Amber would be my first guess too. Might be amber amber made of several pieces of amber pressed together. Very common. How does it react to a hot needle ? Provided that you can try in an hidden place of the material.
For the record, I don't think the example above is actually yellow jasper. Those flow lines do not look like patterning you'd expect to see in jasper, or almost any natural material. Also definitely not dino bone or brecciated jasper.

I did google Yellow Jasper rings and some are like that, Then again I don't know if there been enhanced in some way as you don't know now adays, Many do have flow lines as you say.
Id say ring could be egg yolk amber tbh. but that's my thought with googling cab rings, Thought i'd try and help.
egg yolk amber.

Maybe Barbra could try the rub test on the piece and see if there is any odor.
Thank you, JCD for your confidence in my nose...... cough cough.
Couple things could be done. I hope the guy who sent me the email is following the thread. Hot point, as mentioned earlier, would seperate from plastics or stone.
A good rub might generate some diagnostic piezoelectricity. Rub, rub rub with wool, silk or cotton and see if the unknown attracts small bits of ashes or paper cut into wee bits.

Piezoelectricity is the electric charge that accumulates in certain solid materials (such as crystals, certain ceramics, and biological matter such as bone, DNA and various proteins)in response to applied mechanical stress. The word piezoelectricity means electricity resulting from pressure and latent heat. It is derived from the Greek word πιέζειν; piezein, which means to squeeze or press, and ἤλεκτρον ēlektron, which means amber, an ancient source of electric charge. French physicists Jacques and Pierre Curie discovered piezoelectricity in 1880.
