Rare Schiller Oregon Sunstone Cabochons

Oregon Sunstone Cabochons with Schiller inclusions.

These four Oregon Sunstone Cabochons are beautifully polished and ready to become part of your collection. Each one shows rich peach to red color with attractive eye visible Schiller phenomenon (copper platelets).

Schiller Effect:

Oregon Sunstone is a unique labradorite sub-group of the abundant feldspar mineral. Feldspar can be found in several parts of the world in yellow and transparent colors. Only the Oregon Sunstone exhibits the tiny copper platelets formed inside the stone which create a luminous metallic effect within the stone called “Schiller.” These copper mineral inclusions are usually arranged parallel to the direction of perfect cleavage in the feldspar crystal, so the glittering reflection is only seen when looking at the cleavage surface.

Choices:

1. Red/Orange: 9 x 7mm Pear Shape 1.81 carats
2. Peach: 13 x 9mm Pear Shape  4.23 carats
3. Peach: 14 x 10mm Oval Shape  5.92 carats

At The Sunstone Store our all time favorite gem is the Oregon Sunstone, in part because of its amazing array of naturally occurring colors from reds to greens, champagnes, and the unique copper included “schillers.”

The Feldspar group of minerals are one of the most common on the planet, however Oregon’s unique copper-bearing Plagioclase Feldspar is found nowhere else in the world. The Oregon Sunstone was designated Oregon’s Official State Gem by the Oregon legislature in 1987.
