Crown Height

Ideal diamond Crown Height may vary depending on the shape of the diamond you choose. Crown height percentage is calculated by dividing the actual height of the crown by average diamond diameter or width. Measurements are rounded to the nearest .01 millimeter.

The crown is the height of the diamond from the girdle edge to the surface of the table facet. Crown height can effect both the dispersion and brilliance of a diamond.

The Ideal Crown Height for a Fancy Shape Diamond may vary from that of a Round Brilliant Cut diamond. Please ask one of Droste's Certified Gemologist-Appraisers to guide when selecting the proper crown height for a Fancy Shape Diamond.

The AGS Ideal 0 Cut grade for a Round Brilliant Cut diamond includes a narrow range of crown height from 15 percent to 16.2 percent.

Round Brilliant Cut Diamonds with Ideal to Very Fine cut proportions have a crown height between the ranges of 13.1 and 16.2 percent.

It is difficult to visually recognize differences in the appearance of diamonds that have crown height within the range of ideal to very fine. Diamonds that have crown height percentages that are lower than 13 percent often have larger tables. This often produces less brilliance, less dispersion and fire. In contrast crown heights that are greater than 16.2% give the diamond a lumpy, top-heavy appearance, and disrupt the balance of fire and brilliance.

Fancy cut diamonds with very fine to ideal cut may have crown height percentages that are different than round brilliant cut diamonds. If you have questions regarding the proper crown height of fancy cut diamonds, please contact one of Droste's Certified Gemologist-Appraisers and they will be happy to answer any questions you may have..
