What defines 1920s platinum diamond jewellery?

These pieces are characterised by strong geometric lines, symmetrical patterns, and the prominent use of platinum alongside old cut diamonds. Coloured gemstones like sapphires and rubies frequently provide contrast within the designs. The items span everyday rings and brooches to elaborate drop earrings and fringe necklaces, all reflecting the distinctive Art Deco aesthetic of the period.

How do I care for vintage platinum jewellery?

Platinum is a durable and robust metal that resists tarnishing, making it suitable for regular wear. Gentle cleaning with warm soapy water and a soft brush maintains the lustre of the metal and stones. Store pieces individually in soft pouches to prevent scratching between the diamonds and softer coloured gemstones or gold mountings.

Are these pieces from the 1920s?

The listings encompass items primarily dated to the 1920s and 1930s, reflecting the height of the Art Deco movement. Occasional pieces from the Edwardian era and the 1940s also appear alongside the core 1920s selection. Datings are derived from the specific design characteristics, metal combinations, and stone cuts recorded in the individual item descriptions.

What metals are used besides platinum?

While platinum is the dominant white metal used for setting diamonds during this era, 18ct yellow gold and 18ct white gold also appear frequently. Some items combine platinum heads with gold shanks or incorporate tricolour metal elements. These mixed metal configurations reflect the transitional preferences of workshops operating during the 1920s and 1930s.
