Jewelers Block Insurance

Jewelers block insurance is a package inland marine form built specifically for the jewelry trade. "Block" refers to covering a block of interests under one policy: the jeweler's own stock of gems, precious metals, and finished pieces; customers' property and memorandum/consignment goods held as a bailee; and merchandise in transit by mail, courier, or salesperson. It is broader and more tailored than a generic property or bailee's customer form because it contemplates the high theft exposure, mobility, and fluctuating values unique to jewelers.

For a small jeweler this is often the most important coverage they buy, because stock values can dwarf building values and standard commercial property forms sharply limit or exclude jewelry, cash equivalents, and property in transit. Jewelers block responds to theft, robbery, burglary, fire, and most accidental damage, and it follows the merchandise off premises — to trade shows, appraisers, repairers, and traveling salespeople. Underwriters scrutinize protective safeguards closely, so premiums and eligibility hinge on alarm systems, safes and vaults, and locking-up procedures; a protective safeguards endorsement may make certain security measures a condition of coverage.

Key nuances for buyers involve sublimits and valuation. Policies impose separate sublimits for goods out on memorandum, unattended vehicles, window and showcase displays, and out-of-safe amounts after hours — a claim can be denied or slashed if merchandise was left outside the safe against policy terms. Stock is usually valued at the jeweler's cost, not retail, so business-interruption or lost-markup exposure may need separate business income coverage. Buyers should also verify whether window-smash "grab-and-run" theft and off-premises salesperson exposure carry adequate limits for their actual selling patterns.
