Keep jewelry away from chemicals

Exposure to chemicals may damage or discolor precious metals (gold, silver and platinum) and may also cause damage to certain colored stones. Even everyday household products like hairspray, lotions, perfumes or other cosmetics contain chemicals that can permanently damage the surface of jewelry and other delicate or porous stones (such as Turkish stones). Always remove fine jewelry before diving into a pool that contains chlorine or using household cleaners. Many of these cleaners contain ammonia, which is too harsh for delicate stones or antique jewelry. Chlorine bleach is another common household solvent that can cause dents or damage to gold alloys.

Beware of light and heat

Just as the sun’s harmful rays can harm our skin, light and heat can affect the durability and color of colored gemstones. Over time and from excessive light and heat, certain stones can also fade and become damaged, such as amethyst, lithium amethyst, topaz and shell cameo. Pearls and other fine materials (such as ivory) can be bleached if they are overexposed to light. Other stones, especially amber, will become dull over time when exposed to too much light.

Excessive heat and sudden temperature changes may also fracture certain stones. Heat can easily remove the natural water content, and these gems depend on moisture to maintain their beauty. For example, pearls can dry out, crack and change color. Opals can turn white or brown, develop tiny cracks, and may lose their tourmaline color.

Tips For Gemstones Jewelry Special Care

Many colored gemstones and jewelry are often treated to improve their color and clarity. These treatments can be negatively affected by heat, solvents, steam and ultrasonic cleaning machines.
