1.42-Carat Yellow-Green Parti-Colored Montana Sapphire (Heated)



A lovely yellow-green parti-colored heated Montana sapphire, 1.42 carats.

Out of stock


This beautiful heated Montana sapphire shows flashes of green and yellow as its held in the hand because of zones of each color–sapphires like this are referred to as “parti-colored” in the trade.  The sapphire was heated in Montana to develop the color and improve the clarity; the treatment is permanent and stable. This gem has good clarity, with just a few tiny feathers.  They are far less prominent in the hand than the macro photo implies, and do not effect the durability of the stone in any way.  I have factored them into the price, making this gem a good value for the size and color.

This sapphire is faceted in my custom “Testudo” oval brilliant design that I’ve designed and optimized for sapphire; the result is a glittering beauty of a gemstone.  The gem weighs 1.42 carats and measures 7.4 x 5.5 x 4.5 mm.  It would make an amazing center stone for a unique and one-of-a-kind engagement ring.
