What We Do

Unbiased Valuations of Diamonds, Gemstones, Watches, Pearls and Jewelry

We do not buy or sell jewelry, gemstones or precious metals affording you a truly unbiased appraisal. Your jewelry 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.

 

How We Work

Jewelry appraisals are by appointment in a
secure environment

If the intended use of your report is for insurance purposes the cost is $135 for the first item and $85 for each additional item. This assumes there is nothing extraordinary about your item(s). Most items fall within these pricing parameters. However, if there is any additional cost, we will inform you at the beginning of the appointment.

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.
