ABOUT DIAMOND CALCULATOR

DiamCalc is a great way to learn about diamond cut quality. You can experiment with a virtual Ideal-Scope on different diamond proportions and instantly see what works and what doesn't.

The information that is readily available on a diamond certificate, like size, weight, table% and girdle thickness is enough to build the diamond and see what it might look like. You will quickly see if the stone can look good or not.

You can also model ray paths through the diamond and see why and where it leaks light, or reflects it back to you in multi colored rainbows.

DiamCalc is a spin off product from the pro's and scientists at Moscow State University (MSU). It's no surprise that the Russians developed a product like this; I think they teach math and physics to 5 year olds.

The MSU researchers and OctoNus developed DiamCalc as part of their computer modelling study into the effect of proportions on the optimal brilliance and fire in round brilliant cut diamonds. The first results were published in 1999 on their website that you can get to at www.cutstudy.com/cut/indmex.htm which has become one of the worlds most accessible and amazing resources.

DiamCalc2 lets you do all sorts of things, like import a full 3D scan of a diamond from a Sarin proportion machine that more and more vendors can email to you. This means you can have a virtual diamond that you are considering buying inside your computer. You might want to run a cut quality scan on the stone and see how it's light return, leakage and contrast compare to a 'Tolkowsky' proportioned standard stone as well as make movies with the diamond rocking from side to side. At the press of a button, in 2 seconds, there is an Ideal-Scope image of the diamond.

DiamCal is used now by many experts and labs including GIA(1) and myself (Garry Holloway) who are involved in the advancement and understanding of diamond cut and cut grading systems.
