The brilliance of your diamond will be determined by its cut. The geometry isn’t a secret, so don’t be misled by all the hyperbole about “master cutters” and other such nonsense. The simple reason that 99.71 percent of all diamonds are cut incorrectly is that diamonds are sold by weight and at $850,000 an ounce, there is powerful temptation to fudge the alignment of the facets so that the finished diamond will be heavier. The diamonds that are cut properly are the ones whose natural shape makes it possible for the diamond cutter to maximize their weight without misaligning any facets. The buyer who gets “first look” at the freshly-cut diamonds will always choose the ones whose natural shape made it possible for them to be cut for maximum brilliance. And that is the pedigree of every Spence diamond.

Buying Tips

  • Cut is the most important of the 4Cs because it has the greatest influence on a diamond’s sparkle.
  • Even if a diamond has a perfect clarity and colour grade, if it has a poor cut, it may appear dull.
  • When diamond cuts are made with the proper proportions, light is returned out of the top of the diamond (which geologists refer to as the table). If the cuts are too shallow, light leaks out of the bottom; too deep and it escapes out of the side.
  • To maximize your budget, choose the highest diamond cut grade your budget allows. We suggest a cut grade of Very Good or better.
