SKU: MS4371 Categories: , ,


This lovely heated Montana sapphire is a gorgeous deep blue-green. The color was developed by heating the gem in Montana, but no other treatments were made to the gem. The treatment is permanent and stable and not only develops the color, but also improves the clarity. There is a 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. There may be tiny inclusions that are visible only with a 10x loupe.

This gem is faceted in our “Helena” brilliant oval design, created and optimized for sapphires; the result is a glittering beauty of a gemstone. The gem weighs 2.88 carats and measures 9.0 mm x 7.7 mm.
