Emerald is the gem stone for May and is said to aid peace of mind . Part of the Beryl family. The green colour comes from traces of Chromium and/or sometimes Vanadium. Emeralds have been used as ornamentation for thousands of years. The huge Bahia Emerald is valued at $400,000,000.00. In 2017 the 18.04 Rockefeller Emerald sold for $ 5,500,000.00 million at auction.
99.9% of genuine gems have flaws. Please remember you are looking at the gems shown here at high magnification. EXPECT flaws! I do not sell man made stones. Emeralds are a type 3 gem and stones without flaws are EXTREMELY rare.
