DETAIL: There are ancient references to ametrine from Persian, Roman, and Greek sources. Anecdotal evidence seems to suggest an ancient source of ametrine in India, and indeed ametrine was (re)discovered recently in the Indian state of Andhra Pradesh near Hyderabad, an ancient city which was a trading center on the camel caravan route which crossed to Persia and Europe on one side, and China and Russia to the other side. There is also evidence of a medieval source of ametrine in Scotland, perhaps in the general vicinity of the Devonian lava beds in Angus, Scotland. However ametrine first became famous in the modern world in the seventeenth century when a Spanish conquistador received it as a dowry when he married a South American Indian princess. Ametrine was subsequently introduced to Europe through the conquistador's gifts to the Spanish queen. This is a very large, very clean, 19th century faceted baguette cut ametrine from the Anahi Mine in Bolivia. Imported for use in indigenous jewelry, the gemstone was hand crafted and faceted by a 19th century Russian artisan, part of an heritage renown for the production of the elaborate gemstones and jewelry of the Czars of Medieval, Renaissance, and Victorian Russia. Ametrine is actually very rare in nature, having both the manganese traces which produce amethyst's purple, as well as the iron traces which produce citrine's yellow. The crystals must then be exposed to a variable source of heat, such as might be the case when a crystal partly encased in rock is exposed on one surface to sun shine. Slowly a portion of the gemstone will change color from amethyst's purple to citrine's yellow. This occurs rather rarely in nature. It seems that the ancient Mediterranean world knew of ametrine. The ancient source for ametrine was likely India via camel caravan through Persia. With the ancient source of ametrine lost and forgotten, ametrine was (re)introduced to Renaissance Europe as "trystine" from a Bolivian source in the seventeenth century. It was considered a very rare gemstone and was extremely expensive in Victorian Europe. Natural ametrine remains rather rare. Today most modern ametrine is either synthetic or induced by irradiating or heat-treating amethyst. This particular specimen is a very nicely colored semi-precious gemstone, with a sharp delineation between the yellow and purple. As you can see from the photo enlargements here, it is to the eye completely transparent and free from inclusions, and possesses exceptional sparkle and luster. It is very clean, water clear, and very bright. The trained eye will easily discern from the photo that the gemstone has been hand-faceted. The coarseness of the 19th century faceting is considered appealing to most gemstone collectors, and is not considered a detriment. Unlike today's computer controlled machine processes, the cut and finish of a gemstone such as this is the legacy of an artisan who lived two centuries ago. Such antique hand-faceted gemstones possess much greater character and appeal than today's mass-produced machine-faceted gemstones. This gemstone has great luster and sparkle, and to the eye is completely transparent, but it is not absolutely flawless. True, any blemishes it possesses are not visible to the naked eye, and even at 500% as in these photo enlargements here (or under a 5x jeweler's loupe) there are no discernible flaws. However we hesitate to use the word "flawless", as sooner or later blemishes will show up at higher levels of magnification with almost every natural gemstone. An absolutely flawless gemstone is very rare in nature (and usually turns out to be synthetic). However the gemstone can be characterized at a minimum, to use trade jargon, as "loupe clean". To the eye it is indeed flawless; even to a jeweler's loupe it is clean. Close examination with a jeweler's loupe will however reveal occasional slight irregularities in the faceting and finish. Naturally these characteristics are not only expected of hand-finished gemstones, you must also consider that two centuries ago the mining techniques prevalent did not allow the ultra deep mining operations which are so common today. Keep in mind that two centuries ago mankind was more or less limited to surface deposits or near surface deposits of gemstones. Higher quality gemstones which today are routinely mined from beneath hundreds of meters, even kilometers beneath the earth's surface, were simply inaccessible then. For these reasons antique gemstones must be appreciated as antiques first, gemstones second. The relatively superlative quality of contemporary gemstones routinely mined from deep beneath the earth's surface today were simply not accessible two centuries ago, or at least, only rarely so. However for most, the unique nature and character of antique gemstones such as this more than makes up for minute blemishes which by and large, are (if at all) only visible under high magnification. AMETRINE HISTORY: The Anahi Mine in Bolivia is the world’s primary source of ametrine (sometimes referred to as “trystine” or “bolivianite”). The mine first became famous in the seventeenth century when a seventeenth-century Spanish conquistador received an ametrine gemstone as a dowry when he married a princess from the local Ayoreos tribe named Anahi. Ametrine was introduced to Europe through the conquistador's gifts to the Spanish Queen. Small deposits of Ametrine were discovered both in Brazil and Canada during the twentieth century. There is evidence of a medieval source of ametrine in Scotland, perhaps in the general vicinity of the Devonian lava beds in Angus, Scotland. There are also ancient references to ametrine from Persian, Roman, and Greek sources. Anecdotal evidence seems to suggest an ancient source of ametrine in India, and indeed ametrine was (re)discovered recently in the Indian state of Andhra Pradesh near Hyderabad, an ancient city which was a trading center on the camel caravan route which crossed to Persia and Europe on one side, and China and Russia to the other side. variety of quartz, and is of course closely related to both amethyst and citrine (ame-trine). Throughout the history of the ancient world, gemstones were believed capable of curing illness, possessed of valuable metaphysical properties, and to provide protection. Found in Egypt dated 1500 B. C., the "Papyrus Ebers" offered one of most complete therapeutic manuscripts containing prescriptions using gemstones and minerals. Gemstones were not only valued for their medicinal and protective properties, but also for educational and spiritual enhancement. Though there appear to be ancient records indicating familiarity with ametrine, no records exist indicating what properties the ancients may have perceived imbued into ametrine. However a clue to what properties the ancients may have believed ametrine possessed, might be found in contemporary folklore. Ametrine is a Due to its dual color, ametrine is considered to be a talisman that balances the opposing forces of nature and bridges the divide between the material and the spiritual world. The purple amethyst part of the stone helps one to visualize the future he seeks, while the yellow citrine color pushes one towards making this goal a reality. The dual nature of ametrine is said to bring spirit and mind into harmony, catalyzing a profound flow of new ideas and insights. Current alternative practitioners believe that ametrine aids the wearer in overcoming bad habits, addictions and addictive traits, including over-eating and substance abuse. Perhaps behaviorally related, ametrine is also said to be useful in combating self-esteem problems, ridding the wearer’s “aura” of negative energy. Ametrine is also believed to be of use in soothing, calming and balancing the emotions, helping the wearer maintain a rational outlook under pressure, while at the same time promoting mental clarity, creativity, energy, determination and endurance, and so it is said it is best to keep an ametrine talisman near your desk or your computer (where it can best assist you while you work). Present-day medical uses espoused by alternative practitioners include ametrine’s usefulness in stimulating oxygenation of the body, a process which is believed to have a strong cleansing effect on the metabolism and tissues. Ametrine is also believed to be beneficial for those suffering from headaches, backaches, and disorders related to the pancreas.

We travel to Russia each year seeking antique gemstones and jewelry from one of the globe’s most prolific gemstone producing and cutting centers, the area between Chelyabinsk and Yekaterinburg, Russia. From all corners of Siberia, as well as from India, Ceylon, Burma and Siam, gemstones have for centuries gone to Yekaterinburg where they have been cut and incorporated into the fabulous jewelry for which the Czars and the royal families of Europe were famous for. My wife grew up and received a university education in the Southern Urals of Russia, just a few hours away from the mountains of Siberia, where alexandrite, diamond, emerald, sapphire, chrysoberyl, topaz, demantoid garnet, and many other rare and precious gemstones are produced. Though perhaps difficult to find in the USA, antique gemstones are commonly unmounted from old, broken settings – the gold reused – the gemstones recut and reset. Before these gorgeous antique gemstones are recut, we try to acquire the best of them in their original, antique, hand-finished state – most of them centuries old. We believe that the work created by these long-gone master artisans is worth protecting and preserving rather than destroying this heritage of antique gemstones by recutting the original work out of existence. That by preserving their work, in a sense, we are preserving their lives and the legacy they left for modern times. Far better to appreciate their craft than to destroy it with modern cutting. Not everyone agrees – fully 95% or more of the antique gemstones which come into these marketplaces are recut, and the heritage of the past lost. But if you agree with us that the past is worth protecting, and that past lives and the produce of those lives still matters today, consider buying an antique, hand cut, natural gemstone rather than one of the mass-produced machine cut (often synthetic or “lab produced”) gemstones which dominate the market today. Our interest in the fabulous history of Russian gemstones and the fabulous jewelry of the Czar’s led to further education and contacts in India, Ceylon, and Siam, other ancient centers of gemstone production and finishing. We have a number of “helpers” (family members, friends, and colleagues) in Russia and in India who act as eyes and ears for us year-round, and in reciprocity we donate a portion of our revenues to support educational institutions in Russia and India. Occasionally while in Russia, India, Siam, and Ceylon we will also find such good buys on unique contemporary gemstones and jewelry that we will purchase a few pieces to offer to our customers here in America. These are always offered clearly labeled as contemporary, and not antiques – just to avoid confusion. We can set most any antique gemstone you purchase from us in your choice of styles and metals ranging from rings to pendants to earrings and bracelets; in sterling silver, 14kt solid gold, and 14kt gold fill. When you purchase from us, you can count on quick shipping and careful, secure packaging. We would be happy to provide you with a certificate/guarantee of authenticity for any item you purchase from us. There is a $2 fee for mailing under separate cover.
