Are brep normals pointing outward or inward?

Your stone geometry is flipped inside-out.
If you convert it to mesh and bake the mesh, this is the result:

If you bake the polysurface, it is baked as “positive” solid, and make correct solid booleans on rhino.

On grasshopper if you [DeBrep] and then [Brep Join] your stone will become correct (a “positive” solid) and so you can make solid operations/booleans.

Your brep internalized on grasshopper is flipped: (If you bake it, it is fixed automatically…)

Check the method which it was created.

sorry but that doesn’t happen on my pc
the normal ones appear correctly.

I said i converted to mesh your stone, and baked the mesh.

Then, see my last pic: do the same, evaluate the normals (of random points) of your stone brep.
It is flipped inside out.

Fast solution, on gh, is to “explode” and re-join the brep of the stone… to ensure the “positivity” of the solid.

okay thanks.
that gem comes this in peacock component Cabuchon studio.

but now I find how to modify that arc of the ring

I’m not sure about your question, your ring solid have intersecting surfaces.
You should contact those cluster’s creator to see how to edit the shape…
