According to our insurance policy, all cases must be kept locked during business hours. This is not being kept in. If we are robbed and the cases are discovered to have not been locked, our insurance is invalid. Beyond that, it’s simply good security procedure.
ALWAYS LOCK JEWELRY CASES WHEN YOU ARE NOT REMOVING OR REPLACING THINGS INSIDE THEM. THIS INCLUDES TIMES DURING A SALE WHEN FOR ANY REASON YOU HAVE TO WALK AWAY FROM THE CASE, FOR HOWEVER SHORT A TIME.
Because of the value of the diamonds in the center case, I would require that the biggest diamonds be set up more forward of the case. This keeps any criminals from being able to reach over and grab one out of the open back of the case. Because of this possibility, all cases need to be kept locked at all times, even when showing jewelry. Take out item(s) and close and lock the case.
