DETAIL: 
You can think of Ametrine as a gemstone quality quartz crystal which when growing up could not decide whether it wanted to be an Amethyst or a Citrine, and so developed a “split personality”.  This is a very large, very clean, handcrafted baguette cut ametrine semi-precious gemstone from the Anahi Mine in Bolivia.  Exported to Russia for use in indigenous jewelry, the gemstone was hand crafted and faceted by a Russian artisan into this somewhat coarse briolette, an old fashioned cut reflecting a centuries-long 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 as you can also see from the photo enlargements completely transparent and free from blemishes, and possesses exceptional sparkle and luster.  It is very clean, water clear, and very bright.

The gemstone was hand cut into a sparkling, brilliant, briolette cut gemstone with lots of flash and depth.  Under magnification the gemstone shows the unmistakable characteristics of having been hand crafted.  The coarseness of the handcrafted finish is considered appealing to most gemstone collectors, and is not considered a detriment, or to detract from the value of a gemstone.  Of course these characteristics are not only expected of hand-finished gemstones, most serious collectors consider such gemstones more desirable, possessed of greater character and uniqueness when compared to today's cookie-cutter mass-produced machine-faceted gemstones.  Unlike today’s computer controlled machine produced gemstones that approach flawlessness in a perfect finish, the cut and finish of a handcrafted gemstone such as this is the cultural legacy passed onwards by artisans who lived centuries ago.

The pendant setting is of contemporary origin.  It is a high quality setting constructed of sterling silver.  If preferred, we do have the ability to re-set the stone in 14kt solid gold.  Included is a free silver electroplate chain in your choice of lengths between 16 and 24 inches.  A wide variety of other chains are available upon request in sizes from 16 to 30 inches, and in metals ranging from gold and silver electroplate to sterling silver and solid 14kt gold as well as a bronze-toned copper chain.  The default chain (absent contrary instructions) is silver electroplate, 24 inches.  This gemstone has great luster and sparkle, and to the eye is completely transparent, but one cannot say with absolute certainty that it is absolutely flawless.  True, any blemishes it possesses are not visible to the naked eye, and even at 600% 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 "eye 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 expected of hand-finished gemstones.  However for most, the unique nature and character of hand-crafted gemstones such as this more than makes up for imperfect finishes which by and large, are only noticed 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.

Ametrine is a 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.

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.
