How to achieve this effect?

G’day - hoping someone can give me a steer on how to achieve something in Rhino. I’ve been trawling the forums and youtube for the last couple of days but so far I haven’t had any luck!

Basically, what I would like to do is ‘engrave’ a ring with a crest on top. Something like this:
crest3

I have a ‘relief’ of the crest I would like to use in OBJ and STL formats. I had assumed I would be able to import into Rhino and then Boolean Difference the relief from the ring to create the effect however I’ve realized that probably isn’t going to work.

Any direction on how to achieve this would be appreciated. I haven’t been able to find anything but it’s likely i’m looking for the wrong things.

Many thanks!

Displacement maps might work:
