Insurance question

[divmat]

I'm sure this question has come up before, but can someone please give me the names of a few good jewelry insurers based out of the USA. And please, lets not start the whole gun thing again. I have a CHL permit and a safe full of pistols and rifles.
Not the insurance I am looking for.

Just need the names of a some of the larger or more reputable insurers. I have State Farm and they will insure for me on a rider policy of course, but for my car collection I use Haggerty Insurance and their stated value policy is less than half of what State Farm would charge. I'm just curious if jewelry insurance falls along these same lines?

Thanks!
Steve
