1.00-Carat Colorless Montana Sapphire

1.00-Carat Colorless Montana Sapphire


A beautiful colorless unheated sapphire from Montana, 1.00 carats.

In stock


This beautiful unheated sapphire is colorless, quite rare for the Montana gems.  The gem has very good clarity, with just a slight amount of natural rutile silk present and a few tiny inclusions, only visible with a 10x loupe.  The high clarity gives the gem excellent brilliance, it’s quite bright and flashy in the hand, much more so than the photo would imply.

This sapphire is faceted in the classic diamond round brilliant design, optimized for sapphire and cut to “hearts and arrows” precision.  It weighs 1.00 carats and measures 6.2 x 3.7 mm.  It would make an amazing center stone for a beautiful engagement ring!
