18ct White Gold Clasp
These 18ct white gold clasp pieces secure fine pearl necklaces across several twentieth-century periods, offering both security and decorative detail for daily wear.
18ct White Gold Clasp
An 18ct white gold clasp primarily secures pearl necklaces, serving as both a functional fastener and an integrated design element. When you search for an 18ct white gold clasp, you encounter fastenings attached to single, double, triple, and multi-strand pearl necklaces.
The pieces on this page span the Edwardian era through the 1920s, 1930s, 1950s, and 1960s. Art Deco, Mid-Century, and Modern Fine Jewellery styles dominate the selection alongside traditional Edwardian arrangements.
Most examples combine the cool metallic tone of 18ct white gold with gemstones such as diamonds, sapphires, rubies, turquoises, and amethysts. These fastenings range from simple box hinges to intricate cluster designs set with old-cut diamonds.
Materials and construction methods
Makers construct these fastenings using 18ct white gold to provide a durable, pale metal base that holds precious stones securely. This metal complements the lustre of both natural and cultured pearls.
Goldsmiths set diamonds, sapphires, rubies, and other stones into the white gold framework using traditional claw, bezel, or pavé techniques. Many of these clasps integrate directly into multi-strand necklaces alongside silk threading and restrung layouts.
Some mid-century clasps hide the fastening mechanism entirely within a massive gemstone cluster, turning a functional hinge into the visual centrepiece.
Quality variations in the range
The standard of an 18ct white gold clasp depends on the precision of the metalwork and the quality of the accompanying gemstones. Finer examples feature well-matched diamonds and coloured stones with secure box mechanisms that click firmly into place.
The integration between the clasp and the pearl strands influences the overall execution. Superior pieces balance the weight of multi-row pearl necklaces with substantial, securely mounted precious metal and stone clusters.

18ct White Gold Clasp: Frequently Asked Questions
Can an 18ct white gold clasp be restrung with new pearls?
A jeweller can attach an existing 18ct white gold clasp to newly strung pearl strands using traditional silk or synthetic cord. Many historical necklaces require periodic restringing to prevent cord degradation.
When restringing, the specialist ties individual knots between each pearl to protect the stones from rubbing together. This process preserves the original clasp while ensuring the necklace remains structurally sound.
How do I date an 18ct white gold clasp?
Dating relies on the gemstone cuts, the mounting style, and the overall design characteristics of the accompanying necklace. Edwardian and Art Deco pieces display distinct geometric or delicate garland motifs, whereas 1950s and 1960s items often feature bolder cluster settings.
Hallmarks stamped on the metal tongue or housing also provide official assay office marks and date letters. Comparing these details against known period styles confirms the manufacturing era.
How do I clean a pearl necklace with a white gold clasp?
Clean pearls gently using a soft, damp cloth without submerging the entire strand in liquid, which weakens traditional silk threading. White gold metalwork tolerates mild soapy water on the clasp alone.
Keep chemical cleaners, perfumes, and cosmetics away from both the pearls and the clasp to prevent surface damage. Lay the necklace flat to dry completely before storing it in a lined box.
