Vintage Sterling Silver Opal Ring

An INSANE c.1970s HEAVY Sterling silver ‘jigsaw/thunderbolt’ ring set with hypnotic abraded opals

A truly unique piece that I can assure you is legal carry despite its size and weight 

Perhaps a bespoke/commissioned piece or maybe the lack of hallmarks implies it was made by a jeweller for themselves 

The metal has been XRF tested and a purity of 92.5% silver (Sterling) confirmed 

Weight - 53.4g

Size - UK S 1/2
