Every Lumina Diamond is cut for maximum beauty, not weight. Because more of the original rough diamond must be sacrificed to achieve an ideal cut, only a small percentage of diamonds are cut this way.

All diamonds have some brilliance, but an ideal cut diamond will offer the maximum balance of brilliance, sparkle and fire. When you buy a non-ideal cut diamond, it will have been cut to retain the maximum weight from the original piece of rough diamond. The extra depth of a non-ideal cut diamond may increase the carat weight of the diamond, but the play of light and sparkle are reduced.
