Rainbow Obsidian Tumbles – Natural Polished Stone

These rainbow obsidian tumbles are polished from natural volcanic glass and feature a smooth finish with deep black color and subtle iridescent bands that may appear in shifting light. Depending on the individual piece, the surface can reveal flashes of green, gold, purple, or bronze-toned sheen created by the internal structure of the glass. Rainbow obsidian forms when silica-rich lava cools rapidly, producing natural volcanic glass with layered visual effects and a glossy surface. The tumble shape gives each stone a rounded polished form that is easy to display, collect, gift, or use as a decorative accent. Every tumble is unique in flash, tone, shape, and surface detail, making each polished stone distinct in natural character.
