Ametrine is a unique and beautiful mineral that is a combination of two other minerals: amethyst and citrine. It is often referred to as trystine or bolivianite, and it is found in Bolivia, Brazil, and several other locations around the world. Ametrine is a variety of quartz, and its color ranges from purple to yellow, with varying degrees of each color depending on the specific specimen.One of the distinctive features of ametrine is its color zoning.

The color zoning is caused by the oxidation of iron within the crystal, which creates a boundary between the two colors. To identify ametrine, you can look for this unique color zoning as well as its characteristic hexagonal shape and hardness (7 on the Mohs scale).
