Exceptional 9ct gold, Emerald and Opal cluster ring

Stunning Cluster 9ct Gold Ring with 14 natural, facetted Emeralds to the outer ring of the cluster, surrounding spectacular inner cluster of Pinfire Opals with some of the brightest colours we have seen. The emeralds are encasing the central bright Pinfire Opal. This is a high quality ring set with quality Gems. The 9ct Gold is verified in the Hallmark with “375”, and possibly a Scandinavian Hallmark starting with what appears to be like a pigeon fantail?, and finishing with a “2” (an unusual mark). Dimensions approx.: Ring Size “M ½”  or  “6 ½” . Europe. Circa 1960’s
