PRECIOUS IS ALL MINE
24 carats of gold and green ametrine for $3.79 which was the lowest bid.
So what did I get?
No country of origin listed so possibly a synthetic Russian lab created stone.
The other gem I'm going for has Brazil listed as Country of Origin so that could be an amethyst heat treated for the golden part then irradiated for the purple to turn green. Amethyst and Topaz are the stones most often heat treated or irradiated.
The only place for real natural purple/gold Ametrines is the Anahi mine in Bolivia. The mine was a dowry for a conquistador named Don Luis Felipe when he married Princess Anahi from Bolivia's Ayoreos tribe in the 17th century.
The Russians have been producing synthetic (hydrothermal created) ametrines since the early 1990s. It has the same physical properties as the natural stone but any colour combination such as sky blue and golden yellow, green and yellow or orange with blue is suspect.
I'm happy as long as the colour is as depicted and the facets are sharp enough to make the bling sparkle. A lot can happen in front of a good photographer, like making a crumby stone look like a million dollars. I mean I've seen Easter Eggs that cost more than this.
