What exactly is a Copper-Bearing Oregon Sunstone with 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. 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.

In the case of Oregon Sunstone, Schiller consists of very thin, opaque, parallel sheets (flat crystals) of copper within the gemstone. 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.
