Vintage Long Pearl Necklace with 18ct White Gold Old Cut Diamond Clasp C.1950

1940 - 1960
Description

Vintage Long Pearl Necklace with Diamond Clasp in 18ct White Gold 

A timeless and wonderfully versatile vintage pearl necklace dating to the 1950s, featuring a single strand of beautifully matched cultured pearls that may be worn as a graceful long strand or doubled to create a classic two-row necklace.

Each pearl has been individually hand knotted and recently restrung in June 2026, ensuring both security and longevity. The pearls display a beautiful ivory-silver body colour with a rich, even lustre and are exceptionally well matched throughout the strand.

This necklace boasts an exquisite 18ct white gold diamond clasp. Designed in an elegant stylised kite-shaped frame, it is centred by a cluster of seven old cut diamonds and further embellished with old cut and eight-cut diamonds throughout. Delicate millegrain edging enhances the sparkle and craftsmanship, creating a clasp attractive enough to be worn at the front, side or back of the necklace.

Whether worn as a long single strand for understated sophistication or doubled for a more formal look, this necklace remains effortlessly elegant and endlessly wearable.

Supplied in a presentation box.

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.

Mid-20th-century pearl necklaces typically feature uniform or graduated cultured pearls secured with decorative precious metal clasps, often set with diamonds or gemstones reflecting late Art Deco and Retro styling influences.

These pieces commonly utilise saltwater or freshwater cultured pearls strung on silk thread, paired with gold or platinum clasps featuring brilliant or old cut diamonds.

Authentic mid-century pieces generally display hand-knotted silk thread between individual pearls, hallmarks on the clasp indicating precious metal purity, and characteristic gemstone cuts like old European or single cuts.

A long strand can be worn draped long for an elongated silhouette, doubled around the neck, or styled with modern tailoring to add classic elegance.

Store pearls flat in a soft-lined pouch away from direct sunlight, avoid contact with perfumes or cosmetics, and have the silk thread professionally re-strung periodically to maintain structural integrity.
