Yes, that deep black stone inlay on the face of this eighteen-karat yellow-gold-framed padlock pendant is onyx, and yes, the pendant actually unlocks. Just turn the white-diamond-studded dial in front until the black diamond lines up with the edge to pop up the top loop and hook on each end of the delicate gold anchor chain—which, at sixteen inches, falls to rest right against the collarbone. Pendant: black onyx inlay, white diamonds, black diamond; Chain: 18k yellow gold Chain length: 16″ Made in USA.
