Hi Tom,

I can tell you from personal experiance there was at least four Jewellers using MoI back in the very early days (V1)
Some of those like myself have continued with MoI but in my own case, I'm no longer using it for jewellery.
Most moved back to Rhino because R4 already had a lot of the dedicated jewellery based Plug-in's.
The "leader" of those jewellery Plug-in's was Matrix which had superior Pave scripts & used a custom version of V-Ray for rendering.

My question for you is are you creating a "real-world" CAD model or just a render with your resultant pave model?

HTH, Colin
