Art Deco Ruby and Diamond Bracelet Pyramidal Cabochon Rubies, Square and Baguette-cut Diamonds, Platinum and White Gold

The pyramidal cabochon is among the more architecturally distinctive gemstone cuts to emerge from the Art Deco period, its raised, faceted-dome profile catching light in a way flatter cabochon styles simply cannot replicate. This bracelet uses that cut to striking effect, setting pyramidal cabochon rubies alongside square and baguette-cut diamonds within a mounting that combines both platinum and white gold — a pairing chosen specifically to keep every metal element in the same cool tonal register as the diamonds themselves throughout the piece. That architectural ambition is precisely what distinguishes a considered commission from routine period output.

Shaping ruby into a true pyramidal cabochon, rather than a simple rounded dome, required the lapidary to control multiple angled facets on the stone's raised surface while preserving the smooth, unfaceted quality that defines a cabochon cut — a technically demanding combination of two entirely different cutting philosophies within one single stone. Carat weights and clarity grading for the rubies and diamonds are available on request from our specialists, and our team can discuss any treatment history openly during a private consultation with a serious buyer.

The geometric peak of each pyramidal ruby catches light with a directional intensity that a flat cabochon simply cannot replicate, giving this bracelet a more architectural, almost faceted presence despite the rubies technically being cabochon-cut rather than fully faceted stones in the traditional sense. Combined with the crisp square and baguette diamond accents, the overall effect sits at an interesting intersection between Deco's geometric discipline and the softer, more sculptural cabochon tradition of the period. That architectural quality gives the bracelet a presence closer to sculpture than to conventional cabochon-set jewellery of the period.

The platinum-and-white-gold construction, alongside the technically demanding pyramidal cut, marks this as a considered original commission from a workshop willing to push beyond standard cabochon shaping into more ambitious territory. Pieces demonstrating this specific cutting technique are genuinely uncommon among surviving Deco ruby jewellery, and this bracelet has been reviewed and entered into the Legacy register in recognition of that distinction and rarity. We remain glad to put that technical assessment in writing for any interested collector who requests it.

Collectors with an eye for technical rarity in gemstone cutting are invited to arrange a private viewing. Our specialists are pleased to discuss the pyramidal cabochon technique, full grading, and appropriate care for this two-metal setting going forward. Legacy's specialists remain available afterward to discuss insurance valuation and any further technical questions raised.
