This incredible heated Montana sapphire is gorgeous rich teal color–one of the finest colors found in the Montana gems and my personal favorite.  There are some tiny internal feather inclusions visible in the macro image, but they are not visible in the hand without a 10x loupe–it’s eye clean. The gem has incredible natural clarity and combined with the cutting it makes for an incredibly brilliant and scintillating gem in the hand. I have factored the feathers into the price, making this an excellent value for the size, color and rarity.

This sapphire is faceted in a modified version of the classic diamond round brilliant design that is optimized for sapphire and cut to “hearts and arrows” precision; the result is a glittering beauty of a gemstone. The gem weighs 4.17 carats and measures 9.5 x 6.2 mm; the perfect size for an engagement ring.  Only a handful of sapphires are mined in Montana each year that are large enough to facet a gem of this size, making this a real rarity.
