This black Simone Rocha crystal-embellished comb is made from silver-tone brass and features black crystal embellishments. The humble hair comb is an accessory that has been keeping hair in place since the Stone Age. In fact, the most valuable comb in the world was found in the tomb of a Scythian leader near the Black Sea. Dating from the fifth century B.C., the comb is made of ten ounces of pure gold. We love a fun fact here at Browns.
