Ametrine
Ametrine has a fascinating origin and formation process. It is believed to form in a specific type of quartz crystal known as amethystine quartz, which occurs in certain regions where amethyst and citrine overlap. The most well-known and significant source of ametrine is the Anahi Mine in Bolivia.
Amethyst forms in cavities or voids within rocks when silicon dioxide (SiO2)-rich fluids containing traces of iron and other impurities are exposed to specific temperature and pressure conditions. These conditions result in the growth of quartz crystals with a purple coloration due to the presence of iron impurities.
Citrine, on the other hand, is formed when amethyst undergoes heat treatment. Natural amethyst crystals exposed to high temperatures, such as those found in volcanic environments or subjected to geological processes like contact metamorphism, can transform into citrine. The heat causes the iron impurities to change their oxidation state, resulting in the vibrant yellow to orange hues characteristic of citrine.
Ametrine is formed when these two processes overlap. It occurs when amethyst and citrine crystals grow together in the same rock or cavity. This unique phenomenon is attributed to temperature variations and fluctuations in the iron content during crystal formation. As a result, ametrine displays distinct zones or sections with varying shades of purple and yellow or orange.
