A fabulous forest of isolated, spiky aragonite "trees" cover the "mesa" matrix on this striking cabinet specimen. This is one of the top examples of the aragonites from this one-time find of a couple of years ago - not only beautiful, but an important new find of aragonite from anywhere, much less America. They have a unique look, with tiny crystals growing like teeth on an earlier generation of sharp, larger crystals. This is not only a large specimen, but the crystals really stick up off the matrix in bold relief, in a series of interconnected bursts of crystals framed by the contrasting iron-rich matrix.
