Sunstones are captivating gemstones celebrated for their shimmering, sun-like appearance.
In short: Real sunstone is a feldspar with metallic-looking copper or hematite platelets that flash orange-red light from within — called aventurescence. Mohs 6-6.5 hardness, refractive index 1.525-1.548. Oregon and Indian material shows clear platelets under 10x magnification; goldstone glass imitations show uniform, repeating sparkle. Top fine 1.00ct+ Oregon stones run $50-$500 per carat.
However, with the market full of imitations, it's important to tell genuine sunstones apart from fakes.
This guide walks you through the key signs of authentic sunstones and offers insights into what makes them so special.
