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.
