Jewelry Appraisal Appointments,
Fees & Tacoma Location

Appraisals are done by appointment only. If necessary, we can schedule appointments for evenings or Saturdays.

Jewelry appraisal fees are based on either a per item charge or on an hourly basis.  The minimum fee for a single item is $100.00. Appraisals are never based on a percent of the appraised value — that is unethical.
