Insurance Question

[timeseek]

I was talking to a friend of mine, the comment was interesting. Why have watches and/or jewelry on your homeowner's policy? Why not have a separate policy, aside from the homeowner's, this way, if a claim has to be made, it does not place the house at risk, or policy at risk, for future surcharges or cancellations.

It was a good question, and got me thinking. Do policies like that exist, specifically for watches and jewelry, that protect against loss due to theft, fire, flood, or other ways?
