Over time, jewelry is exposed to dust, pollution and daily wear which can cloud the brilliance of gemstones and dull the surface and polish of gold. Certain basic precautions should be taken with all of your jewelry. However, some gemstones, as outlined in this section, require special care. Timeworn prongs and clasps can result in the loss of a stone or an entire piece of jewelry. Professional cleanings are recommended as often as once a year.
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 fractured. Enamel can also chip or scratch when struck. Gemstones can scratch other gemstones and wear away at precious metals. Therefore, avoid stacking rings and bracelets that would be vulnerable to such abrasion. Extreme temperatures, perfumes, cosmetics, ultrasonic cleaning and household chemicals can also damage jewelry.
