This is an incredibly ornate, intricate crystallized copper that looks like nothing so much as an ancient ceremonial shield. It features SHARP (razorsharp!) spinel-twinned copper crystals radiating off to either side of a central atrray of two larger and more robust crystals running lengthwise down the piece. Between each spinel twin "spoke" are hundreds of tiny conenctor crystals in a herringbone-style pattern, reinforcing the strength and stability of the whole piece as well as making for a mesmerizing look. The piece is 3-dimensional, in that it has a thick midsection lending stability and support. This is a very UNUSUAL STYLE for a Michigan copper and quite different than most of what you could obtain from these old mines. I have seen no other quite like this for sale, except for superficially similar material from the Champion Mine - in person, though, they are quite distinct.Comes with custom lucite display base.
