A crystal or crystalline solid is a solid material whose constituent atoms, molecules, or ions are arranged in an ordered pattern extending in all three spatial dimensions. In addition to their microscopic structure, large crystals are usually identifiable by their macroscopic geometrical shape, consisting of flat faces with specific, characteristic orientations.

Famous quotes containing the word crystal:
“In a few days I’ll have lived one score and three days in this vale of tears. On I plod—always bored, often drunk, doing no penance for my faults—rather do I become more tolerant of myself from day to day, hardening my crystal heart with blasphemous humor and shunning only toothpicks, pathos, and poverty as being the three unforgivable things in life.”
—F. Scott Fitzgerald (1896–1940)
“Wynken, Blynken, and Nod one night
Sailed off in a wooden shoe—
Sailed on a river of crystal light,
Into a sea of dew.”
—Eugene Field (1850–1895)
“But the thing that I saw in your face
No power can disinherit:
No bomb that ever burst
Shatters the crystal spirit.”
—George Orwell (1903–1950)
