Opal (var: Opal-AN) / (var: Hyalite Opal) (“Blood Vessel Opal”) Willard Wulff This is a special pieceWow, I was impressed when I saw this piece as the sheer aesthetics are almost unheard of for the material. Typically, its impossible for these Hyalites to form in such a pleasing three dimensional shape, but this piece breaks the mold. Not only is it incredibly showy, but it has a wide range of colors starting with a fiery orange red hue on one end which grades across the specimen into nearly colorless pale golden color and is actually opaque WHITE at
