jasper (n.) Look up jasper at Dictionary.com
precious stone, c. 1300, from Anglo-French jaspre, Old French jaspre, with excrescent -r-, a variant of jaspe (12c.), from Latin iaspidem (nominative iaspis), from Greek iaspis "jasper," via an Oriental language (compare Hebrew yashpeh, Akkadian yashupu). The modern use of the word is more restricted than in ancient times. Hence, from French, jaspé (1851 in English) "mottled or variegated like jasper."
