The intrinsic significance of this ancient symbol of medicine makes it a distinctive pendant that will become an heirloom the moment it is received. The pendant is 3.9 mm of solid 14K gold measured from the top of the bail (small bail) to bottom of the Staff of Esculapius. It is available with four different bails to accomodate different chain sizes and personal preferences. Each piece is initialed and numbered for authenticity. The pendant comes with a Greek natural leather cord for those who want an organic look.
