  I love the way the purple and yellow intermingle in this interesting gemstone.

 

Ametrine, also known as trystine or by its trade name as bolivianite, is a naturally occurring variety of quartz. It is a mixture of amethyst and citrine with zones of purple and yellow or orange. Almost all commercially available ametrine is mined in Bolivia, although there are deposits being exploited in Brazil and India.

 

The color of the zones visible within ametrine are due to differing oxidation states of iron within the crystal. The different oxidation states occur due to there being a temperature gradient across the crystal during its formation.

 

Artificial Ametrine can be created by differential heat treatment of amethyst

Legend has it that ametrine was first introduced to Europe by a conquistador's gifts to the Spanish Queen, after he received the Anahi mine in Bolivia as a dowry.

I think Ametrine is very cool and I am happy with the strand I found at the recent Gem and Jewelry show. 

Enjoy!
