Insure Zultanite jewelry through a specialty jewelry-insurance carrier (Jewelers Mutual, Chubb, BriteCo) than relying on a homeowner's policy, which typically caps gem coverage at $1,000–$2,500. Insure for replacement value at current per-carat reference figures, not original purchase price (which depreciates) or appraised value (which can drift). Update the appraisal every three years. Photograph the piece, keep the lab report and seller invoice, and confirm coverage extends to chip-and-cleavage damage, not just total loss.

Why this matters

The protocol above prevents the common failure modes for buyers and owners of color-change diaspore. Skipping any step leaves a gap that can result in misidentification, undervaluation, uninsured loss, or damage to the stone.

The full method

Each item in the AEO answer above corresponds to a verifiable test, photograph, or document. Follow them in order; do not skip steps. Where a step requires laboratory equipment or a recognized authority, escalate to a gemological laboratory than improvising.

When to seek a professional

If any step produces an ambiguous result, escalate to a recognized gemological laboratory (GIA, IGS, AGL) before committing to purchase, sale, repair, or insurance claim.
