An antique ruby and diamond double row target cluster ring, with a cushion shaped, faceted ruby, in the centre, in a four claw setting, surrounded by a two row, stepped cluster, with smaller old-cut diamonds, in the first row. The old-cut diamonds, in both rows, are in claw settings and are spaced, on the outer edges, with rose-cut diamonds, in cut down settings, with air gaps between each row, with a split shouldered shank, mounted in yellow gold, circa 1850. Electronically tests as 18ct gold.
