Final answer:
Standard homeowners insurance usually has sub-limits for jewelry that are below the value of Dianne's rare jewelry collection; she would need additional insurance such as a valuable items policy or a personal articles floater.
The statement is false.
Step-by-step explanation:
The statement that Dianne's standard homeowners policy should provide adequate insurance protection for her rare jewelry collection valued at $250,000 is typically false.
Standard homeowners insurance policies usually have limits on coverage for personal items, especially for valuables such as jewelry. Most policies set a sub-limit for theft of jewelry, which is much lower than $250,000, often around $1,500 to $2,500. To insure her collection adequately, Dianne would likely need to purchase a separate valuable items policy or a personal articles floater that can offer higher limits and cover items on an agreed value basis.
