Cut from gorgeous ametrine, these Cabochons are a blend of amethyst and citrine. They are flat backed with rounded tops and range in size from approximately 9.5x23mm to 13x33mm. This listing is for one randomly selected cabochon.
Ametrine, also known as trystine or by its trade name as bolivianite, is a mixture of amethyst (purple) and citrine (yellow/orange). The colour of the zones visible within ametrine are due to differing oxidation states of iron within the stone. 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.
