ColoredGemstones

There are many different types of colored gemstones, some of which require specific care and cleaning procedures. It would be impossible to enumerate all of them. There are some general care and cleaning rules, which apply to all colored gemstone jewelry.
Many natural gemstones are treated or enhanced from the time they are extracted from the earth by one or more traditionally excepted jewelry industry practices. These treatments and enhancements can affect how you should clean and care for your colored gemstone jewelry. Consult a jeweler for information on caring for treated or enhanced gemstones.
After wearing, wipe your precious gemstone jewelry thoroughly with a clean, soft, slightly damp cloth. This will enhance the gemstone’s luster and ensure that your jewelry is clean before storing.
Store gemstone pieces individually in soft pouches. You can obtain these from a jeweler. Do not expose your precious gemstone pieces to salt water or harsh chemicals, such as chlorine or detergents. These chemicals may slowly erode the finish and polished gemstones.
Hair spray, perfume and perspiration may cause jewelry to become dull. Apply all cosmetics, perfumes and colognes before putting on colored gemstones jewelry. Make sure to wipe your gemstones after wear to remove any chemicals, oils, or perspiration.
Do not subject gemstone jewelry to sudden temperature changes.
If you have an active lifestyle, take extra precautions with some types of gemstone jewelry. Emeralds, for example, are brittle and should not be worn when doing household chores or any other activity where the stone could be hit or damaged.
Be extra careful with ultrasonic cleaners. Some gemstones are fragile an can be damaged by ultrasonic cleaners. Consult your jeweler for the best cleaning procedure for your particular gemstone jewelry. A jeweler is also the best source for any information on colored gemstones.
