This striking 5.11 carat Oregon Sunstone is a showpiece gemstone, beautifully cut in an elongated baguette shape measuring 18.8 x 7mm. The standout feature of this stone is its rich, reflective copper schiller, which creates an almost banded appearance as light dances across its surface. Subtle flashes of blue at the edges add even more depth and intrigue, making it a visual delight from every angle.

Whether you envision it as a sleek pendant or a dramatic vertical ring, this one-of-a-kind sunstone will command attention with its bold shape and vivid play of light. Its unique size and optical effects make it ideal for a custom piece of jewelry that balances elegance and individuality.

Mined by RoseGemShop in 2019 from the renowned Dust Devil Mine near Plush, Oregon, this gem is part of a geological story millions of years in the making. Oregon Sunstone is a rare, naturally copper-bearing variety of cuprian labradorite feldspar, created by volcanic activity and found only in a small region of Eastern Oregon.

Completely natural and untreated, this sunstone showcases the unaltered beauty of the Earth—its shimmer and color a direct result of copper platelets embedded in the crystal itself.
