I’ve been using Rhino for a little over a month, mainly for jewelry design. I took an intro course, so I know the basics, but I’m struggling to model this ring with a bezel-set emerald-cut stone (photo attached).
Defined is the cut but perhaps not the exact parameters of the shape. This in general is important but perhaps more so in this case as the table tends to be [could be] prominent—>
Technically the “body” / “innards” of a cut and polished diamond is [a bit confusing] called the rough. That may have e.g. inclusions [a general term]. Irrespective, one may want a more square shape or rectangular as you have in your image.
From this perspective one might suggest that it is the modeling of the stone that is a primary challenge. And be a catalyst that inspires the setting to use—>
Taking into account / considering the interaction between the alloy and stone. In your image it looks to be a white Gold but could be Platinum. In either case given the apparent ct size of the stone [humm ballpark 250mg] An inclination would be to use an 18K Gold or Platinum. The White Gold could be Rhodium plated but not necessarily. However, although somewhat counterintuitive, a 14K gold could be used to gain the extra strength given a particular setting - and or the ring is worn daily the stone is really good, one does not want to loose it.
In materials Rhino gives reflective indexes [ a really nice feature]. Make a Physically based Material and you will see the IOR drop down tab.
So after a dive into the above, the design of the setting / ring band etc. As mentioned, lots of good tutorials and approaches to this part and as you seem to have discovered too.
