How to render a diamond or other gemstone?
Many thanks to Blender’s developers. If the gemstone will be part of a larger scene where other elements do not require such a high sample count, you can keep the gemstone on its own Render Layer to keep render times from becoming ridiculous. (Okay, I mean keep them less ridiculous.)
Which is better man made or lab created diamonds?
Lab created diamonds are a responsible choice given that no mining is required. Man made diamonds have the same physical, chemical, and optical properties as mined diamonds. Lab created diamonds offer excellent value, and are slightly more affordable than natural diamonds of comparable size and quality.
What makes a fancy colored diamond lab grown?
Lab grown fancy colored diamonds are formed when small amounts of specific trace elements are present during the growth phase of the diamond, just like in nature. In both white and fancy colored lab diamonds, the exact composition of trace elements may differ from their natural diamond counterparts.
How are simulant diamonds different from natural diamonds?
Simulants do not have the same chemical and physical properties as natural diamonds and therefore sell at much lower prices than man made diamonds. Simulants can be distinguished from natural or lab grown diamonds using only the naked eye.
How to create a diamond mesh in Blender?
A page on diamond.com has diagrams that explain this really well: Luckily, creating an ideal diamond mesh can be done in Blender in an instant. Just enable the Extra Objects (Mesh) add-on, and it will be an option in your Add Mesh menu. Now pressing Shift A in the Viewport gives you new options:
What is the IOR and dispersion of a diamond?
The IOR of diamond is 2.4175 and the dispersion is .044. So by using these values, as well as a realistic diamond size, we can get something much more accurate. Make sure to apply the scale ( Ctrl A) of your diamond object if you want the refraction to be as accurate as possible.
How does geometry affect the appearance of a diamond?
With gems like diamonds, the cut determines the way the light gets reflected. Geometry plays an important role in the appearance of this material. A page on diamond.com has diagrams that explain this really well:
