Depth
The depth percentage is the height of the Lab-Grown Diamond (measured from the tip of the culet to the table) compared to the diameter of the Lab-Grown Diamond (the top of the Lab-Grown Diamond measured through the middle from one edge of the girdle to the other). To avoid buying a Lab-Grown Diamond that loses light out the bottom, look for a Lab-Grown Diamond in which the height measures between 57.5% and 64.5% of the total Lab-Grown Diamond width. You'll find this measurement on the Lab-Grown Diamond certificate..
