Fireworks 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 and tin oxides, or diamond.
Mohs hardness 5 to 5.5.
