This beautiful unheated Montana sapphire is a gorgeous blue-gray. The gem is 100 percent natural and untreated in any way. The sapphire has excellent clarity. There may be tiny inclusions that are visible with a 10x loupe that can’t be seen with the naked eye.
This sapphire is faceted in my custom “Aurora” brilliant square cushion design; the resulting gem is very bright and lively in the hand. It weighs 2.72 carats and measures 7.5 x 5.3 mm. It would make an amazing center stone for a beautiful engagement ring!
