Onyx embedded in .925 silver bracelet!

A beautiful black onyx embedded in 925! The onyx itself is about 15mm x 12mm. It is stamped with a maker, but I'm not entirely sure - can't make it out really. The bracelet hooks and unhooks from the onyx piece. Will fit a smaller wrist - maybe 6.5" Please inspect and enlarge the pictures to assess the condition of the item for yourself.
