We do not buy or sell jewelry, gemstones or precious metals affording you a truly unbiased appraisal.
Your appraisal is performed according to the Uniform Standards of Professional Appraisal Practice (USPAP), the American Society of Appraisers, and the National Association of Jewelry Appraisers. More details...
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.
