Drawing on know-how passed down from father to son for six generations, the diamond experts of Maison Laveran have created a collection of lab-grown diamond fine jewelry in their own image: refined, with delicate details, made from ethical materials.
Lab-grown diamond jewelry: the brilliance of a diamond, without compromise
A lab-grown diamond is a real diamond: crystallized carbon with the same hardness, brilliance and fire as a mined stone. Only its origin differs. Grown in a few weeks using HPHT or CVD processes, it is certified by the independent laboratories IGI and GIA. You may also come across the terms “lab-created diamond”, “lab diamonds” or “man-made diamond”: they all refer to the same stone, not to be confused with imitations such as cubic zirconia.
A full eternity band is set with diamonds around its entire circumference, for maximum brilliance; a half-eternity band is set only across the visible half — more discreet, more comfortable to wear and more accessible. Both are available in our collections.
A slim band (1.5 to 2 mm) stays discreet and pairs well with a solitaire; a width of 2.5 to 3.5 mm gives the diamonds a stronger presence. Our experts advise you in the showroom based on your engagement ring and the shape of your hand.
Yes: we design our wedding bands to pair perfectly with our solitaires (same metal, same setting style). You can also compose a bespoke set in our workshop.
Yes. Physically, chemically and optically identical to a mined diamond, it is certified by the same independent laboratories, IGI and GIA.
Every wedding band is available in 18k white, yellow or rose gold and in platinum. Use the metal preview to visualize the result, and ideally match it to the metal of your engagement ring.
Collection pieces ship within a few business days; a bespoke creation takes 2 to 4 weeks. Complimentary insured delivery, and complimentary resizing for life.
In a showroom or by video call, an expert takes in your story, your wishes and your budget — without ever rushing you.

Frequently asked questions about lab-grown diamonds
Yes. It is crystallized carbon, exactly like a mined diamond: same hardness, same brilliance, same fire. Only its origin differs.
Only in its origin: one formed underground over millions of years, the other is grown in a few weeks. To the eye and under a loupe they are indistinguishable — but the lab-grown diamond is more ethical and more accessible.
Using two processes: HPHT (high pressure, high temperature) and CVD (chemical vapor deposition). Both produce real diamonds from a carbon seed.
Yes, it is a certified precious stone. Its price is 30 to 70% lower than an equivalent natural diamond, which means a larger or purer stone for the same budget.
It is impossible with the naked eye or a standard microscope. Only specially equipped laboratories (IGI, GIA) can identify it. Every certified stone bears a laser micro-inscription and a certificate number.
It depends on the 4Cs. At Laveran, a solitaire ring starts at around €880. At equal carat and quality, it costs significantly less than a natural diamond.
Yes, every Laveran diamond is delivered with its IGI or GIA certificate, precisely attesting to its 4Cs.
Warm soapy water, a soft brush, a rinse and a soft cloth. Avoid chemicals and have the setting checked once a year.
