Known as prong setting in the USA, claw setting is when a gemstone is held in place by tiny slivers of metal known as ‘claws’ or ‘prongs’. The claws bend around a stone to hold it in place. Popularised in the late 1800s, claw setting leaves a stone open to light so is fitting for a faceted diamond or other stones where brilliance is coveted. The claws usually hold a stone just above the girdle. Any number of claws can be used, balancing security of the stone with the design. It is worth noting that claw settings are not as secure as bezel settings, where the stone is encased on all sides.
