Pure Silver is also referred to as 999 Fine Silver and not to be confused with 925 Sterling Silver.
999 Fine Silver contains 99.9% Silver, with the balance being trace amounts of impurities. Any silver used for investment or trade on metal
and commodities exchanges must be 99.9% Pure, or 0.999, sometimes referred to as “Three Nines Fine.”
Investment grade fine silver is stamped with a Hallmark certifying its purity.
999 Fine Silver is reserved for Bullion Investment Products; it is generally considered too soft for industrial, commercial, or jewelry use.
Sterling silver used in jewelry, for example, has a purity of 92.5 percent. Thus, silver jewelry is often stamped with 925.
