Following is a look at how the depth of the stone influences the
cushion cut.
Too Deep
This type of
diamond looks very small in relation to its
carat weight. If the
diamond were too deep, you would not be able to show it off to good effect. The weight would be mostly distributed towards the bottom, but the opposite is what you want for a bigger look. For instance, a
2 carat stone could end up looking the same size as a 1.25-
carat diamond.
Too Shallow
This type of
diamond appears to have a dead spot right in its
center, thanks to
light getting out through the bottom instead of reflecting out the top the way it should. The best
diamond would have the right proportions to facilitate entry of light into the
stone, as well a reflection backs out the top, delivering a
brilliant sparkle.
