Archaeologists made an intriguing find this week at Michigan’s Colonial Michilimackinac, Mackinac State Historic Parks officials said, an 18th century brass trade ring.

Researchers with the archaeological program at the Mackinaw City museum identified the piece as a trade good sometimes known as a “Jesuit Ring,” parks officials announced in a press release.

“It’s incredibly exciting,” Dominick Miller, chief of marketing for Mackinac State Historic Parks, told The Detroit News.
