great preloved vintage condition, this tiger's eye is set in 4 prongs and features a scrolled detail that appears to have some enameling. awesome piece of jewelry. the chain is a bronzish tone and has some discoloration please see pics no markings on this. this could easily be put on a different chain. chain length is 24in, pendant does not slide, chain would need to be removed from bail. see pics for measurements and details and condition as they are part of item listing and description. i am not a gem expert, i simply describe to best of my ability. sales are final. cotton filled box included with purchase. other items are display only.
