DiamCalc is a system for cut gemstones modeling, which enables many different users to achieve their goals. The real (photorealistic) image of a polished diamond created by the system makes it possible to determine the cut properties that often cannot be measured and to find the optimal combination of cut parameters that would provide the best perception, brilliance, fire, scintillation and others of the stone.
Photographs do not adequately show the sparkle and brightness of a real diamond; until now. DiamCalc since version 3 has High Dynamic Range (HDR) imaging that shows the intense sparkles on your computer screen by reproducing the flares or bloom that we see in real diamonds. Bright sparkles often appear to be larger than the facet they emanate from, even extending outside the edge of the diamond.
Scintillation is the last great frontier of diamond cut studies. Regular ray tracing software and lab grading systems have failed to model scintillation and capture this bloom factor.
Now buyers and sellers can realistically show a client, or visualize a distant diamond themselves before buying it. They can see just how it will look as they rock it from side to side in their own environment and even make promotional videos for individual diamonds.

DiamCalc’s High Dynamic Range lighting can come from a variety of panoramas such as a ball room, forest or hillside so anyone can see how the diamond will look in each of these environments. Jewelers of the future will no doubt import panoramic images of their own sales floor into DiamCalc.

The result of new technologies is the highly photorealistic images reflecting both non-trivial optical properties of gemstones and compound features of the environment.
The Diamond Calculator is designed for jewelers, diamond graders, and sale specialists dealing with diamonds and diamond jewelry, for companies active in designing special cuts, manufacturers and technologists.
There are advanced professional versions of Diamond Calculator:
DiamCalc Pro and DiamCalc Color. The DiamCalc Pro is developed to help designing new cuts and optimize existing cut proportions to achieve the best cut qualities. DiamCalc Pro software aids quantitative and qualitative cut performance assessment by outputting into simple text reports that are powerful when made into graphical charts, and images presented in 2D html tables with selected proportion ranges.
DiamCalc Color is an exclusive advanced professional version of DiamCalc software. This software is restricted in its availability on personal request. It is developed especially to optimize the proportions for cutting the best possible fancy color.

Main features of DiamCalc
- Precise calculation of a stone weight by taking into account all main parameters, such as diameter, total depth, girdle thickness, pavilion depth, crown angle etc.
- Generating 3D images and movies of polished diamonds:
- High Dynamic Range photorealistic images and movies. Light absorption, repeated reflections, dispersion, variable lighting, High Dynamic Range panoramas, real observers and many others are used in images rendering.
- Outline framework models and refraction models, which show refractions of back facets seen through front facets
- Stereo mode - three-dimensional images of diamond that can be seen with a pair of stereo glasses
- Stars and bloom effects
- Inclusions rendering
- Non convex cut renderings
- ETAS and DETAS images, statistics diagrams
- QuickTime movies and export it for ipod / iphone
- Possibility to work with the main diamond cut styles: Brilliant,
Oval, Marquise, Pear, Princess, Baguette, Happy-8, Emerald, Flanders, Heart, Radiant etc.
- Loding external dll cuts, scanned mmd and srn cuts, asc, etc.
- Creating new variable 3d models of diamonds by Cut Designer
- Determination of fixed or variable parameters
- Determination of parameter combinations for diamond grading, including GIA, HRD,
AGA and Russian TU systems. Evaluation of the defects deteriorating the diamond perception
- Price lists. Prices calculation based on color, clarity and fluorescence.
