A rhodium plated 925 sterling silver square signet ring set with a 10mm black onyx. Band tapers from 13.7mm to 5.5mm. Available in whole sizes 9–12.

This square signet ring is set with a 10mm black onyx stone in a rhodium plated .925 sterling silver setting, with a band that tapers from 13.7mm at the top to 5.5mm at the base. A signet ring is characterised by a flat, resolved face at the top of the band — historically a surface used to carry an engraved seal or emblem for impressing into wax, and in contemporary jewelry a design form in which the top face of the ring is the primary visual element. The signet face of this ring is square in form, presenting the 10mm black onyx as a square or square-adjacent element set within the rhodium plated square frame of the signet face. At 13.7mm of band width at the top and 5.5mm at the base, the taper ratio is approximately 2.5:1 — the top of the band is two and a half times the width of the base. This is a pronounced taper that concentrates visual mass at the top of the ring where the onyx signet face sits, while the shank becomes substantially narrower as it descends, reducing the ring’s footprint on the finger sides and creating a strong transition between the wide signet top and the narrow base. The 10mm black onyx is the central visual element of the ring. Onyx is a variety of chalcedony — a cryptocrystalline form of quartz. Black onyx presents a deep, opaque black body colour with a smooth, even surface that returns a low to moderate lustre. The even, opaque black surface of the onyx contrasts strongly with the white rhodium plating of the signet frame and band: the deep black stone and the bright white rhodium surface occupy opposite ends of the value scale, producing a high-contrast, graphic black-and-white combination at the ring face. The band is rhodium plated over .925 sterling silver. Rhodium plating provides a bright white finish that is harder and more tarnish-resistant than unplated sterling silver. The ring is available in whole sizes 9 through 12.

A refined statement ring for anyone looking for a black onyx signet ring in rhodium plated sterling silver — a 10mm black onyx set in a rhodium plated .925 sterling silver square signet, band tapering 13.7mm to 5.5mm, whole sizes 9–12.

✨ How to Wear

Wear on any finger. The square signet face sits at the top of the tapered band. Available in whole sizes 9–12 only; half sizes are not available. The rhodium plated black onyx square signet ring pairs naturally with silver and white gold jewelry. The black onyx surface and rhodium frame are most graphically defined in directional light, where the high-contrast black-and-white combination of the onyx and rhodium reads most clearly.
