Notes - To get this quality in a rare, step-cut of this authentic gem primarily mined out by high end jewelers in the 1970's is impossible. One of the most faked gems on the market. We are a USA based company and have our rough batch 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. Vaulted since 1973 and cut in 2019, Van Cleef & Arpels (among other high end jewelers,) wiped out the pocket of this rare gem by 1980. This rough had been vaulted since 1973. TOP quality exceeding the quality of the majority of the 1970's pieces.
