Like diamonds, red (blue) gems, cat's eyes, crystals, emeralds, zircon, tourmalines, and jadeites, such as jadeite, nephrite (Hetian jade), pearls, corals and amber. These natural minerals and rocks do not contain too many radioactive elements and will not affect human health. Moreover, wearing precious stones is good for your health, such as crystal and tourmaline. Crystal has piezoelectric effect. Wearing crystal ornaments can produce a weak electromagnetic field, which can stabilize emotions and enhance people's resilience. Tourmaline, also known as tourmaline, has piezoelectricity and pyroelectricity, which can produce negative ions to adjust the balance of the body and resonate with the body, thus making various physiological functions work in harmony. Wearing gems for a long time can make some beneficial trace elements penetrate into the human body and play a health care role.
Although most natural gemstones have little impact on human health, two associate researchers warned that individual natural gemstones, such as natural low-grade green zircon and artificially irradiated color-changing gemstones, such as topaz (or topaz), will be radioactive if they have no half-life, which will cause harm to human body. Therefore, you must go to a regular store to buy jewelry, and it is best not to wear radioactive jewelry.
