Color grading is determined by the amount of color saturation, how light or dark and type
of color. Copper is the main coloring agent in Oregon Sunstone, therefore colored stone
with no Schiller will receive a higher price value. The following is a list of colors found in
Oregon Sunstone, from the most common to the rarest.
Yellow (Champagne, greenish-yellow)
Schiller (Pure Copper Particles within the Host Crystal)
Orange Red, Copper Red (Cinnamon)
Watermelon (Red surrounded by Green)
Pigeon Blood Red, Maroon Red
Dichroic and Trichroic (Color Shift)
Green (Dichroic, color shift)
Teal (Usually a blue-green)
Blue (Rare, only a few are found annually, if any)
Almost all colored crystals have some form of Schiller. Schiller is particles of suspended
pure copper that forms within the crystal. Copper Schiller makes identifying Oregon
Sunstone quite easy. Schiller comes in many forms, from heavy saturated deposit within a
crystal to a single wire strand. Common terms used to describe the look of this
phenomena are, plate(s), banded, barred, feather, vale, wires, speckle (tiny dots), but all
enhance the beauty of the finished stone.
