Cut: Custom cut by Doug.Oregon sunstone, also known as heliolite (from Greek helios, meaning sun, and lithos, meaning stone). Oregon Sunstones are comprised of the mineral feldspar and were formed through volcanic action. Feldspar crystals are found in several locations throughout the globe. The pink Schiller, red, bi-colored and green varieties are currently found only in Oregon.
The color appears to vary depending on both the amount and the size of individual copper particles present in the stone. A stone with Shiller is any stone that is translucent to opaque due to Schiller inclusions of copper and lead. Some of the better quality Schiller variety have an iridescent or aventurescence shimmer effect, which is caused by light reflecting from minute parallel metallic platelets suspended in the Sunstone When they are viewed in just the right direction, a metallic shimmer flashes from within the stone.
Some stones are dichroic, in that they show two different colors when viewed from different directions. Oregon sunstone is the state gemstone of Oregon.
Warm, soapy water is always a safe sunstone cleaning method. Ultrasonic and steam cleaners should be avoided.
Feldspars are rapidly attacked by hydrochloric acid, so cleaning products containing bleach should also be avoided. Internally flawless; free of inclusions.

Gemstones are cut at their correct refractive index using digital precision, this facilitates making the correct facet angles allowing the maximum amount of light to enter and reflect back up through the table. This allows optimum brilliance according to each gemstones individual refractive index.
Special care in polishing ensures that the faceted gem is showcased in all its brilliance. The introduction of precision faceting machines has revolutionized the art of gem cutting allowing the gem cutter to unveil the inner beauty of every single gemstone like it has never been done before. The cut of a gem is one of the main values of a gemstone and each gemstone requires special attention in order to unveil its potential beauty.
