Art Deco Emerald, Diamond, Onyx and Enamel Bandeau Bracelet Cushion-shaped Emerald, Cushion-shaped, Old and Rose-cut Dia

The bandeau silhouette brought a distinctive broad, banded proportion to Art Deco bracelet design, and this example uses that width to full advantage throughout its construction. A cushion-shaped emerald sits at the composition's heart, framed by cushion-shaped, old and rose-cut diamonds, while buff-top onyx and black enamel work fill out the surrounding architecture in deep, matte contrast. The combination of hard-stone onyx alongside applied black enamel — two entirely different materials achieving a similar visual darkness — is a detail that speaks to genuine technical range in the original workshop that made it.

Enamel work of this period was executed by hand, fired in careful stages to achieve the deep, even black seen here without cracking or discolouring the surrounding metal — a meticulous, failure-prone process that fewer workshops attempted as the technique gradually fell out of favour later in the twentieth century entirely. Paired with buff-top onyx, whose smooth domed surface offers a different textural darkness, the bracelet achieves a depth of contrast against its cushion emerald and diamond elements that few surviving pieces can match today. Carat weight and clarity for the centre emerald and the surrounding diamonds are available on request from our specialists.

The bandeau's broader proportions mean this bracelet wears with more visual weight than a slender line style, sitting close to the wrist with a substantial, architectural presence that commands attention. It is a particularly striking choice for collectors seeking a bracelet that reads clearly as a design object in its own right, distinct from simpler diamond lines seen elsewhere in the market. That architectural weight is precisely why bandeau bracelets remain a favourite among collectors seeking genuine design presence.

The combined use of onyx and hand-fired enamel within a single bandeau setting represents a genuinely uncommon technical pairing, and surviving examples in stable, uncracked enamel condition are increasingly hard to find given how fragile fired enamel becomes over a century of continuous handling. This bracelet has been carefully assessed for condition and now carries the Legacy mark following that thorough review process undertaken. We are always glad to discuss that broader material history in a relaxed, unhurried setting.

Collectors with a particular interest in period enamel work are encouraged to request a private viewing, where our specialists can discuss the enamel's condition in detail, the emerald's grading, and appropriate long-term care for this technically distinctive and rare piece, and we consider that willingness a genuine mark of quality.
