Frequently asked questions
Is a lab-grown diamond a real diamond?
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.
How does an IGI certificate differ from a GIA certificate?
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.
What's the difference between a marquise and an oval cut?
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.
Can I change the metal or stone shape after ordering?
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.
How long does production take?
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.
Is the price the same for lab-grown and natural diamonds?
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.
Do you ship internationally?
Yes — Kove ships free insured courier delivery to the entire European Union (Czech Republic, Slovakia, Germany, Austria, Poland, France, Italy, Spain, the Netherlands, Belgium and all other EU member states). Delivery outside the EU is available on request and quoted individually. Every parcel is fully insured at the declared value and ships with signature confirmation.
