A gemstone is a piece of mineral crystal which, in cut and polished form, is used to make jewelry or other adornments. However, certain rocks, such as lapis lazuli, or organic materials that are not minerals, such as amber, coral and pearl, are also used for jewelry and are therefore often considered to be gemstones as well.
Each gemstone is unique with a special color, birthplace and story. Gemstones come in every color of the rainbow and are gathered from all corners of the world, with each colored gemstone possessing a unique creation of beautiful color.
Stones which are opaque or semi-opaque are commonly cut as cabochons. These gems are designed to show the stone's color or surface properties. Gems which are transparent are normally faceted, a method which shows the optical properties of the stone's interior to its best advantage by maximizing reflected light which is perceived by the viewer as sparkle.
