Why should I have my jewelry evaluated by a gemologist?
Unlike a jeweler, a gemologist can identify and determine if the gemstones within your jewelry are natural, synthetic, and most importantly if your gemstone has been treated in any way. This information is very important to know because depending upon the stone and any treatments it has undergone, your gemstone(s) can be damaged if stored incorrectly, and if your jewelry requires repair. An example of this is pearls. Pearls should never be stored in plastic because the gases emitted by plastic will damage the surface of a pearl. Additionally, pearls require some humidity in the surrounding air to prevent them surface damage. Given this information, safe deposit boxes are never ideal for pearls simply because the environment is controlled to minimize humidity in the vaults. Various other gemstones have special requirements as well. These include, but are not limited to treated ruby, natural opal, and natural emerald.
