How do I care for a platinum diamond necklace?

Clean platinum and diamond pieces gently using warm soapy water and a soft brush to remove accumulated oils from the settings. Avoid harsh chemical dips, particularly if the necklace incorporates pearls, emeralds, or opals. Store the necklace flat in a lined box or separate compartment to prevent delicate platinum links from tangling or scratching adjacent pieces.

Can I change the length of the chain?

Altering the length requires caution, as many vintage platinum chains feature integrated construction or original clasps that should remain unmodified to preserve historical integrity. A specialist jeweller can often add a matching extender or source a complementary period chain if a longer drop is necessary. Original fittings and hallmark placements on the chain should be documented prior to any modification work.

What is the difference between Edwardian and Art Deco styles?

Edwardian platinum and diamond necklaces emphasise light, lace-like platinum work, floral garlands, bows, and fluid organic curves influenced by the Belle Époque. Stones are set to appear weightless and airy. Art Deco necklaces shift toward bold geometric patterns, symmetrical lines, strong contrasts with onyx or calibre-cut gems, and streamlined architectural shapes characteristic of the 1920s and 1930s.

Are coloured gemstones natural in these necklaces?

Many pieces incorporate untreated sapphires, emeralds, aquamarines, rubies, and natural saltwater pearls that reflect the mining sources and gemological standards of the early twentieth century. Certification reports often accompany significant coloured stones to verify their origin and treatment status. Coloured gems were chosen to complement the bright white sparkle of old cut diamonds within platinum mountings.
