Madagascar Dendiritc Green Opal 10mm Round A Grade - 15-16 Inch Hackamite creating fascinating patternsThis variety of opal is named "dendritic" for the small inclusions within it that resemble moss or ferns. These inclusions consist of iron, manganese and other metallic oxides captured during the forming of the rock.
