Leopard Skin Rhyolite Slab – Orbicular Pattern with a Wild Side This Leopard Skin Rhyolite slab features the iconic orbicular patterns and mottled colors that have made this material a lapidary favorite for decades. Resembling the rosettes of a leopard’s coat, the oolitic orbs are embedded in a solid rhyolite matrix from a now-depleted volcanic source. 📏 Measurements (inches – longest – approx.): 6.4 x 2.3 x 0.28 This piece has excellent surface coverage and structure, making it ideal for cutting into high-impact cabochons or displaying as-is. Depending on the exact makeup, Leopard Skin Rhyolite can take a polish that ranges from matte to mirror, and this old stock material continues to get harder to find in quality form.
