Introduction to collecting rocks and minerals

Why do people collect rocks and minerals? There are as many reasons to collect them as there are types of collectors: for their beauty or rarity, for their monetary value, for lapidary or jewelry-making uses, metaphysical purposes, for scientific study, and for fun.

Defining rocks and minerals

What are rocks and minerals, and what is the difference between the two? A mineral, by definition, is any naturally occurring inorganic substance generally characterized by a definitive crystal structure that is classified according to the way the atoms of the mineral are arranged.
