Certain basic precautions should be taken with all of your jewelry. However, some gemstones, as outlined in this section, require special care.
Take care to protect your jewelry from impact against hard surfaces and avoid contact with abrasive surfaces. Even a diamond can chip if hit with enough force or at just the right angle. Many stones such as amethyst, emerald, kunzite, opal, pearl, peridot, tanzanite and tourmaline are very delicate and easily abraded. Enamel can also chip or scratch when struck. Gemstones can scratch other gemstones and wear away at precious metals. Therefore, avoid stacking those rings and bracelets that would be vulnerable to such abrasion. Extreme temperatures, perfumes, cosmetics, ultrasonic cleaning and household chemicals can also damage jewelry.
To clean diamonds, use a mild solution of six parts water to one part ammonia and apply with a soft bristle brush.
If worn often, pearls should be cleaned and restrung professionally once a year. Between cleanings, wipe pearls gently with a damp cloth.
Gold and Platinum
Between professional servicing, most gold and platinum jewelry can be maintained with a non-abrasive cleaner. Examine your jewelry regularly to make sure settings are snug and clasps and joinings are secure.
Avoid exposing gold jewelry to household bleach, which will quickly cause gold to discolor and possibly disintegrate.
Jewelry storage is important as well. At the time of purchase, all jewelry is wrapped in a protective box, case or tarnish-resistant pouch. Between wearings, we recommend that you place it back in its original case or another suitably lined box or pouch.
The jewelries should be worn after you finished your makeup and body care or wearing perfume. Your makeup could make the jewelries dull and dirty. And some chemical ingredients in your beauty products could effect the gold settings.
