The name Agate comes from the Greek words for "hard stone"white." AChat or agates means "hard-colored stone" in Sanskrit. Agates vary greatly in color from dark brown to light purple. Agate is a soft-colored rock that consists of quartz and chalcedony as its main elements, consisting of many colors ranging from violet to dark blue.
The formation of agate is the result of intense heat, which causes a process called metamorphism. Agate occurs in limestone, calcite, marble, granite and other rocks found in the world. It is formed under high temperatures and pressures. The temperature in which the rock is formed is often below the melting point of the rock; therefore the material cools to form the crystal structure. Agate can also be formed in other rocks, but its properties make it ideal for forming crystals that look like crystals of quartz or Jasper.
There are several different kinds of agates, all of which are commonly used for making jewelry and art work. Some of the more common types of agate are Caspian, Black, Blue, Red, and Orange. Each type of agate has its own unique coloring and texture, so they are very hard to mistake for the common ones. Achat is used for making jewelry, such as necklaces, rings, and bracelets. It is also a stone that is usually found in ancient Egyptian temples. It is also used in modern jewelry designs and is considered a semi-precious stone. Achat is also used in making glass items.
