| HOW TO TAKE CARE OF YOUR JEWELRY Gems and precious metals are gifts of nature, which need special care. Even though a gem may be millions of years old, once mined and worn, it is exposed to conditions and chemicals that can damage it. The harder the gem, the less vulnerable it is to potential damage. A diamond, for example, is the hardest gem known to man, and that's one reason why "it is forever." Hardness is based on a gem-trade standard called the Mohs Scale, developed in the early 19th century. The scale is structured so that material rated at each higher number can scratch substances with lower numbers. Diamonds are rated the highest, at 10; rubies and sapphires are Mohs 9; emeralds and topaz, 8; and garnets, tourmaline's and quartz, 7. Anything softer than a 7 can be scratched, including opal, turquoise, lapis lazuli, coral, pearl. Gold, silver, and platinum are only Mohs 2-1/2 to 4, which means that they require special care when wearing, storing, or cleaning. Gold and Platinum - The Metals Twenty-four karat gold is 100% gold and is considered too soft for jewelry and is alloyed with other metals to increase its durability and workability. 18 karat gold is 18 parts of gold and 6 parts other metal (75% gold) and 14 karat gold is 14 parts of gold and 10 parts of other metal (58% gold). Platinum is at least 90% platinum often alloyed with iridium or ruthenium for hardness and is more durable than gold. Gold and Platinum General Care Always separate your jewelry when putting it away. This protects against scratching. A jeweler's polishing cloth can keep your jewelry looking lustrous and shiny. Remove your jewelry when doing rough work or sports. Gold and even platinum may become scratched from contact with other objects. Rings may be knocked out of round with hard use and prongs could crack with a hard blow. Remove all jewelry before bathing, doing dishes or other household chores. Soap and detergents can cause a film to form on your jewelry, making it appear dull and dingy. Some chemicals such as chlorine bleach cause pitting or discoloration of the metal. Check clasps to ensure that they work freely and have not become worn. It is safer to replace a worn clasp than to risk the loss of the entire piece. Be careful when wearing and putting away serpentine or herringbone chains. It is best to hang them to prevent kinking and bending. Cleaning Your Gold and Platinum Jewelry Never clean pearls with chemicals, abrasives or most jewelry cleaners. When cleaning gold and platinum jewelry we recommend a cleaner that is safe for gemstones too, such as Jeweler's Secret(TM). Its gentle action should restore the luster to gold and platinum and will not harm the gemstones. Luster may also be improved by using a polishing cloth. |
