Archaeological-revival gold and hardstone intaglio necklace, Italy, circa 1870

Supporting 26 oval intaglios carved with themes and motifs from Classical antiquity, including carnelian, amethyst, garnet, chrysoprase, jasper, bloodstone and glass, alternating with rod fringes with floret terminals, length 14¾ inches, Italian assay mark, clasp deficient. 

One garnet is cracked and there is epoxy residue to the perimeters of several intaglios (seen only on the reverse). Otherwise, the necklace is in excellent condition. There is an Italian assay mark (star) for 1934 indicating the piece was in a jeweler's stock in Italy at the time, but the piece was made earlier. The clasp is missing, which was probably an S hook.
