A beautiful and unusual violet-blue and peach unheated Montana sapphire that changes to lilac-pink under incandescent light, 2.37 carats.

In stock


This unusual unheated Montana sapphire is a bit of a chameleon: Its both multi-colored and it changes color with the lighting.  In daylight it is a blue-gray color with flashes of pale peach.  Under fluorescent light its combination of light violet and a peachy orange color.  This is a result of the original rough having a pale orange central spot that blends in with the violet body color in the finished gem.  However, under incandescent light it changes color to a beautiful lilac pink.  There is a very light amount of natural rutile silk in this sapphire (evidence of its natural unheated status) but it has only a very minor effect on the brilliance of the gem.

This sapphire is faceted in my modified version of the diamond round brilliant cut, optimized for sapphire and cut to “hearts and arrows” level of precision; the result is a glittering beauty of a gemstone.  The gem weighs 2.37 carats and measures 8.0 x 5.2 mm.  It would make an amazing center stone for a unique and one-of-a-kind engagement ring.
