Vintage Three Row Pearl Necklace with Natural Sapphire & Diamond Floral Silver Clasp with Gem Report

1940 - 1960
Description

1950s Triple Strand Freshwater Pearl Necklace with Sapphire Floral Clasp

An exquisite vintage three-row cultured pearl necklace, dating from circa the 1950s and distinguished by a magnificent natural sapphire-set floral clasp.

The necklace comprises three graduated strands of creamy freshwater cultured pearls, individually hand-knotted and arranged to sit gracefully around the neckline. Measuring approximately 6.1–6.5mm, the near-round pearls display attractive pink and green overtones and excellent to very good lustre.

Its most striking feature is the beautifully modelled flowerhead clasp. Crafted in 925 silver, the clasp is set with a dramatic arrangement of seventeen natural blue sapphires in oval, marquise and round cuts, complemented by four small sparkling diamond accents. The deep blue stones form a richly dimensional floral cluster measuring approximately 24mm × 25mm.

The clasp can be worn at the back or front to one side, transforming the necklace from a traditional three-row pearl choker into a wonderfully glamorous statement jewel.

The necklace is accompanied by a Birmingham Assay Office Pearl Jewellery Report dated 29 July 2026. The report confirms that the pearls are beaded cultured freshwater pearls and that the clasp has been XRF tested as 925 silver and is set with natural sapphires.

A beautiful and feminine mid-century necklace, combining the timeless elegance of creamy pearls with the rich colour and sparkle of a jewel-set floral clasp.

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.

A multi-strand vintage pearl necklace consists of two or more nested rows of matched pearls secured by a central decorative clasp. Popularised in the mid-20th century, these necklaces often incorporated intricate floral or geometric clasps set with gemstones.

These pieces typically feature cultured or natural pearls hand-strung on silk thread with knots between each bead. Clasps are crafted from precious metals such as sterling silver, white gold, or platinum, and are frequently set with gemstones like sapphires, rubies, or diamonds.

Authentic pieces generally exhibit individually knotted strands, fine metal hallmarks on the clasp, and natural variations in pearl luster and shape. Gemstone clasps should feature secure prong or bezel settings rather than glued elements.

A multi-strand pearl necklace can be paired with an open-neck evening dress to highlight the decorative clasp, or worn against a high-neck velvet top for modern elegance. The clasp can be worn at the back or positioned to the side as a focal accent.

Pearls should be wiped gently with a soft, damp cloth after wearing to remove oils and kept away from harsh chemicals or perfumes. Restringing on fresh silk thread is recommended periodically to preserve the integrity of the strands.
