The Process
Initial consultation
What is a professional appraisal? The process begins as a consultation to determine the 'purpose' and 'function' of the appraisal, which in turn determines the approach to value. This usually answers the questions to the nature of the value placed upon the item(s) to be appraised. These issues directly affect the realm of 'value' needed to pursue the facts regarding the items to be discussed.
Taking-in Process
For protection, when you leave your valuables with us, we will document all pieces to give you a detailed receipt. This documentation would include the plotting of all major diamonds and color gemstones and also include a pictorial record for a better description. When you come back to pick your jewelry, we will match the diamonds with the original plotting we gave you. In addition, you would like to know all your valuables are protected by our insurance company.
Our Internal Research & Procedure
After the initial examination, the items are researched, pertinent information required to conclude the appraisal is gathered, and a value is assigned.
The appraisal analysis, opinions, conclusions, and report will be prepared in conformity with and subject to the following:
- According to the American Gem Society Standards which are the highest in the jewelry industry.
- The International Society of Appraisers.
- The Uniform Standards of Professional Appraisal Practice (USPAP) of the Appraisal Foundation.
- and The Principles of Appraisal Practice and Code of Ethics of the American Society of Appraisals.
- Guidelines for Insurance Replacement Cost documentation as published by the Jewelers Vigilance Committee Inc.
- And with the application of the techniques and equipment recommended and used by G.I.A.
Our three major appraising goals
- An estimate of value for the intended use of the appraisal report.

- Provide you with a professional appraisal report, with very detailed gemological information to avoid unnecessary issues with an insurance claim or for any other intended use.
