With a well earned reputation of professionalism and expertise, we are recognized as Seattle’s jewelry authority, providing appraisal, gemological services and guidance to the public, the jewelry trade, insurance companies, legal firms, financial institutions, and government agencies. 

As independent appraisers, we are not affiliated with any retail or online stores, and neither buy nor sell jewelry.

We believe that every piece of jewelry has a story to tell, from how it’s made to the nature of the gemstones, and we do our best to discover and relate that story to our clients.

Appraisals are by appointment and conducted in your presence in a private and secure setting.

Our Values:

• • We are dedicated to providing our clients with the most comprehensive description and analysis of gemstones and jewelry currently available in the industry.

• We are committed to providing our clients with an accurate, unbiased and impartial evaluation, as well as education, counsel, and guidance.

• We adhere to the highest professional standards of appraisal theory and practice as mandated by the National Association of Jewelry Appraisers.
