Cleaning: Between professional cleanings, gold can be maintained by using a soft brush or cloth with a nonabrasive cleaner.
Maintenance: Examine jewelry regularly to make sure settings are snug and clasps and joinings are secure.
Tips: As with all metals, do not wear gold jewelry in swimming pools because the chlorine may cause damage over a period of time.
Other Information: Gold is very soft in its pure form. For example, 24k (pure gold) is softer and less scratch-resistant than 14k and 10k gold.
Cleaning: Use a soft brush and jewelry cleaning solution or warm, soapy water. An ultrasonic cleaner may also by used. Wipe dry with a lint-free soft cloth.
Maintenance: If worn on a regular basis, a diamond should be cleaned at home every 2-3 weeks. And cleaned professionally every 6-9 months. It's also a good idea to have prongs checked for wear or possible loose stones.
Tips: Although diamonds are the hardest known substance, a blow of sufficient force can crack, chip or even break a diamond. Avoid sharp blows and don't wear fine jewelry when doing housework, gardening, playing sports, etc.
Other Information: When storing diamond jewelry, it is a good idea to keep diamonds separated from other stones. This helps avoid scratches on your other jewelry.
Amethyst, Citrine, Garnet, Ruby, Sapphire: Clean with a soft brush and jewelry cleaner or warm, soapy water. Ultrasonic cleaners may also be used, unless the gemstone is treated.

Other Information: Amethyst, aquamarine and citrine all fade or change color after prolonged exposure to the sun.
Cleaning: They may be cleaned gently with a soft brush and lukewarm water, but are best cleaned professionally by a jeweler. It is not recommended to immerse them in cleaning solutions (never wear your emeralds in the bath, shower or when doing dishes), and ultrasonic cleaners should never be used.
Tips: Since treatment is not permanent, it is recommended to have emeralds professionally re-oiled every 1 to 2 years.
Cleaning: You may clean them with a soft brush and warm, soapy water, but never use harsh chemical cleaners or immerse in an ultrasonic cleaner.
Tips: Apply a thin film of light oil with a swab or cloth to the surface of the stone (never soak it) at 6-month intervals to provide an extra measure of protection against dryness and cracking.
Cleaning: Wipe gently with a soft, lint-free cloth after each wearing. Although they are best maintained by professional cleaning, mild soap and water may be used. Dry on a soft, absorbent surface, and never hang to dry.
Tips: Store separately from other jewelry. Do not wear while applying makeup, hair spray and perfumes.
Cleaning: Use a soft brush with warm, soapy water to clean. Avoid the use of ultrasonic cleaners.
