Often retained as an independent appraiser and consultant, my services have been utilized by government agencies, attorneys, accountants, individuals as well as insurance companies. I have been certified as an expert witness in the Circuit and Family Courts in the State of Hawaii Judicial System.

I handle small and large estates and have assisted in the valuation and discreet liquidation of the items when needed. Unlike most so called "estate appraisers" who are just looking to buy your items, I work as a consultant looking out for your interest and the highest possible gain.

A Graduate Gemologist since 1976, Karl Nakamura is a Certified Senior Member of the National Association of Jewelry Appraisers (CSM). I am familiar with the principles of the Uniform Standards of the Professional Appraisal Practice (USPAP) and the requirements of the various types of appraisals, i.e. estate, tax, insurance, etc. 

It is important to find an appraiser who knows these standards since certain types of appraisals require strict adherence to guidelines set forth in USPAP as well as IRS requirements. Because it is not a legal requirement, many appraisers are not familiar with these standards.

While many establishments require you to leave your valuables with them (and may need to send them away for an appraisal) my state-of-the-art, in-house laboratory allows me to offer you fast, accurate appraisals, often performed while you wait.

The difference between my appraisal service and others is that I am provide the most detailed appraisals on the island in full compliance with the National Association of Jewelers Appraisers (NAJA) guidelines. Which is your assurance of proper insurance coverage and a means to identify your items positively should the need arise. As strong proponents ethical business practices, I take extra measures to assure you of the best possible service.

Karl keeps abreast of the latest developments and trends of the business by regularly attending conferences and seminars pertaining to the field of jewelry, appraisals, and gemology.
