Micro-crystal Zr ceramics
JAKCOM R4 whole body is entirely made of micro-crystal Zr ceramics.
With excellent refractive index and chromatic dispersion, the device emits unique rounded luster.
Each ring needs to undergo forging for 2 days, sintering in a 1400 ℃ furnace for 5 days, thousand times of CNC polishing, coating and other post-procedures.
It takes 35 days to present the ring in front of you.
By virtue of the low thermal conductivity of Micro-crystal Zr ceramics, JAKCOM R4 has a gentle touch sense as jade.
