Jade has no radiation, jewelry jade is not radioactive
The main component of jade is: sodium aluminum silicate - NaAI [Si2 O6], often containing Ca, Cr, Ni, Mn, Mg, Fe and other trace elements. Does not have radioactive elements.
Jewelry and jade include organic and inorganic, organic matter in the pearl, coral, jewel beat, etc. are jewelry. Inorganic for minerals, rocks, but not all minerals and rocks can be used to make jewelry, only more than two hundred kinds of materials can be made for jewelry, none of them are radioactive hazards.
Expanded information:
Jadeite belongs to the pyroxene class, monoclinic crystal system, two groups of complete solution. The main constituent is sodium aluminum silicate NaAl9 (Si2O6), gemstone ore contains more than 50% more sodium aluminum silicate is considered jadeite), produced in the low temperature and high pressure generated in the metamorphic rock layer.
Often accompanied by blue amphibole, muscovite, stibnite (calcium feldspar dihydrate), aragonite and quartz. It has a Mohs hardness of 6.5-7, a specific gravity of 3.25-3.35, and a melting point between 900-1000°C. It has a hardness of 6.5-7, a specific gravity of 3.25-3.35, and a melting point between 900-1000°C.
Most of the high-quality jadeite on the jewelry market comes from the Quaternary and Tertiary conglomerate layered jadeite deposits in the Misty Dew River (River) Basin in northern Myanmar. Jadeite rock is mainly white and scattered with a variety of green shades and brownish-yellow, light purple stibnite composition, in addition to stibnite minerals in addition to diopside, hornblende, nepheline and sodium feldspar and other minerals, to reach the gemstone grade green jadeite is rare.
