The Science Behind Your Jewellery
Every DesigNA piece is created from your unique genetic fingerprint — the same technology trusted by forensic scientists worldwide.
What is STR Analysis?
STR stands for Short Tandem Repeat — a section of your DNA where a short sequence of base pairs repeats over and over.
The number of times these sequences repeat is unique to you, creating a pattern as individual as a fingerprint. It’s the same analysis used by forensic scientists in criminal investigations, the NHS for paternity testing, and intelligence agencies worldwide.
In short: STR analysis is the gold standard for personal identification — and it’s what makes your DesigNA piece truly yours and no one else’s.
Why Not an Ancestry or Health DNA Test?
Most consumer DNA tests (like 23andMe or AncestryDNA) analyse SNPs — single nucleotide polymorphisms — to predict your heritage or health risks. DesigNA deliberately does not do this.
| Ancestry/Health Tests | DesigNA (STR) | |
|---|---|---|
| What it reads | Health & ancestry markers | Identity markers only |
| Health information revealed | Yes | None |
| Ancestry revealed | Yes | None |
| Used in forensics | No | Yes |
| Uniqueness | Shared with relatives | Unique to you |
We chose STR analysis specifically because it tells us who you are — not what you are. Your health, your heritage, your predispositions: none of that is captured. Just the beautiful, unique numerical pattern that makes you, you.

From DNA to Design: How It Works
Your Swab Kit Arrives
We send a sterile cheek swab kit straight to your door. The collection process takes under two minutes — simply swab the inside of your cheek and return it in the prepaid envelope.
Laboratory STR Profiling
Your sample is processed at our accredited partner laboratory. Using capillary electrophoresis, scientists identify the repeat count at each of 16+ STR loci across your genome. This produces a string of numbers — your unique genetic profile.
Your Profile Becomes Art
Our design team translates your numerical STR profile into a visual pattern — a rhythm of peaks and valleys as unique as your DNA. This pattern is then applied to your chosen piece of jewellery.
Handcrafted & Delivered
Your piece is handcrafted to the highest standard and delivered in beautiful DesigNA packaging — a one-of-a-kind creation that can only ever belong to you.
Your DNA is Safe With Us

🔬 STR Only
We extract only your STR profile — the identity numbers. No health, ancestry, or predisposition data is ever read or stored.
🔒 Sample Destroyed
Your physical DNA sample is destroyed after profiling. We do not retain, sell, or share your raw genetic material with any third party.
🏛️ UK GDPR Compliant
All data is handled in accordance with UK GDPR. Your STR profile numbers are stored securely and used solely to produce your jewellery.
🗑️ Right to Erasure
You can request the deletion of your STR profile data at any time, simply by contacting us at sales@mydesigna.co.uk.
