Okay – what exactly is a Dichroic Copper-Bearing Oregon Sunstone with Schiller Effect?

This is one of the rarest and most sought-after gemstones for collectors and it’s only mined from one small region in the United States.  There are a lot of Sunstones mined throughout the world but nothing can compare to the Oregon Sunstone with the Schiller effect.  Oregon Sunstone is a trade name for a particular type of Labradorite, which belongs to the mineral family of feldspars. Like common sunstone, it comes in various colors, including red, blue, green, yellow and most commonly, a faint straw color. Unlike the common sunstone, Oregon Sunstone is transparent, and can be cut into amazingly lively faceted gems.  Also, Oregon Copper-Bearing Sunstone is a lot harder than other Sunstones mined elsewhere.  They are comparable to Amethyst and Citrine, 7.2 on the Mohs' Scale.

An oddity of Oregon Sunstone is the enhancing presence of ‘Schiller’. In the case of Oregon Sunstone, Schiller consists of very thin, opaque, parallel sheets (flat crystals) of copper within the gemstone. These sheets are so thin that they cannot be seen from the edge. When viewed from an angle perpendicular to the Schiller plane, the Schiller acts like a polished copper mirror, reflecting the coppery color back to your eyes. Many stones appear to be perfectly transparent at first, but when they are viewed in just the right direction, a pink to red metallic shimmer flashes from within the stone.

A Schillered Oregon Sunstone is more valuable than any other Sunstone. A properly cut Oregon Sunstone with Schiller maintains brilliance from every viewing angle, but displays a fascinating color shifting effect as the copper Schiller is rotated into view. There also is a phenomena in some gemstones which makes them ‘dichroic’, meaning they show two different colors when viewed from different directions (these are most valuable).

Oregon mined gems are rarest of ALL Sunstones in the world.  Only the genuine Oregon Sunstones are found in extremely rare colors like pure Blood Red, Padparadscha, Orange, Salmon and Copper Red, and even the most valued Green or Blue Green, many of them sparkle with illusive pure Copper Schiller. 

Colored Gemstones are graded and valued by several factors:             

1. Rarity             

2. Color             

3. Clarity             

4. Size             

5. Cut

This gemstone is the top quality in every way.
