History and Etymology for crystal

Noun

Middle English cristal "transparent quartz, object made from it," borrowed from Anglo-French, borrowed from Latin crystallum, crystallus, crustallum "clear ice, rock crystal," borrowed from Greek krýstallos, probably borrowed from a pre-Greek substratum; replacing Old English cristalla, cristal, cristallum, borrowed from Latin crystallum

Note: Greek krýstallos was traditionally linked etymologically with krýos "icy cold, frost" and Latin crusta "hard surface layer," though the morphological details were not explicable (and crusta does not refer to ice or cold). More likely, as asserted by Robert Beekes (Etymological Dictionary of Greek [Leiden: Brill, 2010], p. 787), krýstallos, as evidenced by the suffix -allos (from *aly- according to Beekes) and the variant króstallos, is of pre-Greek origin. Cf. notes at cryo-, crust.
