I’m playing with Rhino 7 Cycles render, using existing materials and environment.
This looks really good…how do you get the gems you need in Rhino? I have the gems in 3dm but to get all the colors is an issue for me. Like where do you apply the diamond decal or pic,?
@t.shinya- These are gorgeous! What parameters did you use? Like, environment and materials? Show me your ways!
I’m still learning and haven’t used many features yet, but here is my sample scene and setup.

To be honest, I’m not sure.
Rendering a diamond is a tough one.
For this rendering, I just used the sapphire material under gem.
you could play with the index of refraction in a glass material. Typical glass is around 1.5 and diamonds are around 2.4.
So beautiful ~
Russ, as long as the 3dm files you have are mathematically modeled after the proper cuts of the gemstones, using the default gem material with raytracing will product a fantastic result.
Here is a link to a render i did a few days ago
Thanks a bunch…just trying to get the best way. Recently watched a video on this using Rhino 7
Oooooooh! That is a delightful bit of filigree.
Is this NURBS or SubD?
This was originally built with T-splines and converted to SubD using Rhino 7.
I needed a model for a model to test Cycles render.
I couldn’t resist to throw your file at Maverick render. Just changed the materials to the build-in ones and used another lighting setup. I am still beginner in Maverick, but here is the result (2 minutes preparation and 10 minutes rendering on my very weak card).
@nathan can you take a look at this?
I tried to recreate the image above and swaped from gem to PBR, but it appears Clearcoat amount isn’t registered with Cycles. No changes, no update if I up it to 10.

As a curiosity I did a direct comparison between Cycles and a full caustics renderer like Bella. Turns out cycles is pretty darn good. You do get more indirect bounces inside the sapphire with Bella, so there is a little more vibrancy there, but overall close.
Wow, that is really nice! How did you manage to get so much reflections internally?
Is it mainly due to another HDRI?
I see Bella has that extra spark in the reflection on the gem, That’s what I tried to achieve with ClearCoat. Did you use the basic Gem material or something else?
And did you use linear fall off on the lights, or just the HDRI?
@Holo With Cycles all lights were left to their defaults (“constant” falloff). There is no HDRI. The gem is a basic glass material.(didn’t use gem material).

It looks amazing!
Thank you for sharing the file!
