The most important factor in choosing your diamond is cut.
The cut is the only detail over which man has control.

Cut for Beauty The ideal cut diamond describes a round brilliant diamond that has been cut to exact and mathematically proven proportions. All of the light entering from any direction is totally reflected through the top and is dispersed into a display of sparkling flashes and rainbow colors.
Cut for Maximum Weight Most diamonds are 'spread' in their cutting to retain maximum weight from the original rough. A heavier diamond will result, but at a dramatic sacrifice of potential fire and brilliance.
