DNA jewellery is a type of personalised jewellery created using your unique genetic profile. A DNA sample — typically taken via a simple cheek swab — is processed in a laboratory to extract a DNA profile. That profile is then translated into a physical design, resulting in a piece of jewellery that is scientifically guaranteed to be one of a kind.
At DesigNA, we combine advanced genetic analysis with skilled jewellery craftsmanship to create bespoke necklaces that represent your unique genetic blueprint. No two profiles — and no two pieces — are ever the same.
How Does DNA Jewellery Work?
The process begins with a DNA sample. You receive a cheek swab kit, which you use at home and post back. The sample is sent to our UKAS-accredited laboratory, where your DNA is extracted and profiled using a technique called gel electrophoresis — the same method used in forensic science and medical genetics.
Your DNA profile produces a unique pattern of bands and markers. Our designers translate this pattern into a physical arrangement of semi-precious stones and sterling silver or gold beads, each placed according to the data in your profile. The result is a necklace that is not just personalised by name or initials — it is personalised at the molecular level.
You can learn more about the full process on our How It Works page.
What Makes DNA Jewellery Different from Other Personalised Jewellery?
Most personalised jewellery is customised by the buyer — a name engraved, a birthstone chosen, a date stamped. DNA jewellery is different because the design is determined entirely by your biology. You do not choose the arrangement. Your genes do.
This means every DesigNA necklace is a true 1-of-1. Even identical twins have slightly different DNA profiles due to epigenetic variation, meaning even they would receive different designs.
What is the Science Behind It?
The science behind DNA jewellery is rooted in DNA profiling, also known as genetic fingerprinting. First developed by Professor Sir Alec Jeffreys at the University of Leicester in 1984, DNA profiling analyses specific regions of your genome — called STR (Short Tandem Repeat) loci — that vary significantly between individuals.
The probability of two unrelated individuals sharing the same DNA profile across multiple STR loci is less than one in a billion. This is the same science used in criminal forensics and paternity testing. At DesigNA, we harness this technology not for identification purposes, but to create something beautiful.

Is DNA Jewellery Safe?
Yes. The DNA extraction process is entirely non-invasive — it requires only a painless cheek swab. No blood or tissue samples are needed. The sample is processed in a certified laboratory under strict data protection and privacy protocols.
DesigNA takes DNA privacy extremely seriously. Your genetic data is used solely to create your jewellery design and is never sold, shared, or stored beyond what is required. You can read our full DNA privacy policy for complete details.
Who is DNA Jewellery For?
DNA jewellery makes an exceptional gift for someone who already has everything — a truly unique, unrepeatable piece that cannot be bought off a shelf. It is popular for:
- Mothers and grandmothers — your DNA is a literal piece of your child
- Romantic partners — carry your partner’s genetic fingerprint with you
- Yourself — a celebration of your own identity
- Science enthusiasts who appreciate the technology behind the design
- Anyone who values truly one-of-a-kind craftsmanship
How Much Does DNA Jewellery Cost?
DesigNA DNA necklaces start from £220 for a sterling silver piece. Gold and pearl variants are also available. Given that each piece requires laboratory DNA analysis, skilled hand-crafting, and is guaranteed unique, the price reflects the science, craftsmanship, and exclusivity involved.

Frequently Asked Questions About DNA Jewellery
How long does it take to make DNA jewellery?
From receiving your DNA sample, DesigNA typically takes 4–6 weeks to complete the laboratory analysis and handcraft your necklace.
Can I order DNA jewellery as a gift without telling the recipient?
Yes. You provide the DNA sample (with the recipient’s consent), and we create and deliver the necklace as a surprise gift. Our consent page explains the process in full.
What happens to my DNA sample after the jewellery is made?
Your DNA sample is securely destroyed after the profiling is complete. DesigNA does not retain raw genetic material. Your privacy is our priority.
