Treatment disclosure is the communication of relevant information about treatments applied to a diamond, gemstone, pearl, or other jewelry material. It helps buyers understand whether appearance, durability, care requirements, or value may be affected by an enhancement or processing method.
What Is Treatment Disclosure?
A treatment disclosure identifies a known treatment when that information is material to the buyer. Examples can include heat treatment, fracture filling, dyeing, irradiation, diffusion, bleaching, coating, laser drilling, or other enhancement methods depending on the gem material.
What Information Does Treatment Disclosure Include?
Useful disclosure states the type of treatment when known and may explain whether it is permanent, whether it requires special care, and whether it can affect value or future servicing. The exact wording and legal requirements vary by market and jurisdiction.
Who Issues or Uses Treatment Disclosure?
Sellers, jewelers, laboratories, manufacturers, and appraisers may communicate treatment information. A gemological report may record detected treatments, while a retailer may also need to disclose relevant treatment information at the point of sale.
How to Verify and Interpret Treatment Disclosure
Review laboratory documentation and seller disclosures together, ask whether the treatment is stable and whether it changes cleaning or repair recommendations, and keep the documentation with the jewelry. Some treatments can be difficult to identify without laboratory testing, so absence of visible evidence should not be treated as proof that a stone is untreated.
