ZIRCON

Zircon has been known under various names since antiquity. The current name for zircon most likely comes from the Persian word zargun meaning "golden colored." Another potential namesake is the Arabic word zarkun, meaning "cinnabar" or "vermillion," possibly a result of zircon's colors.
The first known reference to this sparkling stone as zircon was in an ancient Hindu poem about the Kalpa tree, described as a glowing tree draped with gemstones, with leaves made of zircons. It is referred to in the Bible under various other names, including the jacinth (red zircon) that is set in the breastplate of Aaron and as the stone given to Moses in Ezekiel. Zircon is also among the "foundation stones" of Jerusalem's city walls in Revelations. Ancient gem lovers knew zircon as hyacinth, a name that is sometimes used to refer to the stone even today
