What depth should a round diamond be?

Round cuts, well respected for their brilliance and fire, require a depth range of 61% to 62.5% in proportion to a table range of 54% to 57%. This adequately allows light rays to travel and be reflected within the cut without leakage to deliver their highly acclaimed sparkle.
