1920s Diamond Necklace
When searching for a 1920s diamond necklace, collectors encounter sophisticated pendant necklaces, fringe necklaces, and multi-strand pearl strands fastened with gem-set clasps. These jewels represent the height of the Art Deco movement, capturing a distinct architectural aesthetic.
The version most commonly met on this page is the pearl necklace featuring an intricate diamond and sapphire clasp, alongside platinum pendants set with old cut diamonds. Pieces span the 1920 period with occasional Victorian, 1930, and 1940 overlaps.
Forms range from delicate lorgnettes and simple platinum pendants to elaborate fringe designs and triple strand pearl configurations. Each object reflects the transition from heavy Victorian mountings to streamlined, machine-age elegance.
Materials and construction
Platinum serves as the primary metal for mounting stones securely while maintaining whisper-thin metal lines, often paired with 18ct white gold, 14ct gold, and silk threads for stringing pearls. Jewellers utilised this robust metal to create openwork filigree and geometric millegrain edges.
Diamonds are frequently old cut or rose cut, catching candlelight with softer facets than modern brilliants. These stones are combined with natural and cultured pearls, sapphires, aquamarines, and emeralds to create high-contrast colour palettes.

Judging quality in period jewellery
Quality rests upon the precision of the metalwork and the integration of the stones within the geometric Art Deco framework. Superior examples demonstrate meticulous hand-piercing and balanced stone proportions that elevate the entire composition.
The distinction between tiers involves the symmetry of the platinum mountings and the match of the pearls, whether single, double, or triple strand. Gemstone certification and the original condition of the silk stringing or clasp mechanisms further separate standard items from finer works.
The 1920s Diamond Necklace Glossary
- Art Deco
- A design style dominant in the 1920s and 1930s characterised by symmetry, geometric forms, and stylised motifs. This aesthetic moved away from flowing organic curves toward clean, architectural lines.
- Old cut diamond
- A hand-faceted diamond cut before modern automated standards, featuring a smaller table, higher crown, and open culet. These stones possess a distinctive warm glow under artificial light.
- Millegrain
- A decorative technique involving tiny raised metal beads along the edges of platinum or gold settings. This texture softens the metal edge and frames the diamonds.
- Lorgnette
- Folding opera glasses held by a long handle, frequently mounted in platinum and set with diamonds during the 1920s. They combined practical optics with high fashion jewellery.
- Fringe necklace
- A necklace style featuring dangling elements suspended from a rigid or flexible collar. In 1920s pieces, this typically manifests as platinum drops set with graduated diamonds.
1920s Diamond Necklace: Frequently Asked Questions
How do I care for a pearl and diamond necklace?
Store pearl strands flat in a soft pouch away from other jewellery to prevent scratching the delicate nacre surfaces. Wipe pearls gently with a damp cloth after wearing to remove oils.
Keep chemical perfumes and hairsprays away from both the pearls and the metal mountings. Have silk-strung necklaces checked periodically by a specialist to ensure the threads remain secure.
Are these diamonds certified?
Many pieces include specific gemological certification documenting stone characteristics and pearl origins. AnchorCert and other laboratory reports frequently accompany the pearl necklaces listed here.
Review individual listing details to confirm whether a certificate is supplied with the specific pendant or clasp.
What is the difference between single and multi-strand pearl necklaces?
Single strand necklaces feature one continuous line of pearls leading to the diamond clasp. They offer a classic, understated silhouette typical of everyday Jazz Age fashion.
Multi-strand versions use two or three rows of pearls, creating a fuller, more substantial neckline designed for formal evening attire.
Can I wear a 1920s pendant every day?
Platinum and gold mountings from this era are durable, but antique pieces require thoughtful handling during daily routines. Remove necklaces before swimming, exercising, or sleeping.
Treating the delicate platinum openwork and old cut stones with care preserves the integrity of the original settings.
