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 around 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 its state gemstone.
*CARE (Oregon Sunstone)*
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.
*CLARITY CHART*
IF – Internally flawless; free of inclusions
VVS – Very, very slight inclusions; microscopic inclusions are barely seen under a loupe with 10x magnification
VS – Very Slight inclusions; visible inclusions that can be seen under magnification and sometimes also with the unaided eye.
SI – Small inclusions; inclusions that are obvious under magnification and to the unaided eye.
I – Heavy or large inclusions obvious to the naked eye
I work exclusively with a precision machine when faceting gemstones. This allows extra brilliance and appeals only seen in precision cut gems. 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 gemstone’s 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 as 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. If you’re looking for that extra special stone, I hope you find it here. Sincerely, Doug

Why are users outbidding themselves?
When a bid is placed, this is the maximum amount a user is willing to bid for the product. Our system will then automatically bid on that users behalf, incrementally increasing the bid to maintain their position as the highest bidder, up to the specified maximum.
When there is an icon indicating 'Auto Bid,' it means our system is actively placing bids for the user based on their maximum bid. This may appear as if users are outbidding themselves, but it's simply a result of the system updating the bid to reflect the users maximum limit.
