How do I date my pendant necklace?

Examine the materials, mount styles, and any maker marks or hallmarks stamped on the reverse of the setting. Platinum and white gold mountings with calibrated sapphires or old-cut diamonds point directly to the interwar decades. Simpler silver pieces utilising butterfly wings or moulded glass often bear registry numbers or maker stamps that narrow the production year. Comparing the chain style and clasp mechanism also helps confirm the period of manufacture.

Were these worn daily or for evening?

Original owners wore these pieces for both daytime outings and evening events, depending entirely on the materials used in the drop. Silver and butterfly wing or glass pendants suited daytime dresses, while platinum and diamond drops accompanied formal evening attire. Many designs bridged the gap by using versatile geometric motifs that caught the light under indoor lighting as well as daylight.

How should I care for delicate glass elements?

Keep moulded glass and pate de verre drops away from ultrasonic cleaners, harsh chemicals, and sudden temperature changes. Wipe them gently with a dry or slightly damp soft cloth after wearing to remove skin oils. Store each necklace flat or hung separately in a lined box to prevent the glass or soft stones from striking other jewellery.

What is the difference between paste and crystal?

Paste is a heavy, high-refractive lead glass that artisans cut by hand to imitate precious gems like aquamarine, sapphire, and diamond. It was shaped specifically for interwar costume jewellery. Crystal refers to natural colourless quartz or high-purity glass without the coloured metallic oxides added to paste formulations. Both materials feature prominently in period necklaces for their clarity and brilliance.
