This remarkable unheated Montana sapphire is a very pale yellow color–so light it can appear colorless in some lighting.  It is exceptionally clean for an unheated sapphire, and incredibly bright and scintillating.

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 1.33 carats and measures 6.5 x 4.2 mm.  It would make an amazing center stone for a unique and one-of-a-kind engagement ring.
