Flawless diamonds are quite rare, and as a result are graded the highest. The clarity of a diamond is the grade of a diamond’s rarity and purity. It’s this brilliance that creates the sparkle. The more the diamond reflects, the more brilliant it is. Brilliance is the diamond’s ability to reflect light – specifically white light. This is very similar to how the sparkle of a diamond works, just on a much smaller (and more luxurious) scale. However, with hundreds of facets, each different from the one next to it, light bounces off in all different directions. This is similar to a disco ball: if it was one smooth, reflective ball, light would only bounce off in one direction. This means there are more angles and opportunities for light to hit the stone and bounce off the surface. To give a diamond the best opportunity at producing sparkle, facets are cut into the diamond. The more opportunity the diamond has to do this, the higher the level of sparkle the diamond will produce.
