Learn about Depth Percentage

The depth of a diamond is very important to its brilliance and value. A diamond that is cut to Ideal or near Ideal depth percentage exhibits a balance of brilliance and is more valuable. Diamond cutters must remove more weight from the original rough diamond crystal to cut a diamond with proportions that produce great brilliance.

Diamonds are very rarely cut to exactly a 61% depth percentages. Fine cut diamonds have total depth percentages between 59% and 63%. Diamonds within this range provide excellent brilliance. Diamonds that have depths outside these ranges cost less, but a degree of brilliance is lost as depth moves away from the preferred 59% - 63% depth percentage range
