If you have come across DNA jewellery and want to understand what actually happens, this is the plain answer. No jargon, just the process from start to finish, and what it means for what ends up around your neck.

What Is a DNA Necklace?
A DNA necklace is a piece of fine jewellery that comes directly from your genetic profile. Of course, your DNA is unique to you. In fact, every person on earth carries a different sequence of genetic markers, so a DNA necklace takes that pattern and turns it into something you can wear.
At DesigNA we call it the exact DesigNA necklace, because that is exactly what it is. Your profile. Your sequence. Made by hand in the United Kingdom.
To understand what makes your DNA unique, read Your DNA Is Unique. Here Is What That Actually Means.
Step One. Your Sampling Kit Arrives
After you place your order, DesigNA sends a sampling kit to your address. Inside you will find a cheek swab, simple instructions, and an addressed return envelope. You need no specialist knowledge, no clinic visit, and no blood sample.
First, you swab the inside of your cheek for around 60 seconds. Then you seal the sample and post it back. That is the full extent of your involvement in the scientific part.
Step Two. A Specialist Profiles Your DNA
Once the laboratory receives your sample, a specialist analyses it and identifies your unique genetic markers. In short, these are the sequences that make you genetically distinct from every other person alive.
The result is a pattern. In other words, a visual representation of something that has always existed inside you, now made visible and ready to become permanent.
Step Three. A Jeweller Makes Your Necklace by Hand
Next, DesigNA passes your genetic profile to its partner jeweller in Birmingham, who translates it into a handcrafted necklace. Your piece is made in the material you ordered:
- Silver. 925 sterling silver.
- Gold. 9ct gold with gold filled spacers.
- Pearl. Genuine freshwater pearls with sterling silver and semi precious stone markers.
Because each piece is made to order, there is no production line. A jeweller makes the necklace from your profile once, for you, and never makes it again.
Step Four. Your Necklace Arrives
Finally, once the piece is complete, DesigNA packages it and sends it to you. Throughout, the team keeps you informed, from kit received to jewellery dispatched. The kit reaches you in 2 to 3 working days, and your finished piece is sent 2 to 3 weeks after your sample arrives at the laboratory.
What Happens in the Laboratory
The laboratory extracts DNA from the cells on your swab, then copies specific short sections many times over so they can be measured accurately. It reads short tandem repeats: stretches of DNA where a short sequence repeats a different number of times from one person to the next.
Those readings are made with five fluorescent dyes, and each dye is given its own stone on your piece. So the colours along the strand, and where each one falls, come from your reading rather than from anyone's choice. The laboratory has over 25 years in genetic testing.
How Your Piece Arrives
Your piece comes in layered packaging: an outer black box holding your certificate of authenticity, a blue sleeve, then the inner black jewellery box, with a necklace laid out in a double helix.
Is It Safe? Is My DNA Data Private?
DesigNA handles your genetic data with full GDPR compliance, because it treats your DNA as the sensitive personal information it is. The finished piece is jewellery, not a biological material, so it is entirely safe to wear. For context, the UK Information Commissioner explains special category data and why genetic information deserves this care.

Frequently Asked Questions
How does a DNA necklace work?
A DNA necklace works by profiling your unique genetic code from a cheek swab, then translating that profile into a handcrafted piece of jewellery. At DesigNA, your sample goes to a specialist laboratory, where a scientist maps your DNA. A jeweller in Birmingham then makes your necklace by hand from the resulting pattern. Because no two people share the same genetic profile, no two DNA necklaces are ever the same.
What sample is needed to make a DNA necklace?
A simple cheek swab is all you need. First, DesigNA sends the swab in a sampling kit by post. Then you swab the inside of your cheek at home for about 60 seconds, seal the sample, and return it in the addressed envelope. Importantly, there is no blood sample, no clinic visit, and no specialist knowledge required.
How long does a DNA necklace take to arrive?
The kit reaches you in 2 to 3 working days. Once your sample arrives at the laboratory, your finished piece is sent within 2 to 3 weeks, covering the profiling, the handmaking and the dispatch.
Is my DNA data kept private?
Yes. DesigNA handles all genetic data in full compliance with GDPR. It uses your DNA sample solely to create your necklace profile and treats it as sensitive personal information under UK data protection law. For the full details, read our Is DNA Jewellery Safe? article.
What materials are DNA necklaces made from at DesigNA?
DesigNA offers three materials: 925 sterling silver, 9ct gold with gold filled spacers, and freshwater pearl with sterling silver. A partner jeweller in Birmingham handmakes all of them in the UK. Necklace prices start from £249.
Your genetic code, profiled from a simple cheek swab and handcrafted into the exact DesigNA necklace. No two are ever the same.
