The Fantasia® brand of Black Obsidian (also known as volcano glass) rough you are ordering is 100% natural and imported by the ton directly from Mexico to Fantasia Mining's USA rock yard. This material has a beautiful deep black color and is perfect for tumbling, polishing, cabbing, cutting, wire wrapping or keeping in it's natural form as a specimen. Your order will contain multiple pieces of this spectacular material of varying natural sizes and shapes as shown in the images which is equal to or greater than the weight purchased.

VERY IMPORTANT: This is rough natural material which means you are receiving it exactly how it came out of the ground and there may be sharp edges.
