Description

This beautiful heated Montana sapphire is a rarity–a color-change sapphire.  In daylight and some fluorescent lights it appears a steely blue-green color, with faint hints of purple, while under incandescent light, it changes to a pale gray-lavender color.  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.  This gem has excellent clarity, with just one tiny inclusion that is not visible without a 10x loupe.  Its very brilliant in the hand!

This sapphire is faceted in my modified version of the classic diamond round brilliant cut, optimized for sapphire and cut to “hearts and arrows” precision.  The gem weighs 1.10 carats and measures 6.1 x 4.0 mm.  It would make an amazing center stone for a unique and one-of-a-kind engagement ring.

Video Request

Although we do our best to take the highest quality images, sometimes it can be difficult to envision how it will look on your hand. We can take a video of up to four gems side by on the hand to help you compare them and see how they perform in daylight. Please provide the following information, and include the SKU numbers or links to the stones you would like to see a video of.

Please note that we don’t do 360-degree videos as colored gems are optimized to be viewed face up, and because the current technology is such that none of the 360-degree systems we have tested provides the accurate color.  Our desire is to present the most honest and accurate color possible!
