Vintage 9ct gold ring with a central Solid Opal surrounded by Garnets

A lovely Vintage 9ct Gold Ring with central solid Opal surrounded by 10 good size Garnets.

Excellent ring and the Garnets are finely faceted to give as much sparkle as possible, excellent condition, no damage or losses and Hallmarks to both inner ring sides, I being “EKRJ” the jeweller’s or Designer’s initials, and the other side appears to be a European Mark, possibly English, but difficult to distinguish. Dimensions approx.: Ring size “O”  of  “”7”, Cluster size is 9mm x 10mm; Band width 2mm at rear to 1mm at shoulder point; band thickness 1mm at rear to 3mm at tapered shoulders.
