AMETRINE is a combination of Amethyst and Citrine where we find the two colors purple and yellow. Its chemical formula is SiO 2 .
Amethyst and citrine belong to the silicate group. They mainly contain silicon. Their chemical formula is the same as that of quartz or agate.
Amethyst is a variety of Quartz that is purple in color due to the iron it contains. Citrine is yellow in color.
Amethyst is usually found in geodes. Those from Brazil produce large pyramidal crystals, while those from Uruguay are a deep purple.
