Platinum is a rare, heavy and extremely noble metal of a silvery-white colour, one of the most expensive in jewellery. Unlike gold alloys, platinum is used almost pure (95%), so it is hypoallergenic. Its chief virtues are exceptional strength and resistance: platinum does not tarnish, oxidise or wear away, so it holds precious stones in settings ideally, keeping them secure for years. The natural whiteness of platinum needs no rhodium plating (unlike white gold) and serves as a perfect neutral background for diamonds, emphasising their brilliance. Platinum symbolises eternity and restrained, genuine luxury without showy glitter.
