Chrysoberyl


Chrysoberyl gemstone is an aluminate of beryllium. Meaning of Chrysoberyl means ‘A gold white spar.’ Although there is similarity of the names, chrysoberyl and beryl, but they are two compeletly different gemstone. Chrysoberyl is the third hardest natural gemstone and llies between corundum and topaz on the hardness of scale.

Three main varieties of chrysoberyl. Ordinary yellow chrysoberyl, cat's eye or cymophane, and alexandrite. Although yellow chrysoberyl was referred to as chrysolite during the Victorian and Edwardian eras, that name is no longer used in the gemological nomenclature.


Ordinary chrysoberyl is a yellowish-green, transparent to translucent chrysoberyl and has often been referred to in the literature as chrysolite due to the common olive color of many of its gems, but that name is no longer used in the gemological nomenclature. When the mineral exhibits good pale green to yellow color and is transparent, then it is used as a gemstone.
