Fine jewelry of the Edwardian era used a lot of Diamonds, white Gold, and Platinum. Although Platinum had been available earlier, it had been very difficult to work with so the new technology made it more practical for jewelry. Designs were made with delicacy to blend with the current tastes for fabrics of lace and silk. The lightness of design was also made possible through the use of Millegrain and Invisible settings, as well as by new gem stone cutting techniques. Millegrain settings use metal to secure a stone with ridges of tiny beads or grains surrounding it. Platinum and gold were made into openwork designs with Knife edges, a technique that used the edge of the metal. Pieces made using these techniques were lightweight with unobtrusive settings for the stones.
