GREEN CHRYSOBERYL. Gams Stone.
By Aamir Mannan.
Green chrysoberyl gives merely a stronger version of the broad absorption band in the blue-violet already described under yellow chrysoberyl. This is centered at 4440 A.
Weaker bands may be seen at 5050 and 4850 A. The 4440 bands may often be seen in cat's eyes forming a useful means of confirming that they are not the less highly valued quartz cat's eyes.
