How do I secure a box clasp?

A box clasp is fastened by gently pushing the curved metal tongue into the receiving housing until it clicks firmly into place. Many designs also feature a side safety figure-of-eight catch for extra security. To release the mechanism, lift the safety catch if present and press the tongue slightly to disengage it from the housing without pulling on the pearls.

How should I store my pearl necklace?

Pearls should be stored flat in a soft pouch or lined jewellery box to prevent the silk thread from stretching and to protect the lustre from scratching against harder gems. Keeping them away from direct cosmetics and perfumes preserves the surface. Because 9ct gold is durable, the main vulnerability lies in the stringing material, which benefits from relaxed storage rather than hanging vertically under weight.

How do I date a pearl clasp?

Dating relies on a combination of the gold hallmarks stamped onto the clasp, the overall style of the mounting, and the stringing technique. Mid-century pieces often display clean geometric or floral cluster forms, while Edwardian and Victorian versions utilise padlock designs or seed pearl work. Assay office stamps and date letters on the gold provide the most precise chronological marker for the fastener.

Why are some pearls hand-knotted?

Hand-knotting involves tying an individual knot in the silk thread between each pearl, preventing the beads from rubbing against one another and causing wear. This technique also ensures that if the strand breaks, only a single pearl is lost rather than the entire set. It is a standard indicator of careful construction found across finer vintage pearl necklaces and bracelets.
