During the Edwardian era, advances in metal fabrication finally allowed for the use of platinum in jewelry (which still remains extremely popular today). This advance makes jewelry dating much easier - if a piece is made with platinum, we can be fairly sure that it was made in the early 20th century or later. Because of the strength of platinum, its use allowed jewelers to produce more intricate, detailed pieces. Some Edwardian engagement rings are so detailed it appears that the diamonds are set in lace instead of metal. Jewelry from the Edwardian period was light and delicate, and using as many diamonds as possible in a design was essential. Additionally, a new type of decorative enhancement called “milgraining” was used extensively during this period. Milgraining involves a small border of platinum beads set around the edges of a piece of jewelry that adds a soft, elegant look.
