Kimaï

Kimaï makes its jewellery exclusively from recycled gold and lab-grown diamonds, which it describes as high quality, lower impact and fully traceable. It is a certified B Corporation and runs stores in London and Paris, alongside the online shop. If you want something built to your own specification, the brand offers a bespoke engagement ring service that you start by booking an appointment.

For European orders the site quotes prices in euros and includes duties for the EU, the UK, the US and the UAE, so a Zurich buyer ordering through it can see the landed cost rather than facing a surprise at delivery. Shipping is global, with signature required on delivery.
