Hello everybody,
I am trying to CAD a ring with a small 2.5 mm cabochon. What should be the wall thickness in the bezel? I am thinking 0.35 mm.
thank you

You could go thinner above the seat but also think about castability.
Whatever you can cast and looks good with the stone and the rest of your piece. I have moved 1.5 mm bezel walls with a brass rod and a hammer. Others among us I am sure have moved even wider.
thank you. Do i need to drill a hole under the seat trough the shank, like I would for faceted stones? thank you
It depends on the stone you are setting. If opaque then you don’t. If transparent then you need a way to clean it from the back side.
I teach my students to make the wall thickness for their bezels no thinner that .5mm and not thicker than .7mm. I tell them I am always thinking ahead to how long the bezel will last before it needs to be replaced. I got my start in jewelry doing repair work. It really depends in part on what type of metal you are using for the bezel: silver, brass, gold (white or yellow because white will generally wear longer in my experience), platinum, etc.
Personally, I think the bane of fabrication is that damn pre-made, fine silver bezel strip you can buy anywhere. Yes, its easy to work with and lays down flat on the stone with a bezel roller … but it’s just not substantial enough for the long run. My preference is to cut bezel strips from sheet stock using a small shear. I do use .999 because I find sterling is kinda spring sometimes. Normally 20 gauge, but really you can’t get too thick (within limits) if the bezel ends up being a design element. Obviously … anything beyond about 18 gauge is going to be hard to deal with. I confess over the years I have used a ton of the pre-made stuff. I had a job doing production work and it was easy to just knock out stuff with bezel strip. I guess it just depends on the situation.
