It can be done, I regularly do for jewel.
Let me know if you want the print of the 3d for manufacturing.
Or just rendered and you want to show it for showcase.
For purpose for production, we can do that as it only needs rhino which we are not proficient.
But for showcase, 3d model rendering , using vray , texturing lighting etc. We are very much pro.
Can show you some.
Let me know
