What we make
LUMÉRA is a fine jewellery house working exclusively in laboratory-grown diamonds and laboratory-created coloured gemstones. Every piece is set in solid precious metal and cut to the same standards applied to mined stones — because they are, materially, the same stones.
We say this plainly on every product page, on every invoice, and in our Terms of Service. A laboratory-grown diamond has the identical chemical, physical and optical properties as one pulled out of the ground. It is not an imitation. It is also not a mined diamond, and we will never let that distinction blur.
Why laboratory-grown
A mined carat carries a long chain of cost that has nothing to do with the stone in your hand — extraction, certification layers, wholesale tiers, and a retail markup built for a showroom with rent to pay. Growing the same crystal in a reactor removes most of that chain.
What is left is the part that actually matters: the cut, the setting, the finish. That is where we spend.

How we describe our stones
Jewellery is an industry where vague language does a lot of work. We have taken a deliberately narrow line:
- Every laboratory-grown or laboratory-created stone is labelled as such, in full, in English — following the US FTC Jewelry Guides (16 CFR Part 23) and CIBJO Blue Book conventions.
- Moissanite is called moissanite. It is a beautiful stone and it is not a diamond.
- Cubic zirconia is called a simulant, because that is what it is.
- We publish grading only where a laboratory has actually issued it. We do not assign colour or clarity grades ourselves, and we do not quote a grade that is not on the certificate in front of us.
- Where a piece contains a natural stone, we say so on the product page.
The standard we hold ourselves to
- 30 days to change your mind — how returns work
- 12 months against manufacturing defects
- One free resize, because a ring that does not fit is not a ring
- Insured, tracked shipping on every order, worldwide
- A reply within 2 business days, from a person — write to us
