When there is just a big hunk of a mineral, it is called a massive mineral. If there is a definite shape with easy to see flat sides, it is called a mineral crystal. Most of the earth's crystals were formed millions of years ago. Crystals form when the liquid rock from inside the earth cool and harden.

The Seven Crystal Systems Information   crystalage

The Seven Crystal Systems Information crystalage

The seven crystal systems are a method of classifying crystals according to their atomic lattice or structure. The atomic lattice is a three dimensional network of atoms that are arranged in a symmetrical pattern. The shape of the lattice determines not only which crystal system the stone belongs to, but all of its physical properties and appearance.

No crystal system even approaches a sphere's degree of symmetry, but the isometric system is often quickly recognizable because some of the forms and combinations of forms somewhat approach sphericity (or, at least, roundness), especially when the faces begin to be curved, due to the high degree of symmetry in the isometric system.

All forms in the Isometric Crystal System are closed forms. That is, the faces of the form completely enclose space. Hexoctahedron The hexoctahedron [6 x 8] is the general form for the isometric hexoctahedral class. It has 48 faces, each of which is a scalene triangle and intercepts all three axes.

The Isometric crystal system characterizes itself by its three equivalent crystallographic axes perpendicular to each other. This means that undistorted crystals do not look elongated or flattened. They look like objects that could fit within a sphere. The Isometric System comprises six Crystal Classes.

In the isometric system a general form would have to be something like {123}. Open Forms and Closed Forms. A closed form is a set of crystal faces that completely enclose space. Thus, in crystal classes that contain closed forms, a crystal can be made up of a single form.

Cubic crystal system   </h3>OVERVIEWVOIDS IN THE UNIT CELLMULTI ELEMENT COMPOUNDSWEAIREPHELAN STRUCTUREIn crystallography, the cubic crystal system is a crystal system where the unit cell is in the shape of a cube. This is one of the most common and simplest shapes found in crystals and minerals. There are three main varieties of these crystals Primitive cubic Body centered cubic Face centered cubic Each is subdivided into other variants listed below. Note that although the unit cell in these crystals is conventionally taken to be a cube, the primitive unit cell often is not.
