How to Clean a Diamond, at Home
Warm water. A drop of unscented dish soap. A soft toothbrush. Ninety seconds of gentle scrubbing behind the stone, where lotion and oils collect. Rinse, pat dry with a lint-free cloth. That is the whole ritual. No ammonia, no bleach, no ultrasonic cleaners bought on the internet — they loosen prongs. Do this once a week and your diamond will always look the way it did the day you brought it home.
