Taking care of gemstones
Steam cleaning is quite effective but can result in thermal shock because of the often-quick temperature change. It can result in cracking because parts of the stone are forced to expand at different times. Most gemstones can be immersed in a solution of mild detergent and warm water.
Likewise with pearls; although soaking can result in discoloration, so this should always be avoided. After soaking for a few minutes, gently clean the stone with a soft brush. Pearls should be dried after cleaning, using a soft towel, and air-blown dry. Extra care should be taken to remove dirt from the bottom of the setting, a common place for build-up to occur.
Gems are silicates which can be very stable, hard minerals. Like gemstones, one of the characteristics of a precious metal is its rarity. A few gems are oxides and only one gem, diamond, is composed of a single element, carbon. Often, new names will be created for ordinary sounding minerals which sound prettier or more valuable, such as Moldavite for the green variety of tektites.
It could not be "precious" if it were common! This means that the metal must be malleable, that it can be bent, hammered, or otherwise shaped. Two other characteristics are also important. There are also many gemstones that are not true minerals, but which are gemstone varieties of recognized minerals.
