Loose Stone: “Insuring a Loose Diamond Before Setting”

I bought a loose diamond for $15,000 to have a custom ring made. I kept it in a drawer. It was stolen. My insurance denied it because “Jewelry” implies a finished piece, and “Unset Gems” are often excluded or require specific scheduling.

Key Takeaways

  • Unset Gems Exclusion: Many homeowners policies exclude loose stones because they are high-risk (easy to lose, swallow, or fence).
  • Scheduling as “Loose Stone”: You can insure a loose diamond, but you must describe it explicitly as “Unmounted Diamond” on the schedule.
  • Course of Construction: When you give the stone to a jeweler to set, ensure the insurance covers it while at the jeweler. (See Article 4).
  • Value Change: Once set, the value increases (Stone + Setting + Labor). You must update the appraisal and policy immediately upon completion.

The “Why” (The Trap)

The trap is “Classification.”

Is a loose diamond “Jewelry”? Or is it “Bullion/Commodity”?
Insurers dislike loose stones because they are fungible.
If you insure a “Diamond Ring” but you only possess a “Diamond,” and it’s stolen, the description doesn’t match the asset. Claim denied.

The Investigation (My Analysis of Loose Gem Coverage)

I checked who covers the rock before the ring.

Jewelers Mutual

  • The Verdict: Yes, they cover loose stones.
  • The Process: You list it as “Loose Diamond.” When it gets set, you log in and update the item to “Diamond Ring” and increase the value.

Homeowners

  • The Verdict: Risky. Unscheduled loose gems are often capped at $500 or excluded entirely.

The “Transit” Gap

  • The Risk: Carrying the loose stone to the jeweler. This is when it’s most vulnerable. Ensure your policy covers “In Transit.”

Step-by-Step Action Plan

  1. Insure at Purchase: Insure the stone the day you buy it. Use the invoice as proof.
  2. Specify “Loose”: Ensure the policy says “Loose Diamond.”
  3. Update at Setting: The day you pick up the finished ring, send the new appraisal (Stone + Setting) to the insurer.
  4. Check Bailee Coverage: Confirm the jeweler has insurance before leaving the stone with them.
