Green Opal deposits in Madagascar are a relatively new find. They have a lovely apple green coloring and can include Iron dendrites (brown/reddish brown), Manganese dendrites (black), white Calcite inclusions, or small vugs (AKA ‘crystal cave inclusions’). There are a few small organic spots here and there from formations that were close to the surface as the stone was shaped and polished. ALL  inclusions/formations present are 100% natural parts of the stone.

Prices range from $2.00 to $30.00 each.  Sizes vary but can range from 1.5″ to 4.75″ in height.
