In stock


This lovely heated Montana sapphire is a unique combination of yellow and light blue color zones.  Depending on the lighting it can look all yellow or show flashes of blue and yellow–the effect is quite striking. The gem has outstanding clarity, appearing all but flawless through a 10x loupe.  The high clarity makes it very bright and scintillating in the hand.

This sapphire is faceted in a modified version of the classic diamond round brilliant design that is optimized for sapphire and cut to “hearts and arrows” precision; the result is a glittering beauty of a gemstone. The gem weighs 0.67 carats and measures 5.2 x 3.3 mm; the perfect size for an engagement ring.
