Most common minerals are identified visually by taking into account color,
transparency, luster, crystal shape, cleavage, bruising, mineral habit, and
mineral associations. This knowledge is acquired by observing many examples
of how minerals may vary. This collection of mineral photos has been designed
to assist in this learning process. Emphasis is on commonly encountered,
typical mineral specimens.
