About Lumis

Worn every day.
Not kept for someday.

Most diamond jewellery lives in a drawer. It came out for the wedding, it comes out for anniversaries, and the rest of the year it waits in the dark, too precious to risk. Somewhere along the way, the price of a diamond became the reason not to wear it.

Lumis exists to put diamonds back on. We make a deliberately small collection of lab-grown diamonds set in sterling silver, certified by IGI where the stone is large enough to certify, and priced so that wearing them every day is not an act of courage. The stones are real. The prices are honest. The pieces are for daily life.

Some pieces here will be a first diamond. Some will be a birthday, a graduation, a Tuesday. They go to work, to dinner and to sleep, and they keep up. Nobody needs to wait for an occasion: wearing them is the occasion.

Why Lab-Grown

A diamond the earth didn’t pay for

A diamond in every way

Crystallised carbon, identical to a mined stone in its physical, chemical and optical properties, and graded to the same 4C standards by the International Gemological Institute (IGI).

A traceable origin

Every Lumis diamond begins above ground in a diamond growth facility, never in a mine. No blasting, no displaced earth, and a supply chain traceable to the lab that grew it.

An honest footprint

Growing a diamond takes real energy, and we won’t pretend otherwise. We work only with growers who disclose how their facilities are powered, and we publish what we know, plainly.
