This necklace looks like it could be 4000 years old, brought forth from some Mesopotamian ruin. But it wasn't - it was crafted in the 1940s by the Modernist artist/jeweler/sculptor Harry Bertoia. I don't know anything about American Modernist Jewelry, but this piece makes me want to learn. My heart is glued to my ribs right now.
