The Foam

The perfect partner to The Tonic, our NEW diamond foam cleanser shows where it goes and stays put to obliterate the grease, oil, dirt and product buildup that diamonds face everyday. Ideal for use in the shower on those diamonds you don't (or can't) take off, or for soaking off caked-on grime. The Foam fights harmful germs and bacteria, is gentle on skin and safe on precious metals and other extra-hard gemstones.  Used with warm-hot water and the juli diamond brush, The Foam rinses completely clean, leaving the surface of your diamonds in pristine condition, free of impurities, with zero trace of sticky, soapy residue. Hyper-concentrated, one pump is all you need. 

Your diamonds are free and clear to twinkle and flash even in low light. 

Not suitable for all jewelry.

  • Perfect For
    Perfect for…cleaning hard-to-remove diamonds while you shower-- jewelry like screw-back studs, box clasp necklaces or screwed-on bangles. Use with the juli diamond brush to clean diamonds set securely into solid precious metal like gold and platinum. The Foam can also be used to clean other extra-hard gems like rubies, sapphires, moissanite, zirconia and lab-grown diamonds. Not suitable for use on pearls, opals, coral, turquoise, or other soft, porous, chemically treated or oiled gems. Do not use The Foam on broken, glued or loosely set jewelry. Always consult your jeweler before cleaning jewelry at home. Juli does not recommend showering in your fine jewelry. View our terms to learn more.

Serious cleaner

Really does work better somehow. Maybe because it's made for diamonds it can be stronger than plain old drug store cleaner? Diamonds just GELAM after using it.
