Information about Sheen Obsidian

Sheen obsidian is a volcanic glass that exhibits a metallic or iridescent sheen when light reflects off its surface.

This effect is caused by microscopic gas bubbles or mineral inclusions trapped during the cooling of molten lava. It is typically black or dark brown with a golden, silver, or bronze-like shimmer that becomes visible under direct lighting.

The sheen appears in layers or patches, giving the stone a striking visual effect.

Uses and History

Sheen Obsidian is primarily used for jewellery usage and in decorative objects. The decorative objects are often spheres, pyramids, and other ‘new age’ shapes and objects. The material is also often sold tumbled.

Obsidian has been used since prehistoric times for making weapons, tools, and ceremonial items – whether ‘sheen’ Obsidian was ever used specifically I’m afraid I couldn’t find any verifiable information.

Hazards and Warnings

Can be extremely sharp, and caution should be taken with the dust if this material is worked.

Mineral collectors should wash their hands after handling specimens, to avoid any exposure to potential toxins.

Almost all rocks, minerals (and, frankly, almost all other substances on earth) can produce toxic dust when cutting, which can cause serious respiratory conditions including silicosis.

When cutting or polishing rocks, minerals, shells, etc, all work should be done wet to minimise the dust, and a suitable respirator or extraction system should be used.
