Gem Certification Services

Certifications for your precious diamond or gem


A certified gem has been scientifically evaluated by qualified Gemologists using high-powered microscopes and other instruments to provide an unbiased assessment of gem quality.

We are able to provide certification services for your precious diamond or gem to give you peace of mind. Certification is often undertaken for insurance purposes. In some cases, certification can increase the value of a gem.

We currently offer two routes of gem certification.
