, and practically any other hue. Gemstone color can be described in terms of hue , saturation , and tone . Hue

2142-467: A special designation for gemstone auction participants who build a track record of winning lots at its auctions. These companies are termed "Gemfields Authorised Auction Partners" and enter into bilateral agreements with Gemfields in relation to that status. Such companies can then use the associated branding & identity in promotional and sales materials. Gemfields owns the Kagem emerald mine in Zambia which

2261-417: A variety of shades. Corundum that contains extremely low levels of chromophores is near colorless. Completely colorless corundum generally does not exist in nature. If trace amounts of iron are present, a very pale yellow to green color may be seen. However, if both titanium and iron impurities are present together, and in the correct valence states, the result is a blue color. Intervalence charge transfer

2380-442: Is a process that produces a strong colored appearance at a low percentage of impurity. While at least 1% chromium must be present in corundum before the deep red ruby color is seen, sapphire blue is apparent with the presence of only 0.01% of titanium and iron. Colorless sapphires, which are uncommon in nature, were once used as diamond substitutes in jewelry, and are presently used as accent stones. The most complete description of

2499-459: Is a specific change in energy for the electron, and electromagnetic energy is absorbed. The wavelength of the energy absorbed corresponds to yellow light. When this light is subtracted from incident white light, the complementary color blue results. Sometimes when atomic spacing is different in different directions, there is resulting blue-green dichroism . Purple sapphires contain trace amounts of chromium and iron plus titanium and come in

2618-486: Is a type of sapphire that exhibits a star-like phenomenon known as asterism ; red stones are known as "star rubies". Star sapphires contain intersecting needle-like inclusions following the underlying crystal structure that causes the appearance of a six-rayed "star"-shaped pattern when viewed with a single overhead light source. The inclusion is often the mineral rutile , a mineral composed primarily of titanium dioxide . The stones are cut en cabochon , typically with

2737-439: Is added to the flame, causing it to burn slightly hotter. This expands the growing crystal laterally. At the same time, the pedestal is lowered at the same rate that the crystal grows vertically. The alumina in the flame is slowly deposited, creating a teardrop shaped " boule " of sapphire material. This step is continued until the desired size is reached, the flame is shut off and the crystal cools. The now elongated crystal contains

2856-489: Is called padparadscha . Significant sapphire deposits are found in Australia , Afghanistan , Cambodia , Cameroon , China ( Shandong ), Colombia , Ethiopia , India Jammu and Kashmir ( Padder , Kishtwar ), Kenya , Laos , Madagascar , Malawi , Mozambique , Myanmar ( Burma ), Nigeria , Rwanda , Sri Lanka , Tanzania , Thailand , United States ( Montana ) and Vietnam . Sapphire and rubies are often found in

2975-451: Is common practice to heat natural sapphires to improve or enhance their appearance. This is done by heating the sapphires in furnaces to temperatures between 800 and 1,800 °C (1,470 and 3,270 °F) for several hours, or even weeks at a time. Different atmospheres may be used. Upon heating, the stone becomes bluer in color, but loses some of the rutile inclusions (silk). When high temperatures (1400 °C+) are used, exsolved rutile silk

3094-428: Is commonly understood as the " color " of the gemstone. Saturation refers to the vividness or brightness of the hue, and tone is the lightness to darkness of the hue. Blue sapphire exists in various mixtures of its primary (blue) and secondary hues, various tonal levels (shades) and at various levels of saturation (vividness). Blue sapphires are evaluated based upon the purity of their blue hue. Violet and green are

3213-548: Is derived from the Latin word sapphirus , itself from the Greek word sappheiros ( σάπφειρος ), which referred to lapis lazuli . It is typically blue, but natural "fancy" sapphires also occur in yellow, purple, orange, and green colors; "parti sapphires" show two or more colors. Red corundum stones also occur, but are called rubies rather than sapphires. Pink-colored corundum may be classified either as ruby or sapphire depending on

3332-409: Is dissolved and it becomes clear under magnification. The titanium from the rutile enters solid solution and thus creates with iron the blue color. The inclusions in natural stones are easily seen with a jeweler's loupe . Evidence of sapphire and other gemstones being subjected to heating goes back at least to Roman times. Un-heated natural stones are somewhat rare and will often be sold accompanied by

3451-564: Is enamelled on gold to represent a normal hen's egg. This pulls apart to reveal a gold yolk, which in turn opens to produce a gold chicken that also opens to reveal a replica of the Imperial Crown from which a miniature ruby egg was suspended. Although the Crown and the miniature egg have been lost, the rest of the Hen Egg as it is known is now in the collection of Victor Vekselberg . The tradition of

3570-554: Is heavily tilted to the red end of the spectrum, thus tipping the balance to red. Color-change sapphires colored by the Cr + Fe/Ti chromophores generally change from blue or violet-blue to violet or purple. Those colored by the V chromophore can show a more pronounced change, moving from blue-green to purple. Certain synthetic color-change sapphires have a similar color change to the natural gemstone alexandrite and they are sometimes marketed as "alexandrium" or "synthetic alexandrite". However,

3689-432: Is in contrast to natural corundum crystals, which feature angular growth lines expanding from a single point and following the planar crystal faces. Chemical dopants can be added to create artificial versions of the ruby, and all the other natural colors of sapphire, and in addition, other colors never seen in geological samples. Artificial sapphire material is identical to natural sapphire, except it can be made without

Large rubies of note found in the Montepuez deposit are the Rhino Ruby (40.23 carats), and the Eyes of the Dragon (45 carats). Montepuez residents have accused private security contractors employed by the Montepuez Ruby Mine of perpetrating acts of violence against local community members. The allegations include robberies, shootings of illegal miners, arson of local homes to clear area for mining, and in one case, burying an illegal miner alive. In February 2020,

4046-416: Is required of any mode of enhancement that has a significant effect on the gem's value. There are several ways of treating sapphire. Heat-treatment in a reducing or oxidizing atmosphere (but without the use of any other added impurities) is commonly used to improve the color of sapphires, and this process is sometimes known as "heating only" in the gem trade. In contrast, however, heat treatment combined with

From 1964 to 1984, under the direction of Barrie, many well-known and successful product lines (as well as feature movies) were launched by Fabergé Inc. Barrie supervised

6426-571: The Soviet Union and the rise of the oligarchs, Russian collectors sought to repatriate many of Fabergé's works, and auction prices reached record highs. On 27 November 2007, the Rothschild Fabergé Egg was auctioned at Christie's in London for £8.98 million. The Rothschild Fabergé egg became the record price for a piece of Fabergé, as well as the highest price ever paid for a Russian object and

6545-603: The Spanish Trading Corporation (which imported soap and olive oil ), closed his company because of the Spanish Civil War and established a new enterprise to manufacture perfumes and toiletries. Rubin registered his new firm in 1937 as Fabergé Inc. , at Hammer's suggestion. In 1943, Rubin registered the Fabergé trademark for perfume in the United States. In 1945, the Fabergé family discovered that their name

6664-635: The Tsar giving his Empress a surprise Easter egg by Carl Fabergé continued. From 1887, it appears that Carl Fabergé was given complete freedom as to the design of the Imperial Easter eggs as they became more elaborate. According to the Fabergé Family tradition, not even the Tsar knew what egg form they would take: the only stipulation was that each one should contain a surprise. The House of Fabergé completed 50 Imperial eggs for Alexander III to present to his Empress and for Nicholas II to present to his mother,

6783-683: The area of Franklin, North Carolina . The sapphire deposits of Kashmir are well known in the gem industry, although their peak production took place in a relatively short period at the end of the nineteenth and early twentieth centuries. These deposits are located in the Paddar Valley of the Jammu region of Jammu and Kashmir in India. They have a superior vivid blue hue, coupled with a mysterious and almost sleepy quality, described by some gem enthusiasts as ‘blue velvet”. Kashmir-origin contributes meaningfully to

6902-588: The biggest problem the Yogo mine faced was not competition from heated sapphires, but the fact that the Yogo stones could never produce quantities of sapphire above one carat after faceting. As a result, it has remained a niche product, with a market that largely exists in the US. Lattice ('bulk') diffusion treatments are used to add impurities to the sapphire to enhance color. This process was originally developed and patented by Linde Air division of Union Carbide and involved diffusing titanium into synthetic sapphire to even out

7021-415: The blue color. It was later applied to natural sapphire. Today, titanium diffusion often uses a synthetic colorless sapphire base. The color layer created by titanium diffusion is extremely thin (less than 0.5 mm). Thus repolishing can and does produce slight to significant loss of color. Chromium diffusion has been attempted, but was abandoned due to the slow diffusion rates of chromium in corundum. In

7140-466: The body color, visibility, and intensity of the asterism. The color of the stone has more impact on the value than the visibility of the star. Since more transparent stones tend to have better colors, the most expensive star stones are semi-transparent "glass body" stones with vivid colors. On 28 July 2021, the world's largest cluster of star sapphires, weighing 510 kg (1,120 lb), was unearthed from Ratnapura, Sri Lanka. This star sapphire cluster

7378-433: The cause of the blue color. Verneuil patented the process of producing synthetic blue sapphire in 1911. The key to the process is that the alumina powder does not melt as it falls through the flame. Instead it forms a sinter cone on the pedestal. When the tip of that cone reaches the hottest part of the flame, the tip melts. Thus the crystal growth is started from a tiny point, ensuring minimal strain. Next, more oxygen

7497-1272: The causes of color in corundum extant can be found in Chapter ;4 of Ruby & Sapphire: A Gemologist's Guide (chapter authored by John Emmett, Emily Dubinsky and Richard Hughes). Sapphires are mined from alluvial deposits or from primary underground workings. Commercial mining locations for sapphire and ruby include (but are not limited to) the following countries: Afghanistan , Australia , Myanmar / Burma , Cambodia , China , Colombia , India , Kenya , Laos , Madagascar , Malawi , Nepal , Nigeria , Pakistan , Sri Lanka , Tajikistan , Tanzania , Thailand , United States, and Vietnam . Sapphires from different geographic locations may have different appearances or chemical-impurity concentrations, and tend to contain different types of microscopic inclusions. Because of this, sapphires can be divided into three broad categories: classic metamorphic, non-classic metamorphic or magmatic, and classic magmatic. Sapphires from certain locations, or of certain categories, may be more commercially appealing than others, particularly classic metamorphic sapphires from Kashmir, Burma, or Sri Lanka that have not been subjected to heat-treatment. The Logan sapphire ,

7616-459: The center of the star near the top of the dome. Occasionally, twelve-rayed stars are found, typically because two different sets of inclusions are found within the same stone, such as a combination of fine needles of rutile with small platelets of hematite ; the first results in a whitish star and the second results in a golden-colored star. During crystallization, the two types of inclusions become preferentially oriented in different directions within

7735-600: The collection. The value of the collection is 2 million US dollars. In 2009, a Fabergé museum was opened by Alexander Ivanov in Baden-Baden , formerly a spa destination for 19th-century Russian aristocrats. It houses a very large collection of some 1,500 items including the Karelian Birch egg, made exclusively in 1917 for Tsar Nicholas II of Russia . The museum also owns one of the Constellation eggs , which Ivanov claims

7854-409: The color penetration is far greater than with titanium diffusion. In some cases, it may penetrate the entire stone. Beryllium-diffused orange sapphires may be difficult to detect, requiring advanced chemical analysis by gemological labs ( e.g. , Gübelin, SSEF , GIA , American Gemological Laboratories (AGL), Lotus Gemology . According to United States Federal Trade Commission guidelines, disclosure

8568-470: The crystal, thereby forming two six-rayed stars that are superimposed upon each other to form a twelve-rayed star. Misshapen stars or 12-rayed stars may also form as a result of twinning . The inclusions can alternatively produce a cat's eye effect if the girdle plane of the cabochon is oriented parallel to the crystal's c-axis rather than perpendicular to it. To get a cat's eye, the planes of exsolved inclusions must be extremely uniform and tightly packed. If

8687-685: The deliberate addition of certain specific impurities (e.g. beryllium, titanium, iron, chromium or nickel, which are absorbed into the crystal structure of the sapphire) is also commonly performed, and this process can be known as "diffusion" in the gem trade. However, despite what the terms "heating only" and "diffusion" might suggest, both of these categories of treatment actually involve diffusion processes. The most complete description of corundum treatments extant can be found in Chapter 6 of Ruby & Sapphire: A Gemologist's Guide (chapter authored by John Emmett, Richard Hughes and Troy R. Douthit). In 1902,

8806-448: The dome is oriented in between these two directions, an off-center star will be visible, offset away from the high point of the dome.

In early October, Carl Fabergé left Petrograd on the last diplomatic train for Riga . The revolution in Latvia started in

9044-470: The first to have been made by a Fabergé reunited with the family since 1917. In November 2011, Fabergé items were being sold in the Fine Jewellery Room at Harrods in London's Knightsbridge, and later in the month, Fabergé opened its own boutique on Grafton Street in the heart of London's Mayfair area. In May 2012, Fabergé opened its own boutique on New York's Madison Avenue. In 2012, Gilbertson and

9163-537: The flaws that are found in natural stones. The disadvantage of the Verneuil process is that the grown crystals have high internal strains. Many methods of manufacturing sapphire today are variations of the Czochralski process , which was invented in 1916 by Polish chemist Jan Czochralski . In this process, a tiny sapphire seed crystal is dipped into a crucible made of the precious metal iridium or molybdenum , containing molten alumina, and then slowly withdrawn upward at

9282-487: The galleries of Europe's leading museums. He was also apprenticed by the jeweler Josef Friedman of Frankfurt-am-Main . Carl returned to Saint Petersburg in 1864 and entered his father's firm.

9401-436: The highest premium, although Burma, Sri Lanka, and Madagascar also produce large quantities of fine quality gems. The cost of natural sapphires varies depending on their color, clarity, size, cut , and overall quality. Sapphires that are completely untreated are worth far more than those that have been treated. Geographical origin also has a major impact on price. For most gems of one carat or more, an independent report from

9520-573: The introduction of the Brut toiletry line for Fabergé, which was promoted by football player Joe Namath . In 1977, he signed Farrah Fawcett to a promotional contract with Fabergé for the Farrah Fawcett hair product and fragrance lines.

In 1967, actor and businessman Cary Grant

9639-471: The joint venture fund. In 2004, Vekselberg had purchased the largest Fabergé collection in existence from the Forbes family (for 50 million pounds) shortly before it was to be sold at auction, leaving him with the largest Fabergé jewellery collection but not with the Fabergé brand name. On 3 January 2007, Pallinghurst Resources (now Gemfields ), an investment advisory firm based in London and of which Gilbertson

9758-418: The joint venture negotiated to buy the Fabergé brand name from Unilever. Vekselberg (a collector of Fabergé Imperial eggs who owns nine of the jewel-encrusted creations, having acquired the Forbes family collection in 2004 for a reported US$ 100 million) insisted that one of his personal companies (as opposed to the joint venture) get title to the brand, although the benefits of reviving the brand would stay within

9877-666: The largest faceted gem-quality blue sapphires in existence. Particolored sapphires (or bi-color sapphires) are those stones that exhibit two or more colors within a single stone. The desirability of particolored or bi-color sapphires is usually judged based on the zoning or location of their colors, the colors' saturation, and the contrast of their colors. Australia is the largest source of particolored sapphires; they are not commonly used in mainstream jewelry and remain relatively unknown. Particolored sapphires cannot be created synthetically and only occur naturally. Pink sapphires occur in shades from light to dark pink, and deepen in color as

9996-411: The latter term is a misnomer: synthetic color-change sapphires are, technically, not synthetic alexandrites but rather alexandrite simulants . This is because genuine alexandrite is a variety of chrysoberyl : not sapphire, but an entirely different mineral from corundum. Large rubies and sapphires of poor transparency are frequently used with suspect appraisals that vastly overstate their value. This

10115-675: The locale. Commonly, natural sapphires are cut and polished into gemstones and worn in jewelry . They also may be created synthetically in laboratories for industrial or decorative purposes in large crystal boules . Because of the remarkable hardness of sapphires – 9 on the Mohs scale (the third-hardest mineral, after diamond at 10 and moissanite at 9.5) – sapphires are also used in some non-ornamental applications, such as infrared optical components, high-durability windows , wristwatch crystals and movement bearings, and very thin electronic wafers , which are used as

The Bolsheviks imprisoned his sons Agathon and Alexander . Initially, Agathon was released to value the treasures seized from the imperial family, the aristocrats, wealthy merchants and Fabergé, amongst other jewellers. He was again imprisoned when the Bolsheviks found it difficult to sell this treasure at Agathon's valuations. With Europe awash with Russian jewels, prices had fallen. Madame Fabergé and her eldest son, Eugène, avoided capture by escaping under

10472-406: The most common secondary hues found in blue sapphires. The highest prices are paid for gems that are pure blue and of vivid saturation. Gems that are of lower saturation, or are too dark or too light in tone are of less value. However, color preferences are a personal taste. The 423-carat (84.6 g) Logan sapphire in the National Museum of Natural History , in Washington, D.C. , is one of

10591-432: The most expensive price for a timepiece. Many celebrities and billionaires collect Fabergé pieces; Joan Rivers ' estate sold $ 2.2 million worth of Fabergé items at an auction. During the course of business ventures in communist Russia during the 1920s, American oil tycoon Armand Hammer acquired many objects made by the original House of Fabergé, including Fabergé eggs. In 1937, Hammer's friend Samuel Rubin , owner of

10710-624: The name Fabergé became synonymous with the ultimate in luxury when the Forbes family's Fabergé collection became widely publicised in the mid 1980s. In 1989, the German jewelry manufacture company Victor Mayer was given the exclusive licensing rights to produce heirloom quality Fabergé Eggs, jewellery and watches in 18 carat gold and platinum with gem stones, vitreous enamel and diamonds. In collaboration with Fabergé expert Géza von Habsburg new designs for eggs and jewellery were marketed worldwide. The first contemporary Fabergé jewellery and egg collection

10829-457: The name's final e may have been an attempt to give the name a more explicitly French character to appeal to the Russian nobility's Francophilia . French was the official language of Russia's royal court , it was widely used by the country's aristocracy , and Russia's upper classes associated France with luxury goods . Later that year, Gustav married Charlotte Jungstedt, the daughter of Carl Jungstedt, an artist of Danish origin. In 1846,

In the United States, a minimum color saturation must be met to be called a ruby , otherwise the stone is referred to as a pink sapphire . Padparadscha is a delicate, light to medium toned, pink-orange to orange-pink hued corundum , originally found in Sri Lanka , but also found in deposits in Vietnam and parts of East Africa . Padparadscha sapphires are rare;

11186-517: The rarest of all is the totally natural variety, with no sign of artificial treatment. The name is derived from the Sanskrit padma ranga (padma = lotus; ranga = color), a color akin to the lotus flower ( Nelumbo nucifera ). Among the fancy (non-blue) sapphires, natural padparadscha fetch the highest prices. Since 2001, more sapphires of this color have appeared on the market as a result of artificial lattice diffusion of beryllium. A star sapphire

11305-458: The same geographical settings, but they generally have different geological formations. For example, both ruby and sapphire are found in Myanmar's Mogok Stone Tract, but the rubies form in marble, while the sapphire forms in granitic pegmatites or corundum syenites. Every sapphire mine produces a wide range of quality, and origin is not a guarantee of quality. For sapphire, Jammu and Kashmir receives

11424-524: The second half of the 18th century, a Jean Favri (subsequently Favry) is known to have been employed as a tobacco planter. By 1800, an artisan called Pierre Favry (later Peter Fabrier) had settled in Pärnu, in the Baltic province of Livonia (now Estonia ). A Gustav Fabrier was born there in 1814.

12019-412: The transfer of an electron from one transition-metal ion to another via the conduction or valence band . The iron can take the form Fe or Fe , while titanium generally takes the form Ti . If Fe and Ti ions are substituted for Al , localized areas of charge imbalance are created. An electron transfer from Fe and Ti can cause a change in the valence state of both. Because of the valence change, there

12138-583: The types of items that their father retailed years before. To distinguish their pieces from those made in Russia before the Revolution, they used the trademark FABERGÉ, PARIS, whereas the Russian company's trademark was just FABERGÉ.

12495-445: The visible spectrum. This is an absorption band in the yellow (~590 nm), along with valleys of transmission in the blue-green and red. Thus the color one sees depends on the spectral composition of the light source. Daylight is relatively balanced in its spectral power distribution (SPD) and since the human eye is most sensitive to green light, the balance is tipped to the green side. However incandescent light (including candle light)

12733-416: The year 2000, beryllium diffused "padparadscha" colored sapphires entered the market. Typically beryllium is diffused into a sapphire under very high heat, just below the melting point of the sapphire.
