Dendritic Opal Ring
India
The seepage of iron oxides and other impurities into the silica which comprises common opal can produce some surprisingly beautiful branching "fernlike" or dendritic patterns as seen in the present ring. The oval cabochon of white opal with black dendrites, measuring 33.0 x 27.0mm, is bezel-set in silver, size 9.
