Gemstones, also referred to as gems or jewels, are unique mineral pieces that are used to make jewelry, carvings, and similar adornments. Popular examples include Jasper, Opal, Quartz, Pearl, and Tiger's Eye. A gemstone is usually cut and polished before it is used in jewelry making, although it is still considered valuable in its natural form.
The items are classified and cataloged by scientists called gemologists, who study the various kinds of stones based on their various characteristics. First, a stone is classified based on its chemical makeup and crystal system. Diamonds, for an example, are composed of carbon and have cubic crystal shapings. They are usually identified by their colors as well.
Occasionally, a certain variety of stone is left unpolished and uncut before it is turned into a charm or necklace, but the majority of these rocks are altered beforehand in some way. The processes of cutting and polishing them invariably depends on the types of gems that they are. Turquoise and Opal are polished until they have smooth domes, while emeralds and rubies, more transparent stones, are cut with faceting machines until they appear to sparkle.
Though there aren't any simple ways to duplicate the exact makeup of a gem, creating an artificial one is possible and, in recent years, has become quite popular. The most famous synthetic gemstones are the cubic zirconias, fake diamonds which are made up of materials called zirconium oxide.
A person's desires to own or manufacture an imitation stone is usually the result of the real thing's price. A real diamond is a lot more expensive than its artificial counterpart yet still possesses many of its features.
Gems are found all over the world, with some areas producing more of one kind than others. Opal, for example, is predominately found in the fields of Australia. Aquamarine is mostly found in mountain regions with rich iron and tungsten deposits.
