The name consists of the Greek words χρυσός (chrysos) = golden and βήρυλλος (berylos) = beryl, which describe the color of the mineral.
Despite the similarity of names - chrysoberyl and beryl, they are two completely different gems, although both contain beryllium. Chrysoberyl is the third hardest, frequently occurring natural gem and lies at 8.5 on the Mohs mineral hardness scale, between corundum (9) and topaz (8). Ordinary chrysoberyl is yellowish green and transparent to translucent. If the mineral has a good light green to yellow color and is transparent, it is used as a gem.
