White Black Fashion Ceramic Jewelry Wearable Smart Ceramic Rings
This model of ceramic intelligent wear rings is made from zirconia ceramic with smooth nice surface and the function of waterproof, sweat resistant and breakage proof . Most important , it is equipped with intelligent Sleep control system , GPS system, Heart rate examine and pulse oxygen saturation in blood measuring instrument.
When in the night you are in sound sleep, it can record your status of sleeping , heart rate, pulse beat rate and body temperature to analyze date and give suggestion accordingly.
We can make zirconia ceramic ornaments according to your requirement
1. Hardness close to natural diamond, lighter than the metal, never
wear, never change the color and so on.
2. Wear resistant, oxidation resistant, never rust, never change
color, will not lead the skin allergy.
