2" Polished Golden Sheen Obsidian Spheres

These are beautiful, 2" diameter polished spheres of golden sheen obsidian from the La Revoltosa Mine near San Andrés, Jalisco, Mexico.

While typical obsidian has a deep, glassy black appearance, golden sheen obsidian displays a striking metallic luster that shimmers in shades of gold and silver. This captivating optical effect is caused by countless microscopic gas bubbles trapped within the volcanic glass, which reflect light and create a luminous sheen that shifts as the sphere is viewed from different angles.

The photos are representative of the spheres you will receive, but do not show the exact piece. Each sphere is unique, with natural variations in its golden sheen, patterns, and coloration.

Obsidian is a natural volcanic "glass" that is formed when molten rock cools so quickly that the atoms don't have enough time to arrange themselves into crystals. To form obsidian, the composition of the lava must be high in silica. Depending on the minerals present within this lava along with the cooling rate, a variety of colorful bands, spots, or swirls can appear once the lava has solidified. Pure obsidian is often a solid black color, but impurities can result in small color variations throughout.

The golden sheen in golden sheen obsidian is caused by tiny gas bubbles trapped in the glass. These tiny bubbles have been stretched nearly flat along the flow layers, causing light to reflect in such a way as to produce that characteristic golden or silver sheen in the obsidian.
