Chrysoberyl is transparent to translucent and sometimes chatoyant. An interesting feature of uncut crystals of chyrsoberyl are the cyclic twins called trillings. These twinned crystals have a hexagonal appearance, but are the result of a triplet of twins with each "twin" taking up 120 degrees of the cyclic trilling. The word chrysoberyl is derived from the Greek chrysos, "golden," and beryllos, of uncertain etymology. 1 Occurrence 2 Alexandrite variety 3 Cymophane variety 4 See also 5 References 6 External links Chrysoberyl occurs in granitic rocks, pegmatites and mica schists; often it is found in alluvial deposits.
