How Much Is Sunstone Worth?
Also known as Aventurine Feldspar
Sunstone is a feldspar with a warm, glittery shimmer ('aventurescence') created by tiny reflective platelets of copper or hematite, giving flashes of orange, gold, and red. Common Indian sunstone cabochons and tumbled stones sell for $3–$30, good cabochons and beads for $15–$80, and fine Oregon sunstone — a prized copper-bearing gem showing rich color and 'schiller,' including rare green and red-green bicolor — for $50–$1,000+ per carat as faceted gems. Value comes from the intensity and coverage of the shimmer, body color (deep red and bicolor Oregon material is top), clarity, and cut. Because plain shimmery Indian sunstone is abundant, everyday prices are low while gem-grade Oregon sunstone is a genuine collector's stone. It is sometimes confused with man-made 'goldstone,' which has a denser, artificial glitter.

What drives sunstone value
- Schiller / shimmer. Bright, full-coverage aventurescence is the key driver.
- Body color. Rich red, and rare green or red-green bicolor Oregon material, top the range.
- Clarity & cut. Eye-clean, well-faceted gems command large premiums.
- Origin. Copper-bearing Oregon sunstone far outvalues common Indian material.
Is your sunstone real?
Sunstone is natural feldspar, but is sometimes confused with (or substituted by) man-made 'goldstone' glass, which has a dense, uniform, obviously artificial copper glitter. Genuine sunstone is feldspar (Mohs 6–6.5) with an irregular, scattered natural shimmer and often visible platelet inclusions.

- Why is Oregon sunstone so much more valuable?
- Oregon sunstone is a rare copper-bearing feldspar that can be gem-clear with strong color and schiller — including scarce green and bicolor — unlike common shimmery Indian material.
- Is sunstone the same as goldstone?
- No — goldstone is man-made glass with copper flecks; natural sunstone is a feldspar with a more irregular, scattered shimmer.
