A ring becomes more than a ring when the pattern is literally yours.
“Crafted By My Heart” is an app launched by DDB Group Hong Kong that lets you customize jewelry with your own heartbeat. You place a finger over the smartphone’s camera and flash. The app detects subtle changes in finger coloration, measures your heartbeat, then translates its intensity and rhythm into a unique digital rendering. That rendering becomes the basis for a one-of-a-kind ring.
The idea in one line
Turn biometric signal into a personal design language, then manufacture it as a physical object.
How the experience works
The flow is intentionally simple.
- Capture
You use the phone’s flash and camera to read your heartbeat through small changes in skin coloration. - Translate
The heartbeat becomes a digital rendering that is unique to your rhythm. - Craft
That rendering is used to create a ring. It is not a generic engraving. It is a form generated by your own signal.
The product choices are clear and bounded
The app offers two base designs, Surge and Sierra, with three finishes: gold, silver, or black silver. Rings cost between HK$1,198 and HK$1,588 (listed as US$155 to US$205), and take around 15 to 20 working days to complete.
Why this works as innovation, not just novelty
Personalization is structural, not cosmetic
A lot of customization is color, text, or surface. Here, the customer input generates the form. That feels materially more personal.
Technology removes the intimidation barrier
Biometrics and jewelry-making sound complex. The interaction is not. One finger. One phone. A result you can explain in one sentence.
The story is built-in
The product carries a narrative you can repeat instantly. It is your heartbeat, turned into a physical object. That makes it inherently giftable.
The deeper point
When brands look for meaningful personalization, the win is rarely “more options.” The win is finding a signal that matters emotionally, translating it into a design system, and making the creation process easy enough that people actually do it.
A few fast answers before you act
What is the core mechanic behind Crafted By My Heart?
The phone’s camera and flash detect heartbeat via subtle changes in finger coloration, then translate the rhythm into a digital rendering used to craft a ring.
What does the customer actually customize?
They select a base design and finish. The unique part is the heartbeat-generated rendering that drives the final piece.
What are the available designs and finishes?
Two base designs. Surge and Sierra. Three finishes. Gold, silver, and black silver.
What are the price and production timelines?
HK$1,198 to HK$1,588 (US$155 to US$205). Around 15 to 20 working days.
What is the transferable lesson for other categories?
If you can capture a personal signal that people care about, translate it into a design language, and make ordering effortless, you turn “customization” into meaning.
