Hi Roupey, about facing up smaller...I can understand why some of the users here might say this WF diamond would face up smaller - the depth is 62% and the girdle is slightly thick. However, think about this for a minute. The formula for calculating carat weight from measurements for an ideal cut RB is:

diameter x diameter x depth x 0.0061 = carat weight

For a 0.582 carat diamond that is cut to the Tolkowsky depth of 59.3%, the diameter would be:

diameter x diameter x 0.593 x diameter x 0.0061 = 0.582

(diameter)^3 = 160.8935

diameter = 5.44 mm

This WF diamond is 5.33 mm on average, so it faces up like a 0.55 carat Tolkowsky. Is this enough to kill a sale on a beautiful diamond? Do you think you will see 0.1 mm?

This diamond faces up a little smaller than the first JA and a little bigger than the second. If you don't care about upgrading, maybe the G VS1 JA diamond is the way to go. If you do care though, WF has a better policy.
