Diamond Valuations: FAQs

To ensure the most accurate grading of your diamond and to receive the highest offer, your diamond is evaluated with a 10x power gem grading loupe. Diamonds without credible certificates, such as G.I.A., should be removed for the most accurate evaluation.  With an accurate evaluation, we can provide you the highest possible offer, which is based on market prices and demand both locally and internationally. The process takes a few moments.


1. Carat Weight: The value of a diamond increases per carat as the weight increases.

2. Color Range: From colorless to intense fancy yellow.

3. Clarity: The number, size, position, type, and color of the flaws, inclusions and blemishes.

4. Cut: The overall proportions, symmetry and finish.

5. Proportions: Table size, crown angles, and pavilion angles.

6. Measurements: Length-to-width ratio of fancy-shaped diamond.

7. Shape: Fancy shapes value 15% to 40% less than round.

8. Symmetry: The upper part of the diamond (crown) and the lower part (pavilion) how angles match up.

9. Depth Percentage: The ratio of the total depth of the diamond (from table to culet) as compared with

     the total diameter (which is used as the 100%).

10. Table Percentage: The ratio of the table width as compared to the total width.

11. Polish: Well polished diamonds allow more light to enter and exit.
