Citrine is the yellow to orange variety of Quartz. Natural Citrine is not common; most Citrine on the gem market is produced by heat treating Amethyst and Smoky Quartz. ... The name Citrine is derived from the citron fruit, a yellow fruit similar to the lemon. (In fact, citron means "lemon" in several languages.)
It is recognized as the official birthstone for the month of February. Amethyst belongs to the microcrystalline branch of quartz and owes its violet/purple color to iron and aluminium impurities. Without such colouring agents, amethyst would simply be transparent, ordinary colourless quartz. Like other varieties of microcrystalline quartz, amethyst has transparent to translucent clarity and a vitreous luster. Cryptocrystalline varieties of quartz almost always occur with translucent to opaque clarity.
