From the Polly Wales website:
“Polly Wales’ renegade approach to jewelery has deep roots. Its origin-point can be traced back to the United Kingdom in the 90s, where she spent her youth submerged in the national counter-culture movement and rave scene.” Her designs have become incredibly popular, specifically her cast-not-set methods of casting directly with molten gold and gemstones, as opposed to the traditional methods of casting and then setting stones afterwards. This ring features her signature milgrain and bead setting along the shoulders and shank, with claw prongs holding in the most magnificent antique rose cut diamond. This 3.46ct rose cut is spready and shimmery with the most unique shape and faceting. A beautiful ring choice for somebody looking to marry antique diamonds with bold style.
