SKU: MS1310 Categories: , ,


This beautiful unheated Montana sapphire is a lovely aqua blue. It is 100 percent natural and untreated in any way. This sapphire has excellent clarity, making it bright and scintillating in the hand. There may be tiny inclusions that are visible only with a 10x loupe. There is a very slight haze to the gem from undissolved rutile silk, but it gives the gem a soft glow that is quite pleasing and enhances the color in low light. The inclusions and haze have been factored into the price, making this a great value for the size and color. 

This sapphire is faceted in our custom “Testudo” brilliant oval design, created and optimized for sapphire. The result is a glittering beauty of a gemstone. The gem weighs 1.30 carats and measures 6.9 x 5.3 x 4.4 mm, the perfect size for an engagement ring!
