Quartz Crystals - Their Identification and Meanings ...

Quartz crystals are natural modulators, transmitters, and containers of the Universal Life Force. As they are grown within the earth, they take on a unique shape and often gather inclusions of other minerals that affect their abilities to modify, store, and transmit the Life Force.

Why Do Crystals Have Different Shapes? | Reference.com

Why Do Crystals Have Different Shapes? Crystals grow in different shapes because of the internal symmetry of the crystal and the growth rate along the direction of the crystal. The arrangement of the atoms in a crystal is called a lattice.

Crystal habit - Wikipedia

39 · In mineralogy, crystal habit is the characteristic external shape of an individual crystal or crystal group. A single crystal's habit is a description of its general shape and its crystallographic forms, plus how well developed each form is. Recognizing the habit may help in identifying a mineral.

Smithsonian Education - Minerals, Crystals and Gems

Most minerals occur naturally as crystals. Every crystal has an orderly, internal pattern of atoms, with a distinctive way of locking new atoms into that pattern to repeat it again and again. The shape of the resulting crystaL-such as a cube (like salt) or a six-sided form (like a snowflake)-mirrors the internal arrangement of the atoms.

Crystals are solid material in which the atoms are arranged in regular geometrical patterns. The crystal shape is the external expression of the mineral's regular internal atomic structure. Temperature, pressure, chemical conditions and the amount of space available are some of …

Crystal Shape - Chemeketa Community College

When minerals form in environments where they can grow without interference from neighboring grains, they commonly develop into regular geometric shapes, called crystals, bounded by smooth crystal faces. The crystal form for a given mineral is governed by the mineral's internal structure, and may be distinctive enough to help identify the mineral.

Crystals of the same mineral tend to show the same general crystal shape. Quartz, for example, is almost always prismatic, rather than tabular or equidimensional. However, the exact shape of crystals of the same mineral can vary, depending on the conditions at the time of growth. Two crystals of the same mineral may differ in the relative sizes ...

In crystallography, mineral habits refer to the way crystals form within a specific mineral. In the article, "How Gems Are Classified," I mentioned that, at the molecular level, diamond looks like two pyramids attached at their bases and quartz has six sides. These are examples of mineral habits or crystal systems.
