About the piece
The Antares engagement ring is a striking design with a round centre stone in a six-claw setting and a band richly set with diamonds in three rows of 3D micro-pavé. Sparkle from every angle. It pairs with the Antares wedding ring.
The centre diamond – lab-grown or natural – is selected directly with the piece; the price shown is without the stone. On request, we can adjust the piece to your specification – for example the diamond size, cut or other details. Engraving is free of charge; you provide the text directly with your order.
- Side diamonds
- 3D micro pavé in three rows, E-F / VVS-VS
We will tailor the piece to your wishes. On request, we can set any other diamond shape or size into it and adjust the design to your specifications – just drop us a message.

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?
We provide a warranty on jewellery and diamonds in accordance with the terms and conditions of ULTIMATE-GEMS s. r. o. We also supply an IGI or GIA certificate with every certified diamond.
Can I have a different diamond shape or size set into the piece?
Yes. On request, we can set any other diamond shape or size into the piece and tailor it to your wishes. Message us on WhatsApp or by email and we will prepare a quote.
How much does delivery cost?
Delivery across Europe by GLS costs 30 EUR (free within the Czech Republic and Slovakia). The parcel is always insured and your piece arrives in elegant gift packaging.
