✅ SOLVED Possible Pirate Era Ring?

[bonepicker]

A friend showed me this and asked if I could get any info on it.
They said they purchased it at an antique show and the seller said it was a pirate ring.
The brass ring does appear to look aged, and looks similar to what some of the early 17th-18th century trade rings that I have seen, but the design is throwing me off.
The square logo with the cutouts does not look like anything I have ever seen.
Anyone ever seen anything like this. What is it? If its a ring, it seems strange the design is offset instead of being in the center. Any ideas.
Thanks for looking.

"Seller said it was..." are four words that should send up red flags to every collector.

Mayan or Incan ?

True story:
I had a friend once who was a happy, if compulsive "garage sale liar".
I remember he tried to get rid of an UGLY set of (very used) golf clubs by claiming they once belonged to Jackie Onassis!

Buyer beware, indeed!!
