Seldom do you see old acanthites from this ancient district, isolated and on matrix. These relatively sharp crystals, to 1.2 cm in size, are really aesthetic, compared to most of the old acanthites we see from here. The matrix is 3-dimensional, and the piece is complete all around. It was in the noted collection of Arthur Montgomery, in the early 1900s. Recently, it was also in the noted classics collection of dealer/collector Larry Conklin. The crystals have a bright and natural patina and luster that is not the result of fancy chemistry to clean the piece, or whiten the siderite.Joe Budd Photos
