Bicolor concave cut 3.85ct Oregon Sunstone

This stone looks a lot like a very expensive sunset tourmaline, but it's not. It's a bi-color Oregon Sunstone with shades of pink and gold. The concave cutting ads an extra dimension to this gorgeous gemstone that glistens and gleams with warm tones. This stone would look stunning, set in rose gold, yellow, or white gold. The choice is all yours. This stone measures 12.5mm across and weighs 5.75ct. Good sized stone for a ring or a pendant.

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.

This bright red and gold bi-color Oregon Sunstone has some brilliant color to it. It shows some dazzling "schiller," the name for the tiny bits of copper inside the stone that catch the sun and shine so beautifully. The color is mostly red with hints of orange and gold. As with most Oregon Sunstone, it will change depending upon the light and viewing angle. The stone weighs 6.8ct and measures 17x11mm, making it the perfect size for a pendant or brooch.
