Now, with all the technical specifications laid out, you might assume that all the diamonds in the market should be polished to ideal proportions if cutters simply followed a standard formula. In order to confirm light performance, you will need to rely on idealscope or ASET images for analysis.Д«вЂ™s Ideal Cut Proportions for Round Diamonds Here, I want to highlight that proportions should only serve as an initial filtering process. It will not only help you save time but weed out the badly cut diamonds as well. I strongly recommend that you apply these parameters when searching for your own diamonds. This tighter set of parameters helps to filter diamondsВ that are the cream of the crop and I personally use it to handpick diamonds for myself. While it is modeled after TolkowskyвЂ™s initial findingsВ andВ studies from GIA/AGS, my parameters are much more stringent. Over the years of examining and analyzing diamonds, I had tabulated my own set of parameters for selecting a ideal cut round diamonds. My Personal Criteria is Even Stricter Than Both GIA & AGS Labs They offer the best cut quality diamonds in the world and a wide range of high quality engagement ring settings. If cut quality and the sparkle factor of a diamond matters to you, I recommend that you visit White Flash and Brian Gavin Diamonds.

You can download the AGS cutting guidelines here and GIA proportions chart here to do your own comparisons and analysis. However, it has now been scientifically proven that an ideal cut could have proportions outside of this value and diamonds with slightly bigger tables can also achieve ideal optical properties.Д«oth GIA & AGS had also came up with comprehensive tables of proportions and cutting guidelines. In TolkowskyвЂ™s initial publication, he stated that the ideal cut diamond should only have a table proportion of 53%. If you are looking for a diamond that exhibits superior brilliance and sparkle, scroll down to use MY proven table of ideal cut diamond proportions instead. With modern day research, the Tolkowsky proportions have been further refined. *Note: The above historical table should be used as a reference only.

GeneralВ Proportions For Round Brilliant Cut From Tolkowsky In fact, a diamond could be polished within aВ range of proportions and it would still display ideal optics. One of the major breakthroughs made was theВ discovery thatВ ideal cut diamonds do not have to follow a single set of proportions as set forth in TolkowskyвЂ™s original dissertation. With the help of specializedВ studiesВ and technological advancement, researchers fromВ GIA & AGS had publishedВ scientific journals that changedВ the way we polishВ and buy diamonds. In more modern times, much has changed asВ TolkowskyвЂ™s groundbreaking discoveries were further developed upon. Marcel TolkowskyвЂ™s ideal proportions for a round brilliant diamond. Ever since the epic publication, TolkowskyвЂ™s findings were widely applied in diamond polishing by cutters around the world. 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. A larger carat diamond with a poor cut grade can appear smaller than a diamond of the same size with a higher cut grade.Marcel Tolkowsky revolutionized the world of round brilliant diamonds in 1919 when he published his landmark book titled вЂњ Diamond DesignвЂњ. It is important to consider carat and cut together when buying a diamond. This means that even two diamonds of the same carat weight will most likely differ drastically in value. Carat weight has a large impact on a diamondвЂ™s value, along with cut, colour clarity and certification. The value of diamonds per carat can vary massively depending on the other specifications. Dimensions are a good indicator of how well a diamond has been cut for it to reflect the maximum amount of light. Ideal diamond dimensions are different for every diamond shape. For example, a 1ct round diamond would ideally measure around 6.5mm in diameter, a 1.5ct around 7.2mm and a 2ct diamond approximately 8mm. The size dimension of a diamond for its weight is a good indicator of its value and desirability. One carat is equal to 0.2 grams, and one diamond carat is divided into 100 points, meaning that 0.25 of a carat is 25 points or Вј carat. This means that the larger the carat, the heavier the diamond will be.

Diamonds are measured in carats, which refers to the weight rather than the actual size of a diamond.
