This top quality rough Ethiopian opal has an orangish base with beautiful intense colors that flow within. This gorgeous piece has a large surface area of the opal that makes it a piece that will display very well. Not only that, but this piece is very fine cutting material that will have a great yield. We recommend that this opal material NOT be submerged in water (unless it is being cut, water will keep it cool), and it should never have any oils applied to it.Also, due to the hydrophane nature of this opal, the weight can vary slightly with humidity. We consider this to be a Thumbnail (TN) sized specimen.
