Rainbow Obsidian Rough – Small Pieces | 30–40mm

Discover the hidden beauty of these Natural Rainbow Obsidian Rough pieces, sourced in their raw, unpolished form. Measuring approximately 30–40mm—roughly the size of a South African R5 coin up to a golf ball—these striking volcanic glass specimens are perfect for collectors, lapidary artists, wire wrappers, crystal enthusiasts, and anyone who appreciates the beauty of natural minerals.

At first glance, Rainbow Obsidian often appears to be ordinary black obsidian, just as shown in the product photograph. However, its true beauty is revealed when viewed under direct sunlight or a bright light source. Depending on the individual piece and the viewing angle, subtle rainbow iridescence may become visible, while some specimens display a beautiful green to golden-yellow sheen. These optical effects are created by microscopic mineral inclusions within the volcanic glass, making every piece unique.

Because Rainbow Obsidian is a natural material, some pieces display more vibrant flashes than others, while a few may show only subtle iridescence. This variation is a natural characteristic of genuine Rainbow Obsidian and adds to the individuality of every specimen.

Ideal for tumbling, polishing, carving, cabochon cutting, display collections, or creative craft projects, these rough pieces retain their natural volcanic texture and character.
