Hallmark JMc?

I have a pendant with the hallmark JMc (the c is underlined.) I generally buy pieces directly from the artist, but this one I did not. Would love to find out who the craftsperson is. Thanks!

Here are pics. I purchased the piece at Soaring Eagle Casino and Resort in Mount Pleasant Michigan. They claim all their pieces are authentic, but could not provide me with info on the artist. The wholesale buyer for the resort states most of the pieces come from the southwest states.

Not familiar with the hallmark, sorry.

Thanks for checking, Jason.
