The Angel
The Gem
An 18mm flat cabochon that looks like a precious gemstone and works like a personal witness. Visible gold circuitry under rose-cut facets. Body-heat powered. Magnetically mounted. No charging, no clips, no clasps. Just snap and go.


Inside the crystal
What's Inside
CMOS camera, BLE 5.4 radio, gold-trace flex PCB, RGB LED indicator, piezo transducer, N52 neodymium magnet ring, and inductive charging coil — all fully encapsulated in optically clear UV-cure resin with faceted rose-cut geometry. No exposed contacts. No seams. No screws.
The manufacturing process uses the device's own internal piezoelectric transducer to perform ultrasonic degassing during resin curing — a patented technique that produces gemstone-grade optical clarity.

Design variants
Crystal. Stealth. Sport.
Three design variants, one architecture. Crystal is transparent with visible gold traces — the signature look. Stealth is matte black for covert carry. Sport is ruggedized with high-visibility housing for outdoor and tactical use.
All three share identical internals. The Gem is the Gem — only the shell changes.

Magnetic ecosystem
One Gem. Many Mounts.
Snap the Gem onto any mount magnetically. No pogo pins, no clips. Every mount charges the Gem through inductive coupling. Some harvest body heat. Some collect DNA. All of them look like jewelry.

7 patented architectures
Powered by You
Seven distinct thermoelectric generator architectures — from doped graphene/h-BN superlattices to M13 bacteriophage bio-hybrid generators — covered by 30 patent claims. The system harvests electrical energy from the temperature differential between your skin and ambient air.
The same traces that generate power also sense your biometrics: heart rate, skin temperature, galvanic skin response, respiration rate, and blood oxygen. Dual-purpose by design.
