Welo Black Ethiopian Opal Mineral Specimen fluorescent This piece is pictured underThis beautiful Welo black Ethiopian opal specimen has an amazing color play within its dark base color. The face of the opal is a large area that is filled with fire. It appears that the opal only has a thin coating of the host rock that covers this piece and is almost all opal. This is a natural Welo black Ethiopian Opal with no treatments. We consider this piece to be a Miniature Mineral Specimen (MIN). This beautiful mineral specimen is available
