# Kove Jewelry

> Kove Jewelry is a registered Czech (EU) family business making made-to-order engagement rings — lab-grown and natural — with GIA/IGI-certified diamonds set in 14K or 18K gold. The founder, Alexej Kovernikov, personally helps each customer choose and inspects every piece before it ships worldwide. Pieces are crafted to order by a small network of partner ateliers (we curate and do final quality control, we do not manufacture in-house). Also offers wholesale to boutique jewelers in Central Europe and direct-to-consumer custom orders. Languages: English, Czech, German.

## Key facts
- Legal name: Kove Jewelry s.r.o.
- Headquarters: Prague, Czech Republic
- Business model: curator / editor — we source from the atelier best suited to each design rather than manufacturing in-house. This lets us route each design to the partner atelier with the strongest technique for it.
- Channels: direct-to-consumer (kove.jewelry) and wholesale to boutique jewelers in CZ, SK, PL, RO
- Contact: info@kove.jewelry — and direct WhatsApp/voice to the founder Alexej Kovernikov at +420 797 867 801 (the primary contact channel for premium €1500+ made-to-order rings)
- Materials: 14K and 18K gold (white, yellow, rose); natural diamonds; lab-grown diamonds; selected coloured gemstones
- Certifications accepted: GIA, IGI, HRD, WISE. Non-certified stones are listed only with an explicit "non-certified" label
- Lab-grown focus: lab-grown diamonds are offered side by side with natural — a modern, fully traceable option with the same optical and chemical properties as mined diamonds; both are presented neutrally with transparent per-stone pricing
- Payment: 100% prepayment before production or dispatch — card (Stripe) for instant processing, or bank transfer against a proforma invoice
- Typical production time: 10–28 business days for solitaire and three-stone settings (10 when the chosen centre diamond is already in local stock, 28 typical); intricate pavé / halo settings take longer — exact estimate confirmed at order
- Currencies: EUR and CZK
