FAQs

Antique pearl necklaces from the late 19th and early 20th centuries often feature hand-knotted silk threads and intricate clasps set with precious stones like diamonds and sapphires, reflecting the artisanal techniques of the Victorian, Edwardian, and Art Deco eras.

Traditional pieces comprise genuine saltwater or freshwater pearls, threaded individually onto silk or nylon cord with knots between each pearl to prevent loss, paired with precious metal clasps fashioned from platinum or gold set with rose-cut or old-mine-cut diamonds.

Authentic period pieces typically display slight irregularities in shape and lustre under magnification, hand-knotted threading, and hallmark stamps on the metal clasp denoting the specific gold or platinum purity.

This piece can be styled as a classic focal point against minimalist modern garments, allowing the historical craftsmanship of the central clasp and the lustre of the pearls to stand out.

Pearls should be stored flat in a soft pouch away from hard metals, kept clear of cosmetics, perfumes, and hairsprays, and periodically re-strung by a professional jeweller to maintain structural integrity.
