Can you give some tips on this ring?

Hello Everyone,

Can you help me on this project? I’m kind lost doing the top surface. I tried different cutters and Boolean difference, but the results are very far away from this design.

Kind regards,
Armindo

maybe you have a file you made so far? lazy booleans might just not be the right way to go here, it looks like you have to simply build it all from scratch, which well is not that complex, just a bit of foot work placing the points where they should be.

I tried to do it by hand, but the surfaces were not flat. Do you know how can I make them flat instead of wavy?

The image you posted is the reference or the one with the problem ?

The image is what I’m trying to achieve

Hello, this is what I’ve done so far.
