Rich onyx meets luxe, gold-filled disk-links in these quietly glamorous vintage bracelets. These pieces read both elegant and a lil’ sexy, and are too dang gorgeous to be reserved only for fancy dresses. In fact, our favorite way to wear these are with jeans & a sweater (push up the sleeves, add heels, lipstick…and a wink).

From 1940s-60s.
