Ring Sizes, Gold Stamps & Jewelry Care

Soak the item for a few minutes in warm water with a few drops of mild dish soap. Brush gently with a soft toothbrush, rinse in clean water and dry with a soft, lint-free cloth. Avoid chlorine: pool water and household bleach can damage gold alloys over time.

Diamonds attract oil from skin, lotion and soap, which dulls their sparkle. The same warm, soapy water and soft brush works well. Brush behind the stone too, where dirt collects. Do not use an ultrasonic cleaner on diamonds that have been clarity-enhanced (fracture filled), or on any stone you are unsure about.

Emeralds are usually treated with oil, so avoid ultrasonic cleaners, steam and hot water, which can remove the oil. Opals, pearls, turquoise, coral and tanzanite are also sensitive to heat, chemicals or vibration. For these, wipe gently with a soft, damp cloth.

Pearls should be the last thing you put on and the first thing you take off. Put them on after perfume, hairspray and makeup. Wipe them with a soft, damp cloth after wearing. Store pearl strands flat rather than hanging, and have them restrung if the silk stretches or the knots look loose.

Check a watch’s water resistance before swimming or showering with it, and never use the crown or buttons while it is wet. Mechanical watches need servicing every few years; follow the manufacturer’s recommendation.

Store each item separately in a soft pouch or a lined box with compartments. Diamonds and other hard stones can scratch softer stones and metals. Fasten chains before storing them so they don’t tangle, and keep jewelry away from humidity and direct sunlight.

Remove jewelry before swimming, exercising, cleaning with chemicals, gardening or heavy work. It is also a good idea to have a jeweler check the prongs and clasps of items you wear often, so a loose stone is caught before it is lost.
