One of a kind 15.47ct untreated Opal cabochon

This is the type of opal that you don't see everyday. The unique growth patterns and internal characteristics are attention grabbing, and measuring a whopping 18.3mm x 13.5mm x 11mm, there's a lot of attention up for grabs! The well defined opal crystal formations glow in whites and yellows, accented by dramatic natural inclusions wrapped in a glistening liquid luster. This large gem was sourced from Mexico, and is untreated.
