Questions to ask your insurance agent

  1. Will my claim – and the replacement value – be more readily acceptable if the appraisal has been done by an AGS jeweler, Certified Gemologist, Certified Gemologist Appraiser or Advance Personal Property Appraiser?
  2. What is the difference between scheduled and unscheduled coverage?
  3. Is there a deductible? If so, how much? Do I have the option to increase the deductible and thus lower the premium?
  4. Is my policy all-risk (partial loss, damage, theft, etc)?
  5. Am I still covered if there is negligence or carelessness involved?
  6. Is the item covered if lost, stolen or damaged while in the possession of someone else?
  7. If there is a loss, do I have a choice of full cash-out or will I have to accept less?
  8. Can I go to whomever I wish for the replacement?
  9. What is the premium rate per thousand for full coverage? Partial? What do I sacrifice for the limitations?
  10. Am I limited to the appraisal replacement cost should there be a sizeable increase in value?
  11. What if the insured item is irreplaceable, like an antique?
  12. Are there any security precautions required? If not, would there be a premium savings if special precautions were taken, e.g., the items were kept in a home safe or in a safety deposit box when not being worn?
  13. Are there different kinds of jewelry insurance available?
  14. What is the pair and set clause? Will the insurance cover an additional amount for matching a missing item in a set if it has not been computed and stated?
  15. Will you show me the actual language in the policy that addresses each concern I’ve expressed?
  16. Will the occurrence of an insured loss effect my continuing coverage?
