Art Deco Diamond Clasp
An art deco diamond clasp secures multi-strand pearl necklaces, bringing geometric brilliance to traditional pearl strands.
Art Deco Diamond Clasp
An art deco diamond clasp typically fastens a single, double, or triple strand of pearls, serving both a functional and decorative purpose at the back or side of the neck. These pieces primarily date from the 1920s and 1930s, reflecting the clean lines and geometric motifs characteristic of the period.
The most common version met on this page is a pearl necklace featuring a platinum or white gold clasp set with diamonds and occasionally accented by sapphires or emeralds. Alongside true Art Deco items, the selection includes Edwardian and mid-century examples where diamond-set clasps secure beaded or saltwater pearl strands.
Necklaces dominate the forms seen, ranging from simple single strands to elaborate multi-strand arrangements with French or floral designs. The combination of lustrous pearls and sparkling diamonds set in white metals defines the visual identity of these items.
Materials and construction
Clasps are constructed using platinum or white gold, such as 18ct white gold, providing a bright, durable setting that enhances the brilliance of the diamonds. Gemstones including rose-cut and old-cut diamonds are meticulously mounted alongside natural saltwater, cultured, or freshwater pearls.
Many pieces incorporate additional coloured gemstones like sapphires or emeralds within the clasp design to create contrast and floral or geometric patterns. Silk threading is utilised for stringing the pearl strands, often restrung to ensure the longevity and security of the necklace.
Several pieces arrive with certified pearls and French marks, proving that antique clasps love a well-travelled passport.
Distinctions in quality
The sophistication of the metalwork and the precision of the stone setting separate standard examples from superior pieces. Higher quality clasps feature intricate platinum work with well-matched old-cut or rose-cut diamonds, sometimes accompanied by gem lab certificates.
The origin and grading of the pearls also determine the standing of the piece, with natural saltwater pearls commanding greater interest than cultured or freshwater alternatives. Uniformity in pearl grading and the integrity of the silk stringing further distinguish the finer necklaces in the range.
The Art Deco Diamond Clasp Glossary
- Art Deco
- A design style spanning the 1920s and 1930s characterised by geometric symmetry and stylised motifs. This aesthetic heavily influences the architecture of the clasps.
- Platinum
- A dense, durable white metal prized in jewellery manufacture for its strength in secure stone settings. It provides the backbone for many fine diamond clasps.
- Rose-cut
- An antique diamond cut featuring a flat base and a domed crown with triangular facets. This cut imparts a soft, twinkling lustre rather than modern brilliance.
- Old-cut
- A precursor to the modern brilliant cut, featuring a smaller table and high crown typical of antique diamonds. These stones were shaped by hand to catch candlelight.
- Saltwater pearl
- A pearl formed in marine molluscs, historically gathered naturally before cultured varieties became prevalent. They display a distinct orient and depth of lustre.
Art Deco Diamond Clasp: Frequently Asked Questions
How do I secure an art deco diamond clasp?
Most clasps utilise a tongue and box mechanism where a spring-loaded tongue clicks securely into a housing. Additional safety chains are frequently attached to provide extra security during wear.
Checking the tension of the tongue ensures the clasp holds firmly when fastened. A secure click indicates the locking mechanism functions correctly.
Can these necklaces be worn daily?
Pearl necklaces with secure metal clasps can be worn regularly provided proper care is taken. Pearls are relatively soft and sensitive to chemicals, perfumes, and cosmetics.
Removing the necklace before swimming or exercising prevents damage to the silk thread. Storing the piece flat in a lined box protects both the pearls and the diamond setting.
How do I tell an Edwardian clasp from an Art Deco one?
Edwardian clasps tend to feature delicate, lace-like platinum work with floral or garland motifs. They emphasise lightness and intricate filigree design.
Art Deco clasps shift towards bold geometric shapes, symmetry, and architectural lines. They often incorporate calibrated coloured gemstones alongside diamonds.
What is the difference between natural and cultured pearls here?
Natural pearls formed without human intervention in marine environments, making them scarce and historically significant. Cultured pearls involve human assistance in initiating the growth process within oysters.
Gem certificates often specify the origin of the pearls. Both types appear alongside diamond clasps across different periods.
