This lovely unheated Montana sapphire is a gorgeous yellow-green. The gem is 100 percent natural and untreated in any way. The sapphire has excellent clarity, making it bright and scintillating in the hand. 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 modified version of the classic diamond round brilliant cut, optimized for sapphire and cut to “hearts and arrows” precision. The gem weighs 0.68 carats and measures 5.2 x 3.4 mm. It would make an amazing center stone for a unique and one-of-a-kind engagement ring.
