Diamond Depth

The measurement of the diamond from the table to the culet, expressed in millimetres. The depth percentage is the ratio of depth of the diamond to its diameter. The ratio of the depth of the diamond to its diameter. This means how deep the diamond is in comparison to how wide it is. The depth percentage of a diamond is important to its brilliance and value. The diamond’s 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. A good depth percentage will differ for each diamond cut.
