18ct Gold, 18.8ct Boulder Opal & 0.6ct VS2-SI1 Diamond Pendant. Includes WGI report.

This is a Natural Matrix Opal, a geological marvel where the precious opal has woven itself through the host stone. Unlike Boulder Opals, which sit on a solid ironstone backing, a Matrix Opal features the "play-of-colour" distributed throughout the entire structure. This creates depth; as the pendant moves, veins of green and orange ignite from deep within the stone’s heart. It feels raw and intriguing

​This pendant has been fully certified by the World Gemological Institute

​The opal: A massive 18.80-carat bezel set Opal. 

​The Diamonds: 0.60ct of Round Brilliant diamonds. Graded G-H colour and VS2-SI1 clarity, providing a crisp, white fire that frames the opal without distracting from its natural play-of-colour.
