After Queen Victoria's passing, her son Edward VII took the throne during the Edwardian era (1900-1915.) Here the use of platinum was developed and it flourished beautifully. Intricate lace-like patterns and filigree filled decadent cocktail rings and pendant necklaces. The platinum pieces were often backed with gold and detailed with scrolling milgrain touches. Diamonds were the stone of choice in Edwardian jewelry to create an overall white, airy, feminine look.
