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:
“I’m headed for a land that’s far away
Beside the crystal fountains.
So come with me, we’ll go and see
The Big Rock Candy Mountains.”

And we will some new pleasures prove
Of golden sands, and crystal brooks,
With silken lines, and silver hooks.”

“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)
