Edwardian jewellery, produced during the reign of King Edward VII from 1901 to 1910, is characterised by light, airy motifs, platinum settings, and the extensive use of diamonds and pearls to create lace-like, delicate patterns.

Pendants from this era frequently utilised a combination of yellow gold and platinum, often pairing central gemstones such as opals, rubies, or sapphires with small accent diamonds.

Authentic pieces typically feature hand-cut gemstones, period-specific metal working techniques such as millegrain edges, and hallmarks corresponding to early 20th-century assay offices.

An antique pendant can be worn layered with contemporary minimalist chains to highlight its historic character, or paired simply as a focal statement piece against plain necklines.

Antique pieces should be stored individually in soft pouches, kept away from harsh chemicals and ultrasonic cleaners, and inspected regularly by a professional jeweller to ensure settings remain secure.
