MAGNETITE (Iron Oxide) - Amethyst Galleries: Magnetite

Magnetite is the primary oxide of iron found in meteorites (and thus presumably in asteroids). Thermite is a mixture of powdered magnetite and powdered aluminum. When ignited, the aluminum fuel burns using the magnetite as an oxidizer, resulting in much heat, aluminum oxide (corundum), and molten iron.

The Seven Crystal Systems Information - crystalage.com

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.
