KERÁ – create your ring

A ring size is not "roughly right".

You can measure yourself — wrap a strip of paper around your finger, mark where it meets and measure with a ruler. There are tables online that convert millimetres to ring size.

But the best option is to pop into your nearest jeweller. They’ll measure accurately and it’s usually free.

One detail most people miss: your finger changes size throughout the day. Slimmer in the morning, larger in the evening and in heat. Measure during the day, not right after waking up.

One more thing — the wider the band, the larger the size should be. Worth remembering before you place an order.

Silver reacts to air, sweat, perfume. It darkens, develops a patina. Most people think something went wrong — it’s just a material that’s alive.

You can clean it with a silver polishing cloth or a product made for cleaning silver. If you want to keep the oxidised texture, don’t polish the recesses too aggressively – that’s where the darker colour stays.

You can also leave the patina. It often looks better than polished to a shine — especially in grooves and textures. It gives character.

What to avoid: some chemicals can speed up tarnishing and damage the surface. Take your jewellery off before bathing, swimming and contact with strong chemicals. Creams and perfumes can also speed up changes to the surface of the silver and gold plating.

With stones and ceramic eyes, be careful with ultrasonic cleaners — they can loosen the setting or damage the material.

Over time the raised areas wear and lighten, the darkness stays in the recesses. The ring will look different in a year than it does today. For some that’s a flaw, for me it’s the whole point. Oxidisation can be redone.

Gold plating also wears over time, especially in the areas most exposed to contact. Unlike oxidisation, it is a layer of gold on the surface of the silver. It can be re-plated.

Every piece is made to order. The standard processing time is 7–10 business days.

If the piece is already finished – I’ll ship sooner, often much sooner.

If I need to order a component from the foundry or have it gold-plated, processing may take longer – I’ll let you know before shipping.

Custom orders – I’ll get in touch and we’ll agree on a timeframe.

You’ll get an email when it ships.
