It also has a distinct basal cleavage that breaks to form vitreous fracture surfaces perpendicular to the long axis of the crystal. This cleavage makes topaz a more fragile gemstone than its hardness of 8 would imply. Topaz is very hard, but it has a low tenacity, which means it chips and cleaves easily.

2.3 Mineral Groups Most minerals are made up of a cation (a positively charged ion) or several cations and an anion (a negatively charged ion (e.g., S 2-)) or an anion complex (e.g., SO 4 2-). For example, in the mineral hematite (Fe 2 O 3), the cation is Fe 3 + (iron) and the anion is O 2- (oxygen). We group minerals into classes on the basis of their predominant anion or anion group.

Cleavage / fracture. Cleavage and fracture describe different ways in which a mineral can break. Definitions. Cleavage - The tendency of a mineral to break along flat planar surfaces as determined by the structure of its crystal lattice. These two-dimensional surfaces are known as cleavage planes and are caused by the alignment of weaker bonds between atoms in the crystal lattice.

Cleavage: In mineral terms, cleavage describes how a crystal breaks when subject to stress on a particular plane. If part of a crystal breaks due to stress and the broken piece retains a smooth plane or crystal shape, the mineral has cleavage. A mineral that never produces any crystallized fragments when broken off has no cleavage.

clue in identifying minerals . The color of the powder left by a mineral when it is rubbed against a hard, rough surface is called streak. Streak color is use to identify minerals that have a characteristic streak color and are fairly soft. Even though the mineral color may vary, its streak is always the same. REMEMBER: Streak color is often different from the color of the mineral itself.

Pyrite was once used as a source of sulfur, but is now only a minor ore for both sulfur and iron. Pyrite from some localities is auriferous, and therefore is used as an ore of gold in gold-bearing localities.Pyrite was polished by the Native Americans in the early times and used as mirrors. Today, it is used as an ornamental stone, as well as a very popular stone for amateur collectors.
