Diamond Clasp Necklace
A diamond clasp necklace pairs the quiet lustre of pearls or gemstone beads with a secure, decorative fastening set with precious stones.
Diamond Clasp Necklace
A diamond clasp necklace consists primarily of single, double, triple, or multi-strand pearl necklaces where the technical fastening serves as a focal point.
The selection spans Edwardian, Art Deco, and mid-century periods, alongside nineteenth-century and 1940s examples.
While pearls dominate the strand materials, variations include jade, opal, turquoise, and rock crystal beads paired with diamonds, sapphires, rubies, or emeralds.
Materials and Technique
Strands are constructed using natural saltwater pearls, cultured pearls, or gemstone beads, frequently secured in multi-row configurations.
Mountings utilise platinum, yellow gold, and white gold in nine-carat, fifteen-carat, and eighteen-carat purities, framing old-cut, rose-cut, and modern brilliant-cut diamonds.
