Insurers pricing cover for lab-grown diamond jewellery are lowering premiums to track falling replacement costs, a shift natural diamond insurance hasn't seen in the same way.

  • Insurance premiums are generally priced against current replacement value, so as lab-grown prices keep falling, the cost to insure a given piece falls with it.
  • This is the mirror image of the ageing appraisal problem we've flagged on the natural side, where old appraisals now understate replacement cost rather than overstate it.
  • Owners of lab-grown pieces insured a few years ago may be paying for cover well above what the piece would now cost to replace.

If a lab-grown piece was insured more than a year or two ago, it's worth asking for a current replacement-value reappraisal to check the premium still matches. Contact us for an updated valuation.
