Our craft

Four windows, drawn small enough to wear.

Every CELVARONI piece starts as one of four Gothic window shapes, drawn with a compass and cut as openwork in 18K gold-plated 316L stainless steel, with sapphire or ruby enamel in some openings.

Holding a Rose Window Pendant up to the light

Why windows

A Gothic window is geometry you can stand in front of. A pointed arch is two arcs of the same radius that meet at the top. A trefoil is three circles set around a centre; a quatrefoil is four. A rose window divides a circle into petals that all point to the middle. Masons set these shapes out with a compass and a straight edge, and that is still how we start.

We draw our own versions of these general window types. None of our pieces copies a particular building, and we do not use religious symbols as decoration: what interests us is the shape of the opening and the way light passes through it.

Four windows, five kinds of piece

Each window is cut into earrings, pendants, rings, bracelets and hair pins, so everything in one window shares the same drawing. That is why the shop is sorted by window rather than by trend: pick the window you like, and the earrings, pendant and ring already belong together.

  • I · Lancet: the tall pointed arch. Slim drops, narrow bands and long links.
  • II · Trefoil: three lobes in a circle. Compact, soft-edged, close to the ear.
  • III · Quatrefoil: four lobes with pointed cusps, framed in a circle. Graphic and balanced.
  • IV · Rose window: a circle of petals. Our largest and most detailed drawings.

What the pieces are made of

Every piece is 316L stainless steel with 18K gold plating. Some openings are filled with enamel in two colours, a deep sapphire blue and a ruby red, set flush inside the gold outline, the way coloured glass sits in a window. Enamel is opaque: it gives colour to the metal, and the openings left empty are what let light through.

Plating is a surface layer. It wears gradually with use, and how quickly depends on skin, wear and care; our care guide explains how to keep it longer. We describe our materials plainly: we do not claim that a piece is solid gold, hypoallergenic or waterproof.

Measured, not guessed

Openwork changes how a piece sits and catches the light, so every product page lists its size in millimetres and its weight in grams, and rings come in UK sizes J to R with EU and US equivalents. Openwork can also catch on loose knits; we say so on every page.

Made to our drawings

Our pieces are produced to our drawings by a specialist jewellery manufacturer.

I Lancet A single tall opening that closes in a point. The simplest window in a stone wall, and the most upright: slim drops, narrow bands and long links. II Trefoil Three rounded lobes cut into a circle or set under an arch. Compact and soft-edged, it sits close to the ear and the collarbone. III Quatrefoil Four lobes around a centre, symmetrical from every side. Our most graphic shape, made for studs, signets and links that repeat. IV Rose Window A round window divided by radiating petals, the largest and most detailed of the four, its petals left open or filled with sapphire and ruby enamel.
