Terminology

 

There is no generally accepted definition for the term gem or gemstone, but they all have something special, something beautiful about them. Most gemstones are minerals (e.g., diamond), mineral aggregates (such as lapis lazuli) or rocks (such as onyxmarble). Some are organic formations (e.g., amber), and other gem materials are of synthetic origin (e.g., YAG).
