The Evaluation Process for our Certified Diamond & Gem Jewelry Appraisals

An Accredited Evaluation Process that Certifies Your Jewelry Appraisals

 

Diamond Grading: All diamonds over 1/2 carat will be issued a diamond grading report.

Clarity:  An essential part of the Jewelry Appraisal  process requires us to judge the internal characteristics (or inclusions) under a high powered gemological microscope. We use a plot diagram to show the location and type of inclusion. A clarity grade using the GIA clarity grading system will be assigned and noted in the report.

Color analysis: The amount of inherent color in your diamond will be evaluated and compared to GIA master graded diamonds under proper daylight diamond grading lamps. We then assign a letter grade for your color type using the GIA color grading system and this is noted in the report. Our lab has a full set of master graded diamonds graded and certified by the Gemological Institute of America (GIA) which we use for comparison.

Carat Weight: If your diamond is mounted, the carat weight is estimated during the appraisal process by using a standard formula for the type of cut for your stone. If your stone is un-mounted, it is directly weighed on a digital carat weight scale. The actual weight will be noted in the report.

Cutting Proportions:  As part of the appraisal, the cutting proportions of your diamond are evaluated. This includes measurements of the diameter or length and width, as well as the depth of your diamond. Depth%, Table%, Crown Angle, and Girdle Thickness are all evaluated and noted in the final report.

Finish: In the Jewel Appraisal process, symmetry and Polish will be assessed and given a grade of Poor to Excellent and noted in the report.

Cut Grade: A cutting class is assigned based on the stone cutting proportions and is noted in the report.

Fluorescence: Your diamond will be tested for a reaction to long wave and short wave ultra violet light. The findings will be noted in the report.

Enhancements: Any and all enhancements that are detectable by gemological testing will be noted in the report.

Colored Stone Grading: All colored stones over one carat will be issued a colored stone grading report.

Hue (color): A very important part of the Jewelry Appraisal process is the viewing of the color of your stone and then comparing it to a GIA master color comparison set to determine the stones color or hue. All this information will be noted in the report.

Saturation of Color: The saturation of color inherent throughout the stone is evaluated and noted.

Tone: We use our Jewelry Appraisal expertise to examine the degree of lightness or darkness of the color of the stone. Once evaluated, our findings are noted in the report.

Carat Weight: If your stone is mounted, the carat weight is estimated by using a standard formula for the variety and cut type of your stone. If your stone un-mounted, it is directly weighed on a digital carat weight scale. The weight is noted in the report.

Cutting Proportions: Depth%, Table%, Girdle thickness are evaluated and noted.

Cut Grade: Cutting class based on the stones cutting proportions is evaluated and noted in the report.

Clarity Type: The clarity type is noted for your variety of colored stone.

Clarity: A clarity grade is assigned that is appropriate for the clarity type for your stone and noted in the report.

Finish: In our Jewelry Appraisal service, symmetry and polish will be observed and given a grade of Poor to Excellent and noted in the report.

Enhancements: Any and all enhancements that are detectable by gemological testing will be noted in the report.
