01The Vision
Precision biometric fine jewelry.
Precise. Personal. Alive.
Lumina is a diamond that senses and interprets your biology. For centuries the diamond has been a quiet witness; Lumina makes it the interpreter. An heirloom that listens. In development, by invitation.
What it is
A category, not a device.
The sensor is the stone. Not attached to it, not hidden beside it, but engineered within the diamond itself.
Who it is for
Luxury and self-knowledge in one object.
Discerning people who already measure what matters: founders, artists, athletes, executives. Attention is their currency, recovery their capital.
How it helps
Readiness, stress, recovery.
The intelligence of a wearable in fine-jewelry form. Real insight into your state, worn as something beautiful.
02The Science
NeuroDiamond™ inside.
NeuroDiamond is the technology at the heart of every Lumina piece: a research programme in diamond-integrated sensing that reads heart-rate variability, pulse dynamics, skin conductance and, in time, deeper markers of nervous-system state.
The stone as sensor.
Nitrogen-vacancy centres and micro-photonic pathways are integrated within the diamond lattice. Invisible to the eye, exquisite to the instrument.
The signal, then the meaning.
Raw biometrics are translated on-piece and paired with an interpretation model that speaks in states rather than numbers.
Anchored in method.
Developed with independent research groups. Claims are anchored in peer-reviewed methodology, not marketing.
Honestly aspirational.
Lumina is in active research and development. We publish what we can measure and stay quiet on what we cannot. No medical claims.

03The NeuroDiamond stack
Seven layers,
named honestly.
Scroll to dismantle the stone into the architecture we are researching, with each layer marked for what is feasible today and what remains hard.
01Feasible now
Diamond + sapphire cap
The optical window — looks like a jewel, works like an aperture.
02Feasible now
Optical PPG sensor
Heart rate, HRV, SpO₂.
03Feasible / emerging
Thermistor + bioimpedance
Temperature, hydration.
04Feasible now
Sensor SoC chip
On-device signal processing.
05The hard part
Battery + inductive charging
Energy density at ring scale — named honestly as the hard part.
06Feasible now
NFC + BLE antenna
Secure data out.
07Feasible now
Titanium housing + soft anchor
Instrument-grade structure against skin.
The intelligence layer
Readiness. Stress. Recovery.
Seven layers of instrument, resolved into a single quiet reading.
04Neuro Sync Engine
Signal into
understanding.
The engine is the interpretation layer: models designed to turn continuous physiological signal into a small number of states a person can act on. It is being built and validated openly, and it makes no medical claims.
- Continuous signal, interpreted on device
- States rather than streams of numbers
- Personal baselines learned over months
05Craft
Five cuts.
Made once. Kept always.
Ethically sourced, GIA-graded diamonds set by master craftspeople in recycled precious metals. Each piece is designed to house the NeuroDiamond sensor without a single visible seam.

06What it measures
The intelligence layer,
rendered in whispers.
A companion application translates the diamond's readings into an understanding of state: never a stream of numbers, always a piece of insight you can act on. Every figure shown on this page is an illustrative sample, not a real reading.
