The Edwardian Era was named after King Edward VII, whose reign lasted from 1901 to 1910.  The strength of platinum was showcased as diamonds were set in airy, lace-like, openwork filigree settings.  Millegrain (or milgrain) detailing was common, giving a soft, coin edge look to platinum pieces.  Ribbons, bows, tassels and garlands were all popular motifs during the Edwardian jewelry period.
