Margaux Bezel Stud Round

Yes — a lab-grown diamond is chemically, optically and physically identical to a mined diamond. The only difference is origin: it is grown in a high-pressure / high-temperature or chemical-vapour-deposition reactor over 4–8 weeks instead of mined from the earth. Kove only ships IGI-certified lab-grown diamonds.

Both IGI (International Gemological Institute, Antwerp) and GIA (Gemological Institute of America, Carlsbad) are independent gem labs that grade the 4Cs to identical international standards. IGI is the recognized authority for lab-grown diamonds; GIA is the recognized authority for natural diamonds. Kove ships IGI for every lab-grown stone and GIA (or HRD) for every natural stone over 0.50 ct.

A marquise (or navette) is an elongated football-shape brilliant with two sharp pointed ends — it shows the largest visible surface per carat of any cut and elongates the finger. An oval is a rounded elongated brilliant without pointed ends — it offers similar finger-lengthening with a softer profile and zero risk of point chipping. Both work beautifully for solitaire and halo settings at Kove.

Yes — Kove offers a 48-hour spec-change window after every order. Within that window the metal (14K white / yellow / rose; 18K white / yellow / rose) and center-stone size or shape can be swapped at no charge before manufacturing begins. Reach out via the WhatsApp number on the order confirmation. After 48 hours the configuration is locked because the diamond has been reserved and casting has begun.

Typical production time at Kove depends on the configuration: 10–28 business days for solitaire and three-stone settings, 28–35 business days for pavé, halo and hidden-halo settings with intricate side-stone work. After production we ship insured via courier within 2–7 business days across the EU.

No — the setting price (gold + side stones + labor) is identical, but the center diamond is priced separately and lab-grown diamonds cost roughly 50–70% less than natural diamonds of the same 4C grade. A 2-carat IGI VS1/F lab-grown center retails around €1,200–€1,600 at Kove, while a comparable GIA-graded natural sits at €5,500–€9,000. Both options are offered on every ring with transparent live pricing.

Honestly, no diamond is a good investment — not lab-grown and not mined. Any diamond resells for only a fraction of its retail price (a natural diamond typically around 30–50%), and lab-grown resale is lower and has been trending down as the technology scales. But an engagement ring is an emotional object meant to be worn for a lifetime, not a financial asset to be resold. What never changes is what the independent IGI or GIA certificate guarantees: your stone is a real diamond of the exact grade stated. Choose it for the ring you'll love and wear — not for a resale market.

Your centre diamond comes with its own independent IGI or GIA report — a unique number that is also laser-inscribed on the stone's girdle — so you can confirm it yourself, free: enter the number at igi.org (Report Check) for lab-grown stones or gia.edu (Report Check) for natural stones and compare it on screen with your paper report. On top of that, every finished piece ships with a printed Kove certificate showing the model, its net gold weight and a QR code that opens your stone's official lab report. You never have to take our word for it.
