Jewelers block coverage is not limited to only retail jewelers. Any risk that has jewels, jewelry, or precious metals in its inventory needs this coverage because standard commercial property policies significantly limit theft coverage on such property. Every market for this coverage requires detailed applications, known as proposals that become part of the policy. Security systems with maintenance agreements are required and a warranty on the policy requires that both remain in proper operating service throughout the policy’s term.
