Crystal FAQs:


Q: Are crystals usually identifiable by their geometrical shape?

A: Yes, and consisting of flat faces with specific, characteristic orientations.

Q: Is a crystal oriented in a specific way relative to the underlying atomic arrangement of the crystal: they are planes of relatively low Miller index?

A: Yes.

Q: Is a crystal scientifically defined by its microscopic atomic arrangement?

A: Yes, and not its macroscopic shape—but the characteristic macroscopic shape is often present and easy to see.

Q: Is a crystal constrained by the requirement that the unit cells stack perfectly with no gaps?

A: Yes.

Q: Are crystals often used in pseudoscientific practices such as crystal therapy?

A: Yes, and and, along with gemstones, are sometimes associated with spellwork in Wiccan beliefs and related religious movements.

Q: Is a crystal one grain in a polycrystalline solid?

A: Yes.

Q: Is a crystal supposed to consist of smaller crystalline units that are somewhat misaligned with respect to each other?

A: Yes.

Q: Are crystals occasionally found?

A: Yes.

Q: Is a crystal a solid where the atoms form a periodic arrangement?

A: Yes.

Q: Are crystals commonly recognized by their shape?

A: Yes, and consisting of flat faces with sharp angles.

Q: Are crystals those with obvious?

A: Yes, and well-formed flat faces.
