I have my stuff insured through USAA and they are wonderful. We live in NYC, so we don't have a house or a car, but somehow they agreed to let us get a jewelry policy through them (started it with my engagement ring but have gradually been adding other items to the policy, ie watch, purse, etc). If you have either a house or car policy, though, I think you can usually add jewelry onto it pretty easily with most insurance companies. Also, I think some ladies mentioned an insurance company called CHUBB, that is specifically for jewelry, so separate from a homeowner's policy (I don't have any experience with them, so I can't comment).
