This is beyond incredible, wow!Sako from CJD Sako on Instagram. He could do it.
Look at what he made for @elizat
A Resplendent Ruby and Old Mine Cut Diamond Ring by Old Miner Jewelry/Sako
Forewarning- this will be a bit of a story. Photos will follow, of course. This is probably my longest running project. I have always loved a ring that featured an old cut oval, in an emerald halo, which the owner calls Gilda purchased from Jewels by Grace. If you "know" Gilda, you get it...www.pricescope.com
Here is @elle_71125 ring. This is by David Klass but it is a lot more complicated than what you are after so I would say he would be a good fit as well.
