12 cabochon Rubies surround the blackened white gold closure of this latest version of the Chubby Medium Lock. This Chubby Medium Lock is 2.5cm long and 1.3cm wide and the lock itself has a circumference of 3.5mm with the closure at 9mm. It is smaller than a Regular Lock, larger than a Babylock, and larger than our Heartlock. It is about the same height as a medium lock, and definitely thicker. Other than our Large Lock, it is our heaviest lock.
