The main component of jadeite is sodium aluminosilicate-Aina [Si2O3], which often contains trace elements such as calcium, chromium, nickel, manganese, magnesium and iron. No radioactive elements.

Jewelry and jade include organic matter and inorganic matter, and pearls, corals and rose stones in organic matter are all jewelry. Inorganic substances are minerals and rocks, but not all mineral rocks can be used as jewelry, only more than 200 kinds can be used as gem materials, and none of them are radioactive.

Extended data:

Emerald belongs to pyroxene, monoclinic system and two groups of perfect cleavage. The main component is sodium aluminosilicate NaAl9(Si2O6), and a gem is regarded as jadeite only if it contains more than 50% sodium aluminosilicate. It occurs in metamorphic rocks generated at low temperature and high pressure.

It often coexists with glaucophane, muscovite, andalusite (anorthite dihydrate), aragonite and Yingshi. Mohs hardness is 6.5-7, specific gravity is 3.25-3.35, and melting point is 900- 1000℃

Most of the high-quality jadeites in the jewelry market come from the Quaternary and Tertiary conglomerate layered jadeite deposits in the Ulu River (River) basin in northern Myanmar. Jadeite rock is mainly composed of white jadeite with various green tones, brownish yellow and light purple. In addition to jadeite minerals, there are diopside, amphibole, aegirine and albite, and few green jadeites reach the gem level.
