"There is an enormous, and I mean enormous amount of pressure in all the cutting centres of the world to maximize the yield or weight," Allan professed. NOTE: Assume that the ideal diamond proportions should yield a .90 carat (90 pointer). The cutter realises that the retailer has far more calls for 1.00 carat diamonds than 90 pointers. In nearly all cases the cutter will alter the proportions to use up more depth and push the top corners out to create what is called a "lumpy" one carat diamond. To reduce costs further, minimal effort is used for symmetry to create any fire. The cheaper cut will sell quicker in most stores and the cutter will rotate his inventory at a faster rate. In many of these sales, an accurate cut grade is not given to the consumer for fear it will reduce its salability.
