Need help with initials/mark

[Greastart]

Found this on the floor of our business. Tried to locate owner for months. Nobody ever claimed it. Finally gave it to my wife

Anyone recognize the art/artist? One pic is a bit blurry. The blurred part reads 925. Looks like red coral? Found in Northern California if that helps.

Hard to tell on my phone. There is a PBJ listed under Danish makers. Though I haven't researched his style yet. Name is Preben Bengt Jensen 1961 and newer.
I doubt that's it though.

The stone is carnelian. It's a pretty popular stone. Sorry I can't help on the mark.

It almost looks Native American to me. I tried looking up those initials but couldn’t find anything. It could be a Native American piece but with an unknown makers mark.

Tried to take it to the jeweler today but they were slammed. Must be close to Valentine's day
