Understanding Black Semi-Crystal Opal
Black Semi-Crystal Opal represents a fascinating middle ground between solid black opal and the rarer black crystal opal. The semi-crystal variety has areas of partial transparency that allow light to interact with the stone in unique ways, creating depth and dimension in the play of color. The dark web patterns in this stone add dramatic visual contrast that enhances the blue fire.
