Size Availability Available in 10 sizes: 8g to 5/8" Black Obsidian is a naturally occurring volcanic glass formed when lava cools rapidly with minimal crystal growth. It is prized for its sleek, jet-black appearance and exceptionally smooth, glass-like texture. Appearance: A deep, uniform black with a high-gloss, reflective surface. Properties: Lightweight and glass-like; it is non-porous and finishes to a sharp, mirror-like polish. Unique Character: While primarily solid in color, some pieces may show very faint, dark grey swirls or "shadows" when held to a strong light, reflecting its volcanic origins. Note: Because these are made from natural materials, slight differences in color and pattern are to be expected, making every set one-of-a-kind.
