A vertex is the point where two lines meet to form an angle — the exact opposite of a curve. The Vertex Ring builds on that: a rectangular-cut cubic zirconia set into a band with no softening anywhere, so the whole piece reads as drawn rather than moulded.
Made from premium stainless steel in warm 18k gold plating or a cool platinum tone, it is waterproof, tarnish-free and hypoallergenic. Rings take more friction than any other piece of jewellery, which is where steel earns its place — a plated brass ring in this shape would show wear at the corners within a season.
Why You'll Love It
- Premium stainless steel that resists the scratching and knocks rings take daily.
- Waterproof and tarnish-free — no need to remove it to wash your hands.
- Hypoallergenic, so comfortable for continuous wear.
- A rectangular-cut cubic zirconia with clean, architectural facets.
- A sharp geometric silhouette that stands apart from rounder ring shapes.
- Available in sizes 16, 17 and 18, in 18k gold plating and platinum tone.
- A modern statement that still works in a professional setting.
How to Style It
Vertex is the ring that gives a stack its structure. Set it against the organic, textured Dune Twist Ring and let the two approaches argue, or line it up with the slim Pávé Line Ring for a stack that moves from a single stone to continuous sparkle. Worn with the Angles Earrings the same rectangular cut appears at the ear — an easy two-piece sell.
Frequently Asked Questions
Which size should I choose?
Vertex comes in 16, 17 and 18, which correspond to the inner diameter in millimetres — size 17 fits a finger with a 17 mm inner diameter. Measuring an existing ring across its inside is the most reliable method.
Will it scratch or tarnish?
Stainless steel is considerably harder than sterling silver or plated brass, so it holds up to daily wear. It does not tarnish at all.
Can it be worn in water?
Yes — including showering and swimming. We recommend removing it for heavy lifting or manual work, as any ring meets more friction than other jewellery.
