Perfect Diamond Dimensions Round

In 1919 the mathematician and renowned gemologist marcel tolkowsky published his findings for the perfect diamond proportions in his thesis entitled diamond design a study of the reflection and refraction of light in a diamond all diamonds that were within the parameters of the so called tolkowsky ideal cut were considered to have an excellent light return.

Perfect diamond dimensions round.

Please note that gia does not assign a cut grade to fancy cut stones such as princess cut or cushion cut yet but still these proportions are critically important in analyzing the cut. Marcel tolkowsky revolutionized the world of round brilliant diamonds in 1919 when he published his landmark book titled diamond design. For a princess cut diamond choose a diamond with an ideal depth of 68 to 75. This is exactly what you are looking for in a beautiful diamond.

If you have a stone with perfect diamond proportions the diamond will refract the light in an excellent way. The tolkowsky ideal cut. In his book he wrote about a set of proportions that would yield in a diamond with maximum beauty fire and scintillation based on mathematical calculations. Ideal cut diamond proportions and brilliance.

In the first section we will provide our best summarized insights on ideal proportions for round and non round fancy shape diamonds. It will therefore exhibit a lot of sparkle brilliance and scintillation. The round cut diamond is the most popular diamond shape representing approximately 75 of all diamonds sold. Due to the mechanics of its shape the round diamond is generally superior to fancy diamond shapes at the proper reflection of light maximizing potential brightness.

You might have heard about the fact that the exact diamond proportions determine the cut of a diamond. However if the proportions of a diamond are. This article has two sections.
