What our customers say
“I think I've bought from almost every company on the Czech market, and I have to honestly admit that I truly regret some of those experiences — though that certainly doesn't apply to Mr Auředník, who is incredibly down-to-earth.”
Šárka M.“When I started looking for a lab-grown diamond supplier, I approached 3–4 companies. It was here that won the selection process — through their approach and quick response.”
Martina Vernerová“I appreciate the owner's welcoming approach. The pendant is beautiful. When I have my next big anniversary, I'll happily buy another piece.”
Michal OuškaFrequently asked questions
How do I find out my correct ring size?
Measure the inside diameter of a ring that fits you well, or the circumference of your finger with a piece of thread — then compare it with our size chart (the “How to determine the size?” link next to the size selection). If you're not sure, message us on WhatsApp and we'll be happy to help. The size can also be adjusted free of charge after delivery.
How long does it take to make a piece of jewellery?
Every piece is made to order, exactly to your configuration. Production takes approximately 2–4 weeks. Before dispatch, we will send you photos of the finished piece.
Will I receive a certificate with the diamond?
Yes, we supply an international IGI or GIA certificate with every diamond, confirming its parameters (carat, colour, clarity and cut).
Can I return or exchange the piece?
Yes, you have 30 days to return or exchange it, plus lifetime free servicing of the piece.
What warranty do you offer?

How Mergez Women’s Wedding Ring is made
We make Mergez Women’s Wedding Ring to order, by hand in the Czech Republic - usually within 2 to 4 weeks. Wedding rings are most often ordered in pairs, but each ring in the pair can have a different metal, width and stone setting. Just let us know how you picture the pair.
Metal and surface
The choice is 14K Rose Gold, 14K White Gold, 14K Yellow Gold, 18K Rose Gold, 18K White Gold, 18K Yellow Gold a Platinum. For wedding rings worn every day, 14K gold or platinum works well, as they are more resistant to wear. The surface can be polished, matte or combined; a matte surface better hides small scuffs from everyday wear.
Stones and engraving
The ring for her can be set with diamonds around the band or only at the front, while the ring for him is usually left plain. Engraving a date, name or short message on the inside is free of charge, and we arrange it when you place the order.
Frequently asked questions
Do we order the rings as a pair, or separately?
Whichever you need. Most customers order both at once, but each ring can have a different metal and width. Send us your idea and we will prepare a price for both options.
How do we find out the sizes?
Measure rings that you wear on the same finger and compare them with our size chart. If you are not sure, we will send you sizing rings.
How long does production take?
Usually 2 to 4 weeks from order confirmation. If you have a fixed wedding date, let us know - we will confirm the deadline in advance.
Is engraving included in the price?
Yes, engraving and luxury packaging are free of charge, as is delivery within the Czech Republic and Slovakia.
