Would have to meet several tests. 1) Hosting company knew and agreed to the value of the things they had control over. 2) Employee did it and they were negligent in hiring that individual. 3) Reasonable and customary for that type of stuff to be in that situation given pricing and the practices of others.

With respect for #3 it would be reasonable for a bank safe deposit box to contain a $100,000 ring maybe but not to contain a 10,000,000 ring.
