Worlds Largest Trilliant Ametrine 322 carats

Wow, it’s a beauty! Three hundred and twenty two carat ametrine from Bolivia. Cut to mix the violet and gold color instead of the usual color split down the middle, this unique gem was cut by Steve Moriarty. 90 hours was required to finish this extraordinary gem. Originally cut for donation to the Field Museum. When we were informed they had the right to sell donations we decided we would sell it. The style is called a tri-polar. High clarity in a most unique multicolor gem. 44mm x 44mm x 37mm deep.
