Description

This is a remarkable sapphire for Montana–deep blue and large.  This comes from the El Dorado Bar on the Missouri River, outside of Helena, Montana.  While famous for sapphires, most are lighter blue or greenish blue.  Very few are a natural deep blue like this one, and even fewer are deep blue, large and clean enough to facet a gem.  That makes this gem special and a real rarity.  When I got this piece it looked like a greenish sapphire–until I located the c-axis of the crystal and realized it was a deep blue if oriented correctly.  I decided to cut a very deep round to follow the shape of the rough, and designed this mixed cut to achieve that goal.  The result is like a faceted drop, although it could be set in a ring by a skilled goldsmith.

While it can appear dark, in most light its a gorgeous deep denim blue color and flashes a lighter shade of blue as its moved around in the hand.  There’s a slight bit of silk near the table that cuts down the brilliance a little bit, but its not significant.  The gem is very large for a Montana sapphire at 3.90 carats and  7.47 x 7.45 mm.

Video Request

Although we do our best to take the highest quality images, sometimes it can be difficult to envision how it will look on your hand. We can take a video of up to four gems side by on the hand to help you compare them and see how they perform in daylight. Please provide the following information, and include the SKU numbers or links to the stones you would like to see a video of.

Please note that we don’t do 360-degree videos as colored gems are optimized to be viewed face up, and because the current technology is such that none of the 360-degree systems we have tested provides the accurate color.  Our desire is to present the most honest and accurate color possible!
