What is mysterious disappearance and why does it matter for jewelry insurance?

Mysterious disappearance means an item is lost and you do not know exactly how or where. A ring that slips off at the beach, earrings lost during travel, or a watch that disappears — standard homeowners policies explicitly exclude mysterious disappearance. A standalone jewelry policy or scheduled articles floater covers it as a standard peril. For high-value pieces, this distinction can be the difference between a covered claim and nothing.
