Yellow-Green Cushion Montana Sapphire Fold Solitaire Engagement Ring

1 item left

One-of-a-kind engagement ring with a genuine untreated yellow-green Montana sapphire set in a semi-bezel setting.The unique sapphire was cut by Jeffrey Hapeman from rough from the Rock Creek deposits in the mountains of Philipsburg, Montana.

Your ring will be custom made with the sapphire shown laid into the sample mounting. Your ring will be made in your metal of choice to fit this very special and unique gemstone. The ring will be carved out of wax, cast in precious metal, hand set and hand finished.

The genuine un-treated Montana sapphire has a gorgeous yellow-green color. Its a very lively stone with excellent cutting. The faceted Sapphire is about ~0.72 carat, and measures 5.4 x 4.6 x 3.4 mm. Jeffrey faceted it in a custom oval/cushion brilliant design to best utilize the natural shape of the gem rough.

The color is an interesting mix as the gem had a golden yellow center and a blue-green rim.  In most lighting it shows as a medium yellow-green.  Under fluorescent lighting, the color shifts to a more greenish yellow and in daylight it can appear yellow to greenish-yellow depending on the angle its viewed from.  Very unique!  The gem is completely natural and unheated and has outstanding brilliance with just a bit of glow from the silk.The silk you can see here in the photos is not visible in the hand and is proof that the gem has not been heated.
