The height of a gemstone, measured from the culet to the table, divided by the width of the gemstone. The depth percentage is critical to creating brilliance and fire in a diamond, and a gemstone with a depth percentage too low or too high will lack sparkle.
The depth of the diamond divided by the average width.
The quotient derived by dividing a diamond's width by its depth. This formula is critical in determining a diamond's brilliance.
The depth percentage, divided by the width of the diamond, mitigates the brilliance and fire in the stone. A diamond lacking sparkle probably has a depth percentage that is too shallow or too deep.
Height divided by width. Depth percentage determines brilliance and sparkle.
Refers to the relation between how deep and how wide the diamond is. Depth percentage plays a role in determining the brilliance and value of the diamond.
The depth of the diamond expressed as a percentage of the Average Girdle Diameter (or Width for fancy shapes). When the depth percentage is too deep or shallow it will affect the beauty of the stone.
On a diamond grading report, you will see two different measurements of the diamond's depth-the actual depth in millimeters (under "measurements" at the top of the report) and the depth percentage, which expresses how deep the diamond is in comparison to how wide it is. This depth percentage of a diamond is important to its brilliance and value, but it only tells part of the story. Where that depth lies is equally important to the diamond's beauty; specifically, the pavilion should be just deep enough to allow light to bounce around inside the diamond and be reflecting out to the eye at the proper angle. Keep in mind, also, that a depth percentage that might be excessive for one diamond cut might be necessary for another type of cut. For example, a 75% or 78% depth in a princess cut diamond would be typical and quite attractive. However, a depth of even 65% would be unnecessary and even detrimental to a round diamond's beauty.
The height of a diamond (measured from the culet to the table) divided by the width of the diamond. The depth percentage is critical to creating brilliance and fire in a diamond; a depth percentage that is too low or too high will cause a diamond to lack sparkle.
The measurement of a gemstone's depth (top to bottom) in relation to its diameter (width of girdle). The importance of this relationship cannot be overstated, as it is responsible for refraction of light, hence, the brilliance and fire that a gemstone can display.
The depth of a polished gemstone measured from the table (top) to the culet (bottom), expressed as a percentage of the stone's diameter at the girdle, an important factor in grading proportions.
The height of a diamond divided by the width of the diamond. The depth percentage is one of the many metrics used to measure how well proportioned a diamond is cut, and consequently how much "sparkle" it will have.
The depth of a stone measured from the table to the culet, expressed as a percentage of the stone's diameter at the girdle, is a relationship used in the analysis of the proportions of a fashioned diamond.
