Obsidian Rough

Obsidian comes in many types. Rainbow and color sheens produce unusual cabochons and knapped items. The color is the result of light play in the flow layers of the volcanic glass.

Although obsidian has a reputation of being difficult to polish, we have found that if the stone is ground through successively finer grits and the stone isn't heated too much during the polishing stage, that a high polish can be obtained with cerium oxide, or diamond. Mohs hardness 5 to 5.5.
Back in Stock!! Spiderweb Obsidian Rough - $8.50/pound
Locality: Chihuahua, Mexico Spiderweb Obsidian was recently discovered in Chihuahua, Mexico. A small amount of rough was mined before it played out. Therefore, this beautiful material will no longer be available. We were very lucky to be able to obtain some of the last rough that the mine produced and are pleased to be able to offer it for sale.
