Chipped Diamond Re-Cut
Calculating the weight loss in re-cutting a chipped diamond is possible with some measurement. If the angles are acceptable on a chipped modern brilliant, then these won’t have to be considered. Often a buyer or cutter will re-cut the stone, removing the chip and also improving the proportions at the same time. Many times a chip occurs due to the acute angle left by the original cutter when leaving the crown and pavilion very flat. The more acute the crown and pavilion are in relationship, along with an extremely thin to very thin girdle, the more likely a girdle chip will eventually occur when the diamond is worn. In this scenario, the cutter or buyer will possibly want to improve the proportions in the re-cut process as well.
