2.9ct AAA bicolor Oregon Sunstone

This Oregon Sunstone may be small at only .9ct and 7x5mm, but just look at this color! Beautiful AAA Red with a hint of dark green. The rough for this stone comes from the world famous Dust Devil mine in the Rabbit basin of Oregon's rugged Outback. There is an internal fracture you can see in the photos. It should not compromise the integrity of the stone, but I've discounted it significantly because of this. It's practically impossible to see this fracture without magnification. This stone would be great for a dainty ring or as part of a larger piece for a little color pop.

This stone originated at the Sunstone Butte mine. This higher elevation mine (about 15 miles from the Sunstone Collection area) has an abundance of darker colored greens and bicolor Oregon Sunstones. This one is cut in a rectangle with concave cuts on the sides to give it extra refraction. Photos just don't do this stone justice. The stone weighs 3.85ct and measures 7.8x12mm.

Oregon Sunstone, the always natural and untreated state gem is a rare feldspar containing copper, which gives it not only a wide range of colors, but also the aventurescent quality called "schiller" from thousands of microscopic bits of copper inside the stone. Usually, these crystals get only as large as 60-70cts before being cut. Often, bigger crystals have fractures, which makes cutting large stones over 10cts difficult. This stone, however, is not the norm. It weighs a massive 22.9ct and measures 23x17mm. It's the largest stone in my inventory. Just being large isn't the only thing that makes this stone special, though. The tri-color green, pink, and gold or "mystique" color is one of the rarest for Oregon Sunstone. Watch the colors shift and move as the stone turns. The concave cutting on this gem also ads to the brilliance, giving it a radient shine. It is truly a one of a kind masterpiece.
