Citrine is a transparent, yellow variety of Quartz, ranging in color from pale to golden yellow, honey or almost brown, and may contain rainbow or sparkle inclusions..
The name comes from the French word citron, meaning lemon. It was used as a gem in Ancient Greece as far back as 300 B.C., and because of its color, is sometimes mistakenly referred to as Gold Topaz, Madeira or Spanish Topaz, or Safranite.
