jewelry (n.)

late 14c., juelrye "precious ornaments, jewel work," from Old French juelerye, from jouel (see jewel). In modern use it probably is a new formation and can be analyzed as jewel + -ery or jeweler + -y (1). Also jewellery. "The longer is the commercial & popular form, the shorter the rhetorical & poetic" [Fowler].
