If you want to add powder to ornaments and necklace, I suggest Negative Ion Powder, Type B you ordered (the amount of generating negative ion: 4000～5000p/cm3, D50 grain size: 4～5μm). Because the function and grain size of Type B Negative Ion Powder is sufficient for ornaments, but less than 1μm Negative Ion Powder, Type C generally is used for textile fiber and clothing.
