Product Details

Each mineral has characteristics which generally can be classified according to physical properties. These may include such well-known properties as color, streak, luster, cleavage, fracture, hardness, specific gravity and others.

Not all minerals will demonstrate each of the above properties. A relatively small group of minerals has one or more characteristics which may be peculiar only to that one mineral or a small group of minerals. These characteristics may go beyond the scope of those generally thought of as physical nature. Some of these characteristics are demonstrated in this group of minerals.
