For the subject on the underside compare the "Greek Style" Greco-Persian chalcedony scaraboid from Megalopolis, now in Berlin, pl. 854, in Boardman, Greek Gems and Finger Rings. For lion gems see Boardman, op. cit., p. 205. Lion gems are usually cut from carnelian, with their undersides bearing purely Greek devices, while some are lacking intaglios and were worn as ornamental rings.
