Do you think it is possible ?

That particular ring is cast, I think, rather than engraved.
You can certainly engrave signet rings on a Nomad, and probably on a Nomdad as well (sounds like a hungry father)
The effect might be closer to this sort of thing, however:

Those threads may be useful:
Hello there Kristiyan.
I think the time you’re going to see is going to vary depending on the shape and then also the features to be machined. Winston has some pretty good videos on this topic that I recommend you check out:
and
In the second video it looks like the total time is 37 minutes. That’s quite conservative, because he’s using a super small endmill that is more fragile, but also wont turn as much material into dust that might be hard to collect.
So if you were to do a simple sq…
I’m using a Nomad for cutting recesses in pure silver and then applying vitreous (glass) enamel into the recesses. There have been some challenges and a learning curve. But I’m now to the point of getting some pretty good results.
I cut the recess about 1/2 the depth (0.025") of 16 gauge (0.050") fine silver. I use a 1/8" end mill (#102Z) for the larger areas followed by 1/16" (#112Z) and 1/32" (#122) to define the sharp interior corners. I hold down the silver sheet with the blue fixturing wax…
And this video is helpful to have a sense of scale of the tiniest details one can pull off with a Nomad:
I’m no jeweller and I don’t even own a Nomad, but it seems to me that such a ring would be doable in tems of level of detail. A specific jig would probably be required for workholding (such that the top ring surface is kept perfectly square to the spindle during machining).
What piece of stock would you start from ? Do they sell un-carved ring blanks ?
