Sharpe Crystals is an Albany, NY–based mineral business founded by Billy Sharpe, a University at Albany student with a passion for geology and hands-on collecting. We specialize in responsibly sourced mineral specimens, including Herkimer diamonds, calcite, and willemite—many of which are mined by us directly.Our approach is rooted in science and education. We prioritize accurate identification, clear sourcing, and honest presentation over trends or claims. Every piece we offer reflects a respect for geology and the natural processes that create these minerals.
