You may want to consider purchasing a Personal Articles Policy. This is a separate policy, specifically for items such as valuable jewelry, antiques, fine art, collectibles, etc., that may provide broader coverage than a homeowners or renters policy.

The Personal Articles Policy may be used to insure just a few items, or it may be used to insure an entire collection.
