Notes - To get this quality rare step-cut of this authentic gem primarily mined out by high end jewelers in the 1970's is rare. One of the most faked gems on the market. We are a USA based company and have our rough bath tested by GIA for any treatment and authenticity of the gems we produce. This is one of our finest step cut cabs. This apple green material rivals the finest jadeite and Van Cleef & Arpels among other high end jewelers wiped out the discovery of this rare gem by 1980. This rough had been vaulted since 1973. TOP quality exceeding many of the 1970's pieces.
