1.01-Carat Light Green Montana Sapphire


A lovely light green unheated Montana sapphire in my custom “Testudo” oval design, 1.01 carats.

Out of stock


This lovely unheated Montana sapphire is a beautiful light green to yellow-green color.  This particular sapphire has some minor natural inclusions visible in the macro image, but they are not visible in the hand without a 10x loupe; its an eye clean gemstone and very bright and flashy in the hand.  I have factored these inclusions into the pricing for this gem, making it a great value for the size.

This sapphire is faceted in a custom brilliant oval design that I created just for Montana sapphire. I’ve named the design “Testudo” as the facet pattern of the crown reminds me of a tortoise’s shell.  The gem weighs 1.01 carats and measures 6.4 x 4.9 x 4.1 mm.  It would make the perfect gem for a unique engagement ring!
