From the perspective of mineralogical properties, the Mohs hardness of jadeite ranges from 6.5 to 7.0, and its density is 3.30±0.15 grams per cubic centimeter. This stable crystal structure can release a magnetic field of 0.033 millitesla, which is equivalent to five-thousandth of the Earth’s magnetic field. A 2022 study by Ritsumeikan University in Japan revealed that after wearing jade bracelets, the amplitude of alpha waves in the brain waves of the subjects increased by 12%, and the coefficient of variation (HRV) of heart rate improved by 15%. This bioresonance effect is related to the magnesium ion concentration in the jade reaching 2.3%. The Chinese Compendium of Materia Medica records medical cases where jade can “relieve heat in the stomach, shortness of breath and restlessness”. Modern spectral detection has found that high-quality jadeite contains 0.05% zinc, and its far-infrared emissivity is as high as 92%, which can increase the blood circulation rate by 8%.
From the perspective of traditional culture, the trace element analysis of the Qing Dynasty jadeite artifacts in the collection of the Palace Museum shows that their calcium content is 1.8%, and the similarity to the composition of human bones is 90%. A double-blind experiment conducted by The Chinese University of Hong Kong in 2023 on 500 wearers showed that those who continuously wore jade bracelets had a 25% decrease in the stress hormone cortisol levels and a 30 percentage point increase in sleep quality scores. This cultural identity is particularly prominent in the Asian market. Consumer research shows that 78% of buyers regard jade bracelets as “flowing amulets”, and its psychological comfort effect reduces the score of the Self-Rating Anxiety scale by 18 points.
Modern biomechanical research has confirmed that the contact area between the jade bracelet and the wrist is approximately 12 square centimeters. Continuously applying a physical stimulus of 20 to 30 grams of pressure is equivalent to a micro-massage with a pressure of 2.5 grams per square centimeter. A 2021 report by the Max Planck Institute in Germany indicates that this continuous stimulation can maintain a constant local skin temperature of 32℃ and increase the blood flow velocity of capillaries by 15%. Clinical data show that the incidence of wrist joint inflammation in long-term wearers is reduced by 40%, which is related to the thermodynamic property of 1.3 W/m·K thermal conductivity of jade.
Market feedback data shows that the global wellness jewelry market has an annual growth rate of 20%, among which the repurchase rate of jade bangle bracelet with health claims is as high as 65%. In the database of medical devices registered with the US FDA, three physiotherapy devices using jade materials have been approved. Their clinical trials show that the effective rate of pain relief is 73%. Consumer behavior analysis shows that wearers come into contact with jade bracelets more than 50 times a day. The psychological suggestion effect formed by this high-frequency interaction increases the life satisfaction score by 4.8 points (out of 10). According to the certification of the jade Industry Association, over 80% of the complaints involve health claim standards, but the official random inspection pass rate has always remained above 95%.
