Even a small amount of grease or oil can dramatically dull the brilliance of your diamonds. This is why it is important to clean your diamond jewelry regularly, advises Philip Press, president and chief executive officer of Renaissance Platinum (see video below).
"I find the easiest way is to either use a specialized jewerly cleaner or a straight clear, ammonia," says Press. "Let the piece of jewelry soak in the solution for an hour or more. Use an old toothbrush and clean the sides and bottom of the diamond and then rinse it very well under hot water. Don't be afraid of over cleaning your diamonds." Be sure to be gentle with the brush, however, as diamonds can become loose from their settings if they are treated roughly.
A few words of warning: Jewelry should not be cleaned in or near the sink. If there is no better location for the cleaning, be sure the plug is in, to avoid the jewelry going down the drain.
Also, it is very important that you to store your diamond jewelry separately, such as in individual compartments or pouches so they do not touch other gemstones. "Because a diamond can scratch another diamond," advises Press. "It is even more important to keep your diamond jewelry separated from your other gemstone jewelry because diamonds will certainly scratch other gemstones."
