1.35-Carat Light Blue Montana Sapphire


A beautiful unheated light blue Montana sapphire, 1.35 carats.

In stock


This beautiful unheated Montana sapphire is a delicate light blue color.  In some lighting a very slight tint of green can be seen, but for the most part the dominant color is blue.  There is a tiny amount of silk and one natural crystal inclusion, but neither are visible without a loupe–its an eye clean gemstone and very brilliant in the hand.

I faceted this sapphire in a modified version of the classic diamond round brilliant design that I’ve optimized for sapphire; the result is a glittering beauty of a gemstone. The gem weighs 1.35 carats and measures 6.2 x 4.4 mm; the perfect size for an engagement ring.
