A very dramatic piece, totally mesmerizing to me, with a medusa's crown of elongated SPINEL-TWINNED coppers leaping of a matrix of smaller crystals (all very sharp) ! This piece is 3-dimensional and looks good from ANY angle and any view. It is a mix of elegant atop a massive base, and the mix works. The piece is unique enough that, according to the Seaman Museum people who saw it, it is PROBABLY from this specific mine in the Keweenaw County heartland of copper mining. Comes with custom lucite display base.
