4.19-Carat Light Aqua Blue Montana Sapphire

A beautiful unheated aqua blue Montana sapphire, 4.19 carats.

In stock


This beautiful Montana sapphire is a lovely pale aqua blue color–a light blue-green color reminiscent of gem aquamarine.  There is a tiny remnant of a natural feather inclusion in the gem that is visible in the photo and just barely visible in the hand–otherwise the gem is exceptionally clean and bright.  Sapphires of this size are extremely uncommon in Montana.  Each year I manage get only a small handful of gems that will facet a stone larger than four carats.

I faceted this sapphire in my custom “Helena” oval brilliant design that I’ve designed and optimized for sapphire; the result is a glittering beauty of a gemstone.  The gem weighs 4.19 carats and measures 10 x 8.0 x 6.3 mm.  It would make an amazing center stone for a unique and one-of-a-kind engagement ring.
