Madagascar Green Dendritic Opal 6mm Round - 15-16 Inch 50mm with some transparent inclusionsThis variety of opal is named "dendritic" for the small inclusions within it that resemble moss or ferns.

Opals are hydrated amorphous forms of silica, created when silica hardens within the fissures of other stones.
