John Hardy Heishi Gem Swiss Blue Topaz and Diamond Charm Necklace in Sterling Silver, 16–18 in [NBS290211BUSBTDI]

The John Hardy Heishi Gem Charm Necklace NBS290211BUSBTDI brings together vivid colour, refined sparkle and expressive handcrafted detail. At its centre is a cushion-cut treated Swiss blue topaz, prized for its bright, saturated blue tone. Micro-pavé white diamonds totalling 0.04 carat frame the gemstone, adding a delicate edge of brilliance without competing with its vibrant colour.

The elongated central pendant measures approximately 25mm by 8mm and is crafted in high-polish Sterling Silver. Smaller blue enamel bead stations, measuring approximately 7mm by 5mm, extend the colour across the necklace and complement the cool tone of the Swiss blue topaz. The combination creates a lively composition that feels polished yet playful.

Part of John Hardy’s Heishi Gem Collection, the necklace reflects the collection’s emphasis on hand-cut forms, coloured gemstones and unexpected combinations. Its arrangement of silver, painted enamel and gemstone elements gives the piece texture and visual rhythm while preserving a lightweight, contemporary appearance.

The necklace is artisan handcrafted in more than 99% reclaimed Sterling Silver using ethically sourced white diamonds and treated Swiss blue topaz. Its 2.5mm gauge provides a delicate profile that allows the colourful pendant and enamel stations to remain the focus. A lobster clasp secures the necklace for comfortable everyday wear.

Designed with an adjustable length of 16 to 18 inches, the necklace can be positioned close to the base of the neck or allowed to rest slightly lower near the collarbone. This adjustable range makes it easy to coordinate with different necklines or combine with longer chains for a layered arrangement.

Wear it alone to highlight its bright blue palette, or pair it with understated Sterling Silver earrings and bracelets for a cohesive look. The Swiss blue topaz also works beautifully alongside white diamonds, cool-toned gemstones or restrained yellow-gold accents. Unlike John Hardy’s individual Heishi Gem charms, this is a complete necklace with the gemstone pendant, enamel stations and chain included.

Design & Symbolism

Swiss blue topaz is often associated with clarity, calm and open communication. Its vivid blue colour gives the necklace an uplifting presence, while the surrounding white diamonds introduce light and refinement. The enamel stations carry the blue palette across the design, creating a sense of movement and continuity inspired by the colourful character of the Heishi Gem Collection.

Styling

Wear the necklace at 16 inches for a closer placement near the base of the neck or extend it to 18 inches for a more relaxed position around the collarbone. Its vibrant blue tones pair naturally with white, navy, denim and other cool neutrals. For layered styling, combine it with a longer, understated Sterling Silver chain that allows the topaz pendant to remain the focal point.
