First of all, quartzite jade is a kind of natural jade, which has no radiation, but contains some trace elements beneficial to human body. Wearing quartzite jade for a long time can promote human health and enhance human immunity and resistance.

Secondly, the artificial imitations of quartzite jade are mostly made of glass and other materials. This imitation is usually harmless and can be worn safely. However, some quartzite jade synthesized with dyes may have adverse effects on human body. This is because dyes may cause irritation to human skin, and long-term wear may also lead to oxidation reaction on the surface, affecting human health.

So generally speaking, quartzite jade is harmless to the body and can be worn for a long time. However, when buying and wearing, it is best to choose natural products that have not been treated with dyes to ensure their safety.
