I saw this article from the American Gem Society recently and I thought it would be a good way to explain the detail and specifications behind the real world facet design of a brilliant square cut gemstone. This article is about testing and evaluating the “light performance” (how efficiently the gem reflects and refracts the light from the point of view of the viewer) of this gem facet design.
So, when we say that the gemstone models offered by 3d Model Forge are reflective of real world designs, compare the two images above and see for yourself the similarity in the patterns reflected inside the gemstones. Yup. They match!
