"Crystal is a solid in which the constituent atoms, molecules and ions are packed in a regularly ordered, repeating pattern extending in all three spatial dimensions. While the term "crystal" has a precise meaning scientifically, in common usage "crystal" refers to solid objects that exhibit well-defined and often pleasing geometric shapes. A gemstone or gem (also called a precious or semi-precious stone) is a piece of attractive mineral, which is used to make jewellery or other adornments when cut and polished." The more you know~
