Ametrine (Quartz Variety); light purple & yellow; 3ct 10x8mm, emerald cut


Ametrine, also known as Tristine 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.

The color of the zones visible within ametrine are due to differing oxidation states of iron within the crystal. The citrine segments have oxidized iron while the amethyst segments are unoxidized. The different oxidation states occur due to there being a temperature gradient across the crystal during its formation. Artificial ametrine is grown with the hydrothermal method using solutions doped with specific elements, followed by irradiation of the created crystals.
