(via The Canadian Gemmologist, Vol.III, No.4, Spring, 1982) I should be called the gemstone of Ireland, except that country is not my home. I am found frequently in veins of calcite or in mica schist. I have a variable S.G; my dichroism is considered to be strong; my color is very important to my value, and my R.I is rather critical in separating me from my synthetic and imitation brothers. What am I?
Answer: Beryl, variety Emerald
