When I was getting married a few years ago I started down this path as well. However I quickly realized I wouldn't be able to get the quality I wanted so I ended up finding someone who would be able to 3d print and cast my design. There are casting houses out in LA that will accept a STL file and will 3d print, cast, and finish your ring for you. The price is very reasonable, just labor and a bit of a premium on top of the spot gold price.
Using that experience I ended up starting a side business where I sell custom designed jewelry. My most popular design incorporates my customer's fingerprints. I build a pipeline that lets me go from a jpeg or other image file of the fingerprint to a fully 3d printable STL file (mostly using the blender python API). Because there are so many casting houses in LA they compete to keep the prices down. My completely custom rings that I have cast in small batches (compared to the large chains), are still very cost competitive with the competition.
Do you have an image? I am struggling to imagine how/where you squeeze in a fingerprint unless it is really scaled down or some kind of wrap around the band.
Are the grooves deeply etched? Or coated with some kind of protective layer? I imagine a few years of friction would rub away the finer details.
You leak your fingerprints every time you touch a smooth surface; one extra copy on an unlikely-to-be-lost item doesn't really increase your risk much.
I never wear my rings places where I don’t also bring my fingers, and rings don’t leave oily prints like my fingers do. Sarcasm aside, I’m not sure how this is a security risk.
In 2014[0], someone stole the German Defense Minister's fingerprint from a picture. We are well past the point where you can assume your biometrics are secure.
I guess you can go ahead and take "criminal mastermind" from your CV! Why would I think that a physical 3D object with the pattern of my fingerprint that can be carried around and held up to anything might possibly be a security issue? Nope, I can't think of anything...

Careful, your sarcasm is dripping!

Have you looked at the image of the ring? How do you plan to scan that anywhere?
