Hold a nugget of Oregon sunstone in your palm, and you will understand why the 1987 Oregon legislature designated it as the official state gemstone.  Sunstone is a variety of a mineral called oligoclase.  Uncommon in its composition, clarity, and colors, it is a large, brightly colored transparent gem in the feldspar family.  Inclusions of hematite and copper give the mineral a golden shimmer.  In Oregon, sunstone occurs in the south, central portion of the state near the California border.

Some Oregon sunstones exhibit a glow from within due to millions of microscopic copper platelets, known as schiller. Colors of the stone vary from clear, champagne, yellow, light pink, salmon, orange, and red to blue-green. Intense red and blue-green are the colors that are most rare. Sometimes, when viewed from different angles, as many as three colors will show within one stone. Sunstone is 6.5-7.2 on the Moh's hardness scale, which means it can be polished, faceted, and carved and made into jewelry.

Sunstone is mined from shallow pits in Lake and Harney counties, where it formed in lava flows millions of years ago. Native Americans valued sunstone nuggets, trading them across western America and using them in Medicine Wheel ceremonies. Sunstone has been found in burial sites and sacred bundles.



What Causes The Color In Oregon Sunstone?

Sunstone occurs in a range of colors that begin with colorless and ranges through to yellow, orange and red. The color is determined by the abundance and size of the copper platelets within the gemstone. The copper platelets impart a green, pink or reddish color to the stone. Some exceptional stones can show more than one color. It can start off pink and on the other side of the stone be bolder and strengthen in color which could be orange. 

Sunstone is an amazing specimen. It is translucent to transparent Feldspar that produces bright metallic flashes when light interacts with tiny plate-like mineral inclusions within the stone. When light enters the stone it reflects a flash of light in the eye of the observer who views the gemstone at the correct angle. This is also known as aventurescence.

Pink can either be the stone base color or be produced by a haze of schiller. The orange color shades go from orange-yellow to orange-red which is described as copper or copper red. Another color is ‘root beer’ which is the deep reddish brown, slightly orange to almost pure red to even slightly blue
