Per Good Housekeeping Magazine (its on my desk), Harry Winstow (the FAMOUS Jewler) mixes 2 parts hot tap water and one part amonia. Soak diamonds (only good for diamonds as mixture may hurt other jewels) for several minutes. While submerged, scrub with soft makeup brush or baby's toothbrush. Rinse with warm water and pat dry. Repeat monthly or as needed.
