1920s Triple Strand Pearl Necklace with Art Deco Jadeite Clasp with Birmingham Assay Office Gem Report

1900 - 1920
Description

Art Deco Triple Strand Pearl Necklace with Jadeite Clasp, 1920s, Certified

A wonderfully elegant Art Deco triple strand pearl necklace, dating to the 1920s and finished with a striking jewelled clasp set with jadeite and zircon stones.

The three strands of cultured saltwater pearls have a soft cream tone with delicate pink and green overtones. Their near-round, semi-baroque and baroque forms give the necklace great charm and individuality, with the softly irregular pearls creating the natural movement and character so often admired in fine period pearl jewellery.

The necklace sits beautifully when worn, with the graduated strands falling gracefully around the neckline. Each pearl is individually hand-knotted, a traditional sign of quality and care, and the substantial weight gives the necklace a lovely presence.

The clasp is a beautiful feature in its own right. Designed in a bold Art Deco style, it is centred with an oval cabochon jadeite, rub-over set in yellow gold. The surrounding geometric white gold setting is decorated with 16 zircons and fine millegrain detail, giving the clasp the crisp, architectural look associated with 1920s jewellery design. A safety chain is fitted for added security.

This necklace is accompanied by a Birmingham Assay Office Pearl Jewellery Report, confirming the pearls as beaded cultured saltwater pearls, with the green stone identified as jadeite and the tested colourless stone identified as zircon.

A refined and highly wearable period pearl necklace, combining classic elegance with the distinctive glamour of Art Deco design.

Every single antique dealer on our platform is individually approved by our internal team. We verify their professional trade history, ethical standards, and photographic quality to ensure a secure, high-standard buying environment. Upon joining, every dealer agrees to a strict 9-point code of conduct. While issues can occasionally arise, our dealers typically resolve them swiftly and directly with the buyer. In fact, since our founding in 2002, Sellingantiques has only had to step in to help resolve an issue on roughly five occasions—a true testament to the quality of our dealers and their dedication to your happiness.
Our dealers are highly experienced in packing and shipping fragile, high-value antiques. Because you are in direct contact with the dealer, you will be able to easily go through all available shipping and insurance options together to ensure your item arrives safely.
Antiques are the ultimate green purchase. By choosing historical pieces over newly manufactured goods, you completely eliminate the carbon footprint of modern mass production while preserving exceptional, timeless craftsmanship.

Art Deco pearl necklaces from the 1920s frequently feature multi-strand arrangements draped in concentric layers, paired with geometric clasps set with contrasting gemstones such as jadeite, onyx, emeralds, or diamonds.

These pieces were typically constructed using natural or cultured saltwater pearls hand-knotted on silk thread, fitted with platinum or white gold clasps set with precious gemstones and enamel.

Authentic period pieces display period-correct assay marks or makers marks on the clasp, irregular hand-knotted threading, geometric Art Deco gem-setting techniques, and wear consistent with age around the drill holes.

An antique multi-strand pearl necklace can be styled modernly by draping it against minimalist evening attire, or mounted inside a glazed linen shadow box as a framed decorative heirloom display.

Pearls should be stored flat in a soft cloth pouch away from direct sunlight, kept clear of hairsprays or perfumes, and periodically re-strung on fresh silk thread to prevent breakage.
