The Round cut diamond precious stone is the most frequent cut and has brought the most attention in the trade but not popular as princess cut diamond. Right now there are various other reduces for both round and fancy shaped diamonds. This kind of article only relates to Round Brilliant cut diamond jewelry.

Numerous Round Brilliant Reduces have been defined over the years, each with their own detailed requirements of the various amounts of the diamond. The main aim of these slicing styles has been to maximize the Fire and Brilliance of the precious stone to produce the most beautiful stone possible.

Tolkowsky Ideal Cut

In 1919, Marcel Tolkowsky systematically assessed the optics of the round brilliant precious stone using mathematical calculations that considered both brilliance and fireplace of diamonds. He believed the best proportions for cutting round brilliant expensive diamonds.

Tolkowsky published his conclusions in his book "Diamond Design” He is generally acknowledged as the father of the present day circle brilliant precious stone cut. Modern-day standards for "ideal cut" diamonds are generally based upon Tolkowsky's findings, with minimal changes.

Hearts and arrows

Various other Cuts

There are plenty of and mixed 'cuts' described in the marketplace. Some are medically determined and some are not specified in any way. That they are merely marketing conditions attached to 'all' expensive diamonds sold from particular vendors.

Certification cut grade

Several precious stone grading laboratories will note a 'cut grade' issues certificates. Each clinical works to an identified set of parameters to evaluate the proportions of the diamond. These amounts are then given a grading depending how close they are to those defined parameters.

It is important to note that the cut grading variables vary across laboratories. To get example, the AGS and DCLA laboratories base their parameters on the Tolkowsky Ideal even though the GIA have developed their own lower grading system.

Regardless of research laboratory, the higher the minimize grading, the closer the stone is to the 'best' cut as identified by that laboratory. Because of this diamonds with a higher cut grade 'should' perform better with regards to Fire and Brilliance. Sadly this is not always the truth.

However, some precious stone marketers have used their creative certificate together with the actuality all diamonds display some sort of Hearts and Arrows and market their diamonds as 'Hearts and Arrows. ‘This problem is further compounded by the reality that there is no final industry consensus where diamonds can be called Hearts and Arrows and which cannot.

Another problem with picking a precious stone structured on a named minimize is each cut is defined with some kind of private preference in mind. For example the European market historically likes a rather larger stand to the American market. The popular cuts in the respective regions indicate these preferences.
