Vintage 1.70 Carat Unheated Ruby & Diamond Cluster Ring, circa 1970A truly gorgeous vintage ruby and diamond cluster ring. At its centre sits a vibrant, richly coloured ruby certified as natural and unheated with exceptional internal clarity (noteworthy, as rubies are typically heavily included). The ruby is framed by twelve bright, white brilliant cut diamonds, each individually set in a smooth rubover setting. Elegant, spear shaped diamond set shoulders lead to a slim, fluted shank.
