Solène Cathedral Solitaire Radiant

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.

Every Kove design is made to order in up to 21 business days — often sooner. The same limit applies to every setting, pavé, halo and hidden-halo included. After dispatch, insured courier delivery within the EU takes 3–7 business days; for Switzerland, customs clearance is added and its length is not known in advance — ask us before ordering.

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.

Yes — Kove ships free insured courier delivery to every country we sell to: the entire European Union (Czech Republic, Slovakia, Germany, Austria, Poland, France, Italy, Spain, the Netherlands, Belgium and all other EU member states), plus the United Kingdom, Switzerland, Norway, the United States, Canada, Australia and the United Arab Emirates. Outside the EU the courier may collect import duties and taxes on delivery — except in Switzerland, where Kove pays them. Every parcel is fully insured at the declared value and ships with signature confirmation.

At Kove, the complete Solène Cathedral Solitaire Radiant (DDLR-094-RA) in 14K white gold starts at €1,286 today — under €1,500, with live pricing for a 1 ct IGI-certified VS1/F lab-grown radiant centre and every other option on the product page. The cathedral solitaire profile lifts the centre stone above the band, maximising light return through the radiant facets.

At 1.5 ct VS1/F, a Kove IGI-certified lab-grown radiant runs about €900–€1,200; a comparable GIA-certified natural radiant runs €4,000–€5,800 — a 75–80% price gap for chemically identical stones. The radiant cut hides minor inclusions better than emerald cuts because of its brilliant-style faceting, so a lab-grown VS2 or SI1 can also work visually with significant additional savings. The Solène Cathedral Solitaire Radiant setting (DDLR-094-RA) accepts both origins at the same setting price.

If her size is unknown, EU 53 (US 6.25) is the statistical median for women in CZ/SK/DACH and the safest default for the Solène Cathedral Solitaire Radiant (DDLR-094-RA). Kove includes one free resize within 60 days of delivery — write to us before sending the ring and we confirm what your design allows: sizing up to +2 sizes is possible on most designs; sizing down depends on the design. You ship the ring to us; the work and insured return shipping within the EU are free. The cathedral solitaire resizes cleanly in both directions because the centre stone sits in raised prongs unaffected by the band adjustment.
