The first and only diamond cleanser powerful enough to obliterate the grease, oil, dirt and product buildup that diamonds face everyday. The Tonic 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 Tonic 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.
