2.45-Carat Rich Sky Blue Montana Sapphire (Heated)


A beautiful rich sky blue heated Montana sapphire, 2.45 carats.

In stock


This beautiful heated Montana sapphire is a rich sky blue color, reminding me of the “Big Sky Country” of Montana.  The sapphire was heated in Montana to develop the color and improve the clarity; the treatment is permanent and stable. There is one tiny feather in the stone but its not visible in the hand without a 10x loupe.  The high clarity of the stone makes it very bright and scintillating in the hand.

This sapphire is faceted in the classic diamond round brilliant design that has been specifically optimized for sapphire and cut to “hearts and arrows” precision.  The gem weighs 2.45 carats and measures 8.0 x 5.3 mm.  It would make an amazing center stone for a unique and one-of-a-kind engagement ring.
