About Cymophane
Formula:
BeAl2O4
Name:
From the Greek words meaning 'wave' and 'appearance', in reference to the haziness that visually distorts what would normally be viewed as a well-defined surface of a cabochon.
An opalescent variety of chrysoberyl. Exhibits a bluish (or yellowish according to other sources) chatoyancy which is caused by microscopic tube-like cavities or needle-like inclusions of rutile in an orientation parallel to the c-axis.
