The John Hardy Heishi Chain Bracelet, Sterling Silver, Black Onyx, 6MM brings the distinctive texture of the Heishi Collection together with the structured character of a sterling silver box chain. Artisan handcrafted in more than 99% reclaimed sterling silver, the bracelet features substantial 6MM hand-cut black onyx beads arranged along a silver chain, creating a considered balance between natural stone and polished metal.

The design centres on treated black onyx, selected for its deep, saturated colour. John Hardy identifies the stone as ethically sourced and treated, while noting that natural variation remains an important characteristic of its Heishi designs. Variations in the stone's colour, markings and individual character mean that every bracelet has its own appearance.

At 6MM, the Heishi beads provide a substantial profile while retaining the relaxed, tactile character associated with the collection. The hand-cut construction gives each bead its own subtle shape and surface character rather than creating a completely uniform appearance. John Hardy describes its Heishi Collection as featuring hand-cut beads strung together for a “perfectly imperfect” texture, using a variety of natural hardstones and shells.

The black onyx beads are paired with a sterling silver box chain, introducing a clean linear element between the organic forms of the stones. This contrast between rounded hardstone beads and structured chainwork gives the bracelet a distinctive visual rhythm.

A seamless hook clasp completes the design. The streamlined closure maintains the bracelet's clean appearance while providing the fastening specified by John Hardy.

John Hardy states that the bracelet is crafted in more than 99% reclaimed sterling silver and uses ethically sourced treated black onyx. The brand is a Responsible Jewellery Council member and states that its precious metals and gemstones are sourced in accordance with ethical social and environmental practices throughout its jewellery supply chain.

The Heishi Collection draws on an elevated beach aesthetic, translating the casual visual language of hand-strung natural beads into fine jewellery. Some stones within the collection are treated to enhance vibrancy and clarity, while others are left closer to their natural state. This particular bracelet uses treated black onyx, giving the design its distinctive dark colour.

The John Hardy Heishi Chain Bracelet, Sterling Silver, Black Onyx, 6MM offers a sophisticated interpretation of natural-stone jewellery, combining substantial hand-cut onyx beads, reclaimed sterling silver and a structured box chain. Its contrasting materials and artisan construction give it a distinctive place within the John Hardy Heishi Collection.

Design & Symbolism

The Heishi Collection is defined by hand-cut beads, natural hardstones and tactile variation. John Hardy describes the collection as bringing beach-inspired aesthetics into fine jewellery, with beads intentionally retaining individual variations in shape, texture and character.

For this edition, the deep black tone of treated onyx provides the central visual identity. The dark stones are contrasted with the cool surface of sterling silver, while the box chain introduces a more structured element to the organic beadwork.

The hand-cut nature of the Heishi beads means that individual stones may differ subtly from one another. John Hardy specifically emphasizes these variations as part of the character of the collection, so each bracelet has its own combination of natural markings and surface details.

The seamless hook clasp complements the understated construction, keeping attention on the contrast between the black onyx beads and silver chain.
