Jewelry insurance comes in many forms and varieties and only an insurance agent can provide accurate and specific advice. I am only presenting some basic guidelines here.
But, you need to know enough about jewelry insurance to ask your agent the right questions and to be aware of how the process works. And furthermore, you need to ask your insurance agent the questions before you insure an item, not when you need to file a claim. The most important thing you need to do is to read the fine print in your insurance contract to be sure it provides the coverage you expect.
