Please read this information about Oregon Copper Bearing Sunstone cut and
carved Stones.
Below is the grading system that used for grading finished Oregon Sunstone. Grading of Oregon
Copper Bearing Sunstone is determined by the amount of color saturation, how light or dark and color
type. It is also graded for type of Schiller, if present. Copper Schiller is a unique phenomena only
found in Oregon Copper Bearing Sunstone.
Finished Oregon Sunstone Grading System
Yellow Champagne: (yellow with green tint) to strong Yellow.
A Schiller: Visible Schiller, will have light pink or peach color tone, the crystal may also display very
light red and or green color tone(s)
AA Schiller: Bright easily visible Schiller from 2 or more angles, nice pink or peach color tone, the
crystal may also display very light red and or green color tone(s)
AAA Schiller: Strong bright flashy Schiller from 2 or more angles, strong pink or peach color tone, the
crystal may also display very light red and or green color tone(s)
A Red. Green, Bi-Color, Dichroic, Tri-Color : Light visible color tone, may be zoned and coppery. May
have minimal Schiller that does not interfere with light refraction such as speckle,
feather or bar Schiller and enhances the beauty of the stone.
AA Red, Green, Bi-Color, Dichroic Tri-Color: Medium color and saturation and some zoning, May have
minimal Schiller that does not interfere with light refraction such as speckle, feather or
bar Schiller and enhances the beauty of the stone.
AAA Red. Green, Bi-Color, Dichroic, Tri-Color: Good strong color tone, good saturation, may have
slight zoning. May have minimal Schiller that does not interfere with light refraction
such as speckle, feather or bar Schiller and enhances the beauty of the stone.
AAAA Red, Green, Bi-Color Dichroic, Tri-Color: Deep rich color and saturation throughout the stone.
May have minimal Schiller that does not interfere with light refraction such as speckle,
feather or bar Schiller and enhances the beauty of the stone.
Collector Stone: Rare intense color and exceptional beauty with or without Schiller and also stones of
large size, 10 carat and above finished stones and rough crystal 76 carat or 15 gram
and above that are a rare find by them selfs.
Grading of Oregon Sunstone is determined by the above classifications, or a combination of them.
Almost all colored crystals have some form of Schiller. Schiller is particles of suspended copper that
forms within the crystal. Copper is the main coloring agent in Oregon Sunstone, therefore colored
stone with no Schiller will receive a higher price value. Schiller makes identifying a natural untreated
cut stone or rough much easier. Copper Schiller is something like rutile in Rutilated Quartz and
creates uniqueness unmatched by any other. Schiller comes in many forms, from heavy saturated
deposits 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, snowflake or speckle (tiny dots), but all
enhance the beauty of the finished stone.
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)
Bi-Color (Dichroic)
Pigeon Blood Red, Maroon Red
Dichroic and Trichroic (Color Shift)
True Red
Green (Dichroic, color shift)
Teal (Usually a blue-green)
Blue (Rare, only a few are found annually, if any)
