Art Deco Diamond, Enamel and Onyx Cuff Bracelet Cushion and Old-cut Diamonds, Onyx and Black Enamel Plaques, Platinum

The introduction of onyx and black enamel plaques into a diamond bracelet marks this piece as belonging to the bolder, more dramatic end of Art Deco design — a movement that, alongside its geometric restraint, also produced pieces built for striking visual contrast and presence. This platinum cuff pairs cushion and old-cut diamonds against deep black plaques, the sharp tonal opposition between brilliant white stones and matte black surface creating a graphic quality rarely seen in more conventional period bracelets of the same era.

The cushion-cut diamonds bring soft, rounded brilliance to the composition, while the old cuts add their characteristic warm sparkle, both set in careful counterpoint to the disciplined geometry of the black plaques running through the design. Carat weight and individual clarity or colour grading remain available on request, and our specialists can share the complete technical file with any serious enquirer prior to purchase. The cuff's rigid platinum structure required exacting fabrication to seat both the diamonds and the enamel and onyx work securely, a level of mixed-material engineering that marks this as work from a highly capable original workshop of real standing.

This is a bracelet for the wearer who wants Art Deco's boldest visual language rather than its quieter register — a genuine statement cuff suited to eveningwear where its graphic contrast can be fully appreciated across a room. Its rigid form and mixed materials have held their integrity impressively well across decades, with no visible loss to the enamel or looseness in the stone settings under inspection. Clients drawn to bolder Art Deco expressions often pair this cuff with simpler diamond pieces elsewhere in an outfit, allowing its graphic contrast to remain the clear visual focus of the overall look. Cuffs combining diamonds with onyx and enamel in this manner are a distinctly scarce category within Art Deco jewellery, appealing strongly to collectors seeking the movement's more avant-garde expressions.

Independent gemological certification is available on request for buyers wishing to review documentation before finalising a purchase, and our advisors are glad to discuss the mixed-material construction in detail. This cuff is entered into the Legacy register as a fully authenticated piece of bold period design. We are also glad to advise on the particular care that enamel and onyx work of this age requires, since these materials demand a gentler approach than diamond-only pieces when it comes to cleaning and storage. We invite serious collectors to arrange a private viewing, with terms available to discuss directly through the Negotiation Room.
