I wonder if the problem is not with 3D Interconnect?
Try to disable it by unchecking this box:

Sbadenis, my pieces only contain volume bodies, but it's true that I added stones to the jewelry (which I downloaded), and I believe that there are surface functions. Do you think that's the problem?
I'll also try converting it to xt, what is this format?
Stepbeno, I'll also look at this 3D interconnect, thanks for this track

The Xt is the parasolid motor (Siemens) behind SolidEdge, SolidWorks and Topsolid see other software.
The step is better known but the 2 are exported and imported very well in SW to SW.
If necessary, try to put your stone in the delete state to see if it works, if it is the case, it is your stone or stones that are blocking the export.
Okay, I'll try all of this and I'll tell you 
It worked! 
It is indeed the 3d interconnect that was the problem for the step files, thank you stefbeno!
And nickel for the xt, with or without 3d interconnect, it worked well, thank you sbadenis!
On the other hand, it didn't keep me looking good, but I imagine it won't be very complicated to put it back on
I can't wait to be able to put all this in the school machines, thank you all very much for your help and patience
