This is a circa 1970s mod version of an Egyptian Revival style fan necklace in solid sterling silver interspersed by black glass cube beads. This necklace is heavy. The fan of silver bars are all solid silver, not hollow tubes. When I first got this necklace it's original silver chain had broken under the weight of the necklace, so I replaced that chain with a sturdier sterling silver chain. One black bead had been lost leaving an odd remainder, so I attached the left over black bead to the clasp as a dangle. The necklace now has a nice Italian made sterling box chain base, 36 round silver 8mm beads, 14 black cube beads + the extra as a dangle, and 15 silver rods in graduated lengths. I am sure this is a designer piece, perhaps for the runway, but lacking a marking or tag I can't identify it. There are no markings except on clasp of the chain marked 925 Italy. Other metal tests strongly positive for silver content of sterling grade.
This necklace weighs 205.9 gr. - that is over 7 ounces of mostly silver content less the weight of the black beads. There is over $100 in silver value alone. the necklace chain is 19" wearable length. the original was probably more like 18" but I gave it a little more breathing room. The longest silver rod measures 3" long. The black cube beads are subtly tapered in size from about .25" up to .375".
Condition is good, with only modest wear to the round silver beads. Chain has been replaced with a better one.
You will look amazing wearing this striking necklace. Heads will turn, and you will be the only one to have one like it. I am sorely tempted to keep this one for myself so nab it before I yank it back into my own closet.
