Out of stock


This beautiful unheated Madagascar sapphire is gorgeous steely blue.  This sapphire is completely 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 are difficult or impossible to see with the naked eye at a normal viewing distance, and it has a slightly silky quality due to rutile silk.

This sapphire is faceted in a custom brilliant oval design, optimized for sapphire and cut to high precision. The gem weighs 3.41 carats and measures 10.4 x 7.6 x 5.4 mm.  It would make an amazing center stone for a unique and one-of-a-kind engagement ring.
