IRV introduces mandatory diamond screening

The Institute of Registered Valuers (IRV) has published renewed regulations that stipulate all diamonds must be screened when being valued to conclude whether they are natural or synthetic.

The appraisal body, operated by the National Association of Jewellers’ (NAJ), said the change will strengthen professional standards across the valuation industry by clarifying and standardising best practice.

The IRV said that the updated measures align with technological development in the diamond market that have increased the prevalence of synthetic (laboratory-grown) diamonds and made them impossible to differentiate from natural stones with traditional methods.

It added that without sufficient screening, valuers face a higher risk of misidentification, which can lead to incorrect valuations, client misunderstandings and greater professional liability.

For IRV members, the association said the reforms boost professional credibility and due diligence, lower chances of dispute and correspond with international best practice.

It added that it is also working with insurers to make sure the refreshed standards are recognised, further strengthening the IRV members’ value and credibility in the marketplace and clearly separating from non-compliant valuers.

The IRV is providing its members with refreshed technical guidance and continued professional development opportunities to support them through the transition.

IRV chair, Sammantha Maclachlan, said: “The diamond market has changed fundamentally, and our standards must reflect that reality. By introducing mandatory screening, the Institute of Registered Valuers is ensuring that our members continue to deliver accurate, transparent, and defensible valuations.

“This is about protecting both the valuer and the client, and about leading the profession forward. By taking this step, the IRV is actively shaping the future of valuation standards and not simply responding to it.”
