This is a part two of possibly a series i’ll try to make about different crystals
This time I chose the Rose Quartz, also known as Heart Stone or Love Stone.
I started of with two tutorials as resources. One for the modeling of the crystals in Blender.
After that, the real challenge was the material shading. On the first part of this series I made a very basic crystal material.
Then I found another awesome tutorial by Gleb Alexandrov
however his tutorial is meant for Cycles render, I use V-ray, so I had to follow the tutorial completely on cycles, and then translate the effects and behaviors the light has on the cycles material into a V-ray Material, which was absolutely time consuming, but totally worth it, I developed an in depth understanding of vrmats refraction, and translucence.

I made a variation of the Ice material to appear more like a Rose Quartz.
Looking back at it, I believe I should have added a bit more Translucency and less refractions, to make it more solid looking, and the tone its a bit redish instead of salmon, but it ended good enough on the final picture.
Scale is a big factor on this shading, bigger crystals (below) give thicker and foggy crystals, while small crystals tend to be more refractive and clear
Lastly I needed to get a render pass of the shadows of the skin and the caustics caused by the crystals, this helps incredibly to blend the effect and make it less choppy and CG looking.
