Both citrine and amethyst are forms of quartz and owe their colors to trace amounts of iron. Dual color zones in ametrine are the result of varying oxidation states of iron within the crystal. Such oxidation states occur during the formation of the crystal when temperatures fluctuate. Ametrine is also known as trystine and bolivianite, named for Bolivia as the origin of the stone.

 

Ametrine’s Lore

Felipe de Urriola y Goitia was a member of Spain's expedition to the West. He contacted the peaceful Ayoreo tribe of Bolivia where he met Anahi, the chief's daughter and tribal princess. The princess fell in love with Felipe and the chief presented the ametrine mine as a dowry to her groom. When it was time for Felipe to return to Spain the princess chose to sail away with her husband. Her tribesmen felt abandoned and betrayed and they plotted to murder her. As she lay dying Anahi asked to see her husband one last time and presented him with this beautiful stone as a token of her eternal love. The stone's twin colors symbolize Anahi's heart torn between the love of her husband and the love of her people.

Determining Anahi Ametrine Value

The value of colored stones is typically determined by a combination of its color, clarity, cut, and carat weight. This is no different when determining what Anahi ametrine’s worth. These guidelines will help you choose apatite stones for your collection.

  • Anahi Ametrine Color

Fine ametrine shows medium dark to moderately strong orange, and vivid to strong purple or violet-ish purple. The colors of amethyst and citrine are produced by iron impurities with different oxidation states. Ametrine typically exhibits an abrupt color transition from purple to yellow; the stones with a half-and-half color split are the most popular and typically considered the most valuable.

  • Anahi Ametrine Clarity

Ametrine comes from the family of quartz. Like all quartz stones, Anahi ametrine is typically eye-clean and transparent, and exhibits a captivating vitreous luster as a finished cut and polished gem.

  • Anahi Ametrine Cut

The emerald cut displays an attractive half-and-half distribution of each color, with a sharp boundary between the two colors at the center, perpendicular to the table of the gem. This cut is preferred by Shop LC’s skilled lapidaries to show-off the bi-color effect. Ametrine gems are also often fashioned into mixed or brilliant cuts. These are cut into "blended ametrine" that has random patches of amethyst and citrine and cannot be displayed with color distinction. Ametrine is also popular in free-form or fantasy cuts.

  • Anahi Ametrine Carat

Anahi ametrine may have a finite supply but the yield often provides large carat weights. Stones of five carats and above often display intensely saturated hues.

Where Does Anahi Ametrine Come From?

The Anahi Mine in Bolivia is the top global producer of ametrine. Popular lore tells us that during the 17th century, the mine was a wedding gift to a Spanish conquistador upon marrying the princess of the Ayoreos tribe. The mine is named in her honor. Ametrine later came to Europe as gifts presented by the conquistador to the Spanish queen. After that, the mine was lost for more than three centuries. Rediscovered in the 1960s, the mine’s ametrine began appearing on the market again during the 1970s. Shop LC is proud to share this unique and beautiful gemstone with customers at affordable prices.

How is Anahi Ametrine Mined?

The Anahi mine is the only commercial source of ametrine in the world. The mining area is remote and the commute to and from the mine is done by a small airplane or by a combination of roads and boats.

The area is lined with chunks of different sizes of quartz, including outright hexagonal crystals. The hills surrounding the mine property consist of dolomitic limestone, containing veins of quartz. Several reinforced shafts and horizontal tunnels have been drilled along these veins for underground mining.

With most of the mining at Anahi done underground, there is also a small open-pit mining area. Dynamite blasting occurs once or twice per day to assist enlargement of tunnels loosening up of mineralized areas in the open pit for hand digging. The loosened rock is removed and transported up an elevator shaft and slid down a chute to another waiting mining cart in open air. The material is then dumped at a washing area where a water cannon further loosens masses of rock and mud, and a series of sieves are used to separate out particulate matter. This process then moves to presorting, where rough is hammered to separate facetable material.
