What to Expect

Appraisals While You Wait

Examination and necessary tests are performed while you watch. Your appraisal is a bound report and includes a full description, a digital image and a plot of all diamonds over half a carat.

You will walk away with your jewelry, and barring anything extraordinary, you will receive the bound report at the end of your appointment.

Jewelry Appraisal Information

Your jewelry appraisal is professionally prepared to the highest standards.
