1.15ct Unheated Green Montana Sapphire, Trillion
1.15ct Pastel Green to Greenish Blue Montana Sapphire, Unheated
Custom Trillion design and cut by Craig Oliveira
6.35 x 6.35 x 4.1 mm
An unstoppably clean and sparkly Montana Sapphire Trillion, mined from the alluvial gravels of the Missouri River outside Helena, Montana. Incredible crystal, a frosty cool green outdoors shifts to a delicate light blue or titanium gray indoors. The world-class cutting on this rare American gem make it dance with the slightest movement! My personal pick so far for this mining season.
