Amethyst is the birthstone for February and has a purplish-gray color. Amethyst is used for its supposed "healing powers". Some people believe that when they wear Amethyst is will and rid them of negativity. Amethyst can be found all around the world. However, the main places are Brazil, Uruguay and Madagascar. Amethyst is mined by using subsurface mining.


The definition of a mineral is made up of five parts. The first two parts of a mineral is that a mineral is naturally occurring and that it is a solid substance. When a mineral is formed it is not man-made however, it is made from natural process. A mineral is not a liquid or a gas. Another part of the definition is that a mineral is inorganic, which means that it is made from non-living materials, and that a mineral has a definite chemical composition. The last important part of the mineral definition is that a mineral has a crystalline structure.

Identifying A Mineral

Identifying a mineral takes a series of eight steps to complete. The eight steps include color, luster, streak, cleavage/fracture, hardness, density,and by diaphaneity. Color is a property possessed by an object. The color of my mineral, Amethyst, is purple. Luster is the way a mineral reflects light. The luster of my mineral is metallic because it shines like metal. The streak means the color of a mineral in powdered form. Amethyst's streak is the color white. Cleavage or fracture is the way the mineral breaks. Amethyst has a fracture brake because there isn't a clean cut. Hardness is a minerals resistance to being scratched. The hardness level of my mineral is 7 because it is above the average and can scratch glass. Density is the measure of how much matter is in a given amount of space. The density of Amethyst is 2.65g/cm3. Diaphaneity is when a mineral is perfectly clear, allows light to pass through, or if it is opaque. Amethyst is mainly opaque, however, some areas of the mineral are known to be transparent.

Special Properties

There are 7 special properties a mineral can have. They include fluorescence, magnetism, chemical reaction, taste, optical properties, smell, and radioactivity. Fluorescence is when a minerals glows on its owns when under an ultra violet light. Amethyst does not have the special property of fluorescence. Magnetism is when the mineral is magnetic. Amethyst is not magnetic. Chemical Reaction is when the mineral will have a chemical reaction to certain experiments. Amethyst does not have chemical reactions. Taste is what the mineral tastes like when it hits your taste buds. Amethyst does not have a specific taste. Optical properties is when a mineral can create a double image when placed over an image. Amethyst can sometimes create a double image. In some areas of the mineral there is a clear enough color to create a double image. Smell is how to detect something while using your nose. My mineral Amethyst lacks a specific smell. Lastly, radioactivity is the emission of radiation. Amethyst is not radioactive.
