1.6" Polished, Golden Sheen Obsidian Spheres

These are polished spheres of golden sheen obsidian from Jalisco, Mexico. While pure obsidian is jet black, golden sheen obsidian appears to have a golden or silver sheen to it that changes in appearance as the stone is viewed from different angles. This interesting stone is mined from the La Revoltosa Mine near San Andreas, Jalisco, Mexico.

The spheres are approximately 1.6" wide but maybe slightly larger of smaller. The photos are representative of the sphere you will receive.

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. While pure obsidian is jet black, other impurities can give it interesting colorations and properties.

The golden sheen in golden sheen obsidian is due to tiny gas bubbles trapped in the glass. These tiny bubbles have been stretched nearly flat along the flow layers in obsidian. These tiny gas bubbles cause light to reflect in such a way as to produce the appearance of a golden or silver sheen in the obsidian.
