Additional Info
Citrine is a yellow to golden orange member of the quartz group. Its name is derived from a French word "citron", which means "lemon", although the color is usually more golden orange than yellow. Natural Citrine is rare, so most of the citrine on the market today is actually heat-treated amethyst or smoky quartz.
