Welo Ethiopian hydrophane opal mineral specimen with an amazing play of color. This opal material should NOT be submerged in water or have any oils applied to it ever. 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.
Locality: Welo Ethiopia
Measurement: 22mm x 18mm x 13mm
