This amazing boulder opal is the best gem opal we have ever had in a ring. It has outstanding clarity with crisp sharp colours and patterns without equal.

The block harlequin pattern is overlaid with a broad flash and chaff patterns in truly remarkable crispness. An heirloom piece, adorned with brilliant white diamonds and set in 18K gold. Viewings are by appointment only and can be arranged virtually via our online concierge service.
