Coloured Diamond, Diamond and Emerald 'lionne' Bangle Brooch Round Coloured Diamonds and Diamonds, Marquise-shaped Emera

This coloured diamond and emerald bangle brooch combines round coloured diamonds and white diamonds with marquise-shaped emeralds, set in eighteen karat yellow gold bearing French marks alongside silver, in a design engineered with genuine dual functionality: the central body detaches fully from the bangle and may be worn separately as a brooch. This kind of convertible construction was a hallmark of sophisticated jewellery design in earlier eras, requiring the goldsmith to solve for structural integrity in two entirely different wearing configurations rather than one.

The combination of round coloured diamonds, white diamonds, and marquise emeralds gives the piece a genuinely rich palette, the elongated emerald shapes providing a cool green counterpoint to the warmth of the coloured diamonds and the brilliance of the white stones. Building a mechanism robust enough to function reliably as both a bangle and a standalone brooch, without compromising the security of any single stone across either configuration, demanded a level of goldsmithing precision considerably beyond a fixed-form piece, and the French marks present here attest to the rigorous hallmarking standards applied to gold work of this quality.

Worn as a bangle for formal daytime occasions or detached and worn as a brooch on eveningwear, this piece offers a versatility genuinely uncommon among fine jewellery, effectively functioning as two considered acquisitions within one. As an heirloom, convertible pieces like this tend to be particularly treasured precisely because of their flexibility, giving each successive wearer the freedom to style the piece according to their own taste and occasion. Collectors of fine antique and vintage jewellery often seek out convertible mechanisms specifically for this dual functionality.

Independent certification for the diamonds and emeralds within is available on request, and our advisors are glad to demonstrate the detachable mechanism and discuss construction detail with any serious enquirer. Our advisors can also walk through how a convertible piece like this is typically insured, since coverage sometimes needs to account for both wearing configurations independently rather than treating the piece as a single fixed form. Care recommendations specific to convertible mechanisms are available on request, since the detachable fitting benefits from periodic professional inspection to keep both wearing configurations functioning smoothly for years to come.

This piece is entered into the Legacy register as a distinguished convertible bangle-brooch holding. We welcome a private viewing to see both wearing configurations demonstrated in person, and we are glad to discuss acquisition terms and provenance without pressure.
