Yellow-Green Precision cut Cushion 5.4 x 4.6mm/0.72ct Montana Sapphire Loose Gemstone

1 item left

This custom precision-cut untreated Montana Sapphire is available for a custom-built ring by Nodeform Jewelry. This one-of-a-kind gemstone is a gorgeous stunner.

The genuine untreated Montana sapphire has a gorgeous yellow-green color. It is a very lively stone with excellent cutting. The faceted Sapphire is about ~0.72 carat. It measures 5.4 x 4.6 x 3.4 mm. It was faceted 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.  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.

    This stone would look great set sideways in Nodeform's signature FOLD semi-bezel ring setting available here.  Other custom designs are possible. Just contact me to discuss.

    Due to the unusual cut of this gemstone, it does not fit into many of our other ring settings without some design modifications. Please allow extra design and fabrication time to provide a perfect fit.
