This diamond and jewelry cleaner is recommended for gold, silver, platinum, and most gemstones including tanzanite. It is also safe for water-resistant watches. Can be used daily or weekly.
Not for use on non-metal watch straps, opal, emerald, porous stones (pearl, onyx, turquoise, etc), enameled jewelry, plated jewelry (rhodium is approved), or black oxidized jewelry such as class rings.
The antimicrobial cleaning cloth features soft microfiber suede that is delicate enough for pearls.
