How do I care for art deco blue jewellery?

Store each piece separately in a lined box to prevent softer materials like enamel or butterfly wings from scratching against harder diamonds and sapphires. Clean silver and gold settings gently with a soft brush and warm soapy water, avoiding harsh ultrasonic cleaners that might damage treated gems or enamel.

What periods do these pieces come from?

The majority of pieces date from the 1920s and 1930s during the height of the Art Deco movement, characterised by clean geometric lines and platinum settings. Later items extend through the 1940s, 1950s, and 1960s, reflecting the enduring influence of these designs and later revival periods.

How can I tell sapphires from paste?

Genuine sapphires display natural inclusions under magnification and feel noticeably cooler to the touch than glass substitutes. Paste stones often show tiny air bubbles within the material and feature softer facet edges due to being moulded rather than cut.

What metals were commonly used?

Platinum and 18ct white gold were favoured during the 1920s to provide a bright, neutral backdrop that enhanced blue stones and diamonds. Yellow 18ct gold, standard silver, and silver gilt also appear frequently, particularly in bracelets, brooches, and pieces utilising enamel or butterfly wings.
