TR pendant

[collector19]

Hello!
A friend of mine has this (what I believe) pendant. He now wants to know, what this thing is and if it´s authentic!?
I believe, it´s not authentic and therefore a junk. But maybe you guys can help us out?
Has anyone of you ever seen such a thing?
The thing is stamped with an "800" on the ring!

Best Regards

I can just share the link to another forum, where I have posted the pendant...
Sorry for the inconvenience
