quartz

Quartz is a relatively well-known gemstone, with many types and quantities in circulation. It is broadly classified into two types: transparent to translucent single crystal and translucent to opaque polycrystal. Single crystal stones include amethyst, citrine, and rose quartz, while polycrystalline stones include chalcedony, agate, and jasper. Many contain other minerals and liquids as inclusions.
