How do I date an antique aquamarine necklace?

Dating relies on the combination of metal purity marks, stone cuts and prevailing design styles. Edwardian examples often display yellow gold with seed pearls in foliate drops. Later Art Deco and vintage pieces typically utilise platinum or white gold with geometric mountings. Hallmarks and maker's marks, where present, help confirm the exact period of manufacture.

What metals were used in vintage aquamarine necklaces?

Early twentieth-century pieces predominantly employ 9ct and 15ct yellow gold, transitioning to platinum and white gold as fabrication techniques evolved. Mid-century items frequently feature 14ct or 18ct yellow and white gold. Platinum gains prominence in Edwardian and Art Deco mountings due to its strength and bright finish.

How should I care for an antique aquamarine pendant?

Care requires gentle cleaning with warm soapy water and a soft brush, avoiding harsh chemical dips or ultrasonic cleaners. Seed pearls and foil-backed stones are particularly sensitive to moisture and require extra caution. Store the necklace flat in a lined box to prevent the chain from tangling and to protect the stones from impact.
