From Middle English crystal, cristal, criȝstall, representing a merger of Old English cristalla (from Latin crystallus) and Anglo-Norman cristall, Old French cristal (from Latin crystallum). The Latin is derived from Ancient Greek κρύσταλλος (krústallos, “clear ice”), from κρύος (krúos, “frost”), from Proto-Indo-European *krews- (“hard, hard outer surface, crust”).

“He tells me he's been shooting crystal, which I already pretty much know because he does not bother to keep his sleeves rolled down over the needle tracks.” — 1968, Joan Didion, “Slouching Towards Bethlehem”, in Slouching Towards Bethlehem:
“Come, let's away. My loue, giue me thy Lippes: Looke to my Chattels, and my Moueables: [...] Goe, cleare they Chryſtalls. Yokefellowes in Armes, let vs to France” — 1599 (date written), William Shakespeare, “The Life of Henry the Fift”, in Mr. William Shakespeares Comedies, Histories, & Tragedies […] (First Folio), London: […] Isaac Iaggard, and Ed[ward] Blount, published 1623, →OCLC, [Act II, scene iii], page 75, column 2:
