Peruvian Blue Opal Pendant - 1.068"

Andean blue opal is a translucent form of the gemstone, often infused with dark brown or black dendritic crystals across its surface. Like other opals, the gemstone forms from silica-rich water filtering through porous sandstone, depositing the mineral to be heated and pressurized into the beautiful gem.  This pendant contains a polished 1.068" gem of Andean blue opal from Peru set into a sterling silver prong. It comes with an 18" silver chain in a padded black jewelry box.
