Vintage "Coro" Cutout Silver necklace

"Coro Jewelry" is most noted for it's collections from the 1930's thru the 1950's. Their great success was due to their quality of design and to their affordability of their pieces. I found this one at a cool style-design store in Minneapolis in the early 2000's. Stainless circle cut-out on chain with 2 matching medallions. 3 White enamel beads. "Coro" stamp on back. Hangs about 18" long. Pristine condition.
