The benefits of an expert's assistance when purchasing diamond jewellery

diamond

Your expert jeweller knows the value of diamonds best

Whether it's a diamond ring, a necklace with a diamond pendant, earrings or a bracelet with diamonds, a professional recognises the value of each piece. BAUNAT guides you with precision in the purchase of diamond jewellery and inform you about the quality, colour and purity of the diamond as well as the precious metals used.

An expert knows everyone's taste best

If you doubt the choice of a ring for your future wife, a necklace for your wife or a bracelet for your mother, an expert will recommend a model that will suit her best. During your appointment with the BAUNAT expert team, they will advise you in detail on each jewellery item and answer all your questions.

Design & buy with BAUNAT: step-by-step

1. Discovery and brief

The process starts with a short conversation to clarify style preferences, reference designs and practical details such as ring size and daily wear. For remote clients this can take place by video call or through detailed questions and photos, which lets our experts propose suitable styles without an immediate showroom visit.

2. Selection or custom design

Based on the brief, we present curated ready-made options or a custom proposal. For bespoke rings our designers turn your preferences into sketches and 3D previews. Remote customers receive high-resolution images and virtual views so they can assess proportions and finish before any work begins.

3. Diamond selection and technical checks

Every suggested diamond is picked according to the agreed criteria for cut, colour and clarity and comes with its gemmological certificate. Our experts perform additional checks to confirm proportions and optical performance, ensuring the stone meets both aesthetic and technical expectations.

4. Approval and craftsmanship

Once the design and stone are approved, our Antwerp workshop begins production under strict quality controls. Customers receive confirmation of the chosen specifications and the certification that will accompany the finished piece.

5. Finalisation and delivery

Before the piece leaves our workshop it undergoes a final inspection to confirm finish and setting security. Remote buyers receive detailed photos and documentation prior to shipment and our team remains available for any follow-up questions.

Your expert will help you to determine the right size

It can sometimes be difficult to know the right size of your jewellery. Especially with a diamond ring, such as an engagement ring, you want to have the right size right away. BAUNAT's experts can easily help you with this, even remotely. You can order our ring sizer to find your right ring size at home.

An expert only sells professionally certified jewellery

An authentic diamond should always be accompanied by a gemmological certificate;

  • First of all, because a certificate provides detailed information about the jewellery and allows you to identify the jewellery exactly

  • Secondly, because the gemmological certificate guarantees the authenticity and quality of the chosen diamond

If you buy your diamond jewellery from an expert, she will also accurately clarify all the properties mentioned in the certificate, such as the size, colour and purity of the diamond.

Payment, protection and craftsmanship assurances

We know choosing fine diamond jewellery combines emotion with practical concerns. To give you confidence in your purchase, BAUNAT provides clear information about payment options, product protection and the quality of our workmanship.

Payment options and alternatives

We accept common secure online payment methods. If you prefer an alternative arrangement or want to discuss financing options, contact our team so we can look at suitable solutions together.

Protection and workmanship assurance


  • Every piece bought from BAUNAT is covered by a workmanship assurance that protects against manufacturing defects. The full terms and scope of this assurance are provided with your purchase documentation.

  • For extra peace of mind, BAUNAT can explain protection options that cover loss, damage and routine care. Our advisors will describe what each option includes so you can choose what fits your needs.


What professionally certified means for you

  • A gemmological certificate lists the diamond’s measured characteristics and provides independent verification of authenticity and quality. This certificate creates a clear, third-party record of the stone’s properties.

  • Our experts review and explain every certificate so you understand what has been tested and why those details matter for appearance, durability and potential resale value.
