1900s Edwardian Diamond & Demantoid Garnet Platinum 18k Gold Cluster Ring

A stunning c. 1900 Edwardian era diamond & demantoid garnet cluster ring, arranged in a flower-like formation with a 3 mm round transitional cut diamond in the center surrounded by five 3 mm demantoid garnets, and finally surrounded by an 18 old cut diamond halo. The elegant reticulated shoulders with the decorative grooves is a design element commonly seen on fine Edwardian rings.

The 18k yellow gold shank and shoulders support a setting topped with platinum. Impervious to tarnishing and scarcer than gold, platinum was regarded by Belle Epoque and Edwardian jewelers as a novel and superior alternative to silver (tend to discolor) and white gold (has a faint yellowish tint) for setting colorless diamonds.
