How do I care for a platinum band ring?

Clean the metal and stones with warm soapy water and a soft brush to remove everyday oils. Avoid harsh chemicals that might affect secondary gold components or softer gemstones. Platinum is durable, but professional checks every few years ensure stone settings remain secure. The metal develops a natural surface finish over time which many collectors appreciate.

Can antique platinum rings be resized?

Most platinum bands can be adjusted by a skilled jeweller, though intricate side engraving or full eternity stone layouts require specialist care. Jewelers add or remove small sections of metal from the unadorned portion of the shank. Consult a specialist familiar with vintage construction methods to preserve structural integrity. Geometric patterns and channel-set diamonds near the shoulders restrict the available sizing range.

What is the difference between old cut and modern diamonds?

Old cut diamonds feature hand-faceted proportions designed by candlelight, resulting in broader flash patterns rather than modern brilliance. They often display higher crowns and smaller tables than contemporary stones. These historic stones match the aesthetic of Edwardian and Art Deco settings. Each cut diamond possesses individual characteristics shaped by the lapidary.

How do I identify an Art Deco platinum ring?

Art Deco rings display geometric symmetry, strong lines, and stylized motifs executed in platinum or platinum-topped gold. Settings often incorporate calibre-cut sapphires or emeralds alongside diamonds. Look for openwork galleries and millegrain borders characteristic of the interwar period. Hallmarks and construction techniques help confirm the era of manufacture.
