Nice Mahogany Gold Sheen Obsidian is getting hard to find..... It is from the Black Rock Desert in western Utah where it was geologically deposited approximately 2.5 million years ago (the late Tertiary Period), during volcanic eruptions in the Black Spring area of the Black Rock Desert area in western Utah. A certain amount of water always is present in obsidian. Very small inclusions of water vapor in the form of bubbles often are trapped in the glass. Tiny gas bubbles that have been stretched nearly flat along the flow layers in obsidian generally cause the reflectance of gold sheen and silver sheen obsidian.
Note: Thermal fractures are a common occurrence with most rock. We do our best to be accurate in the description of materials, noting any visible fractures or flaws. If for some reason you are not happy with your purchase, please contact us and we will make it right.
