A very rare specimen of a type not often found here, featuring a stunning spray of lustrous, yellow-green crystals of unusual size. Marty had a half dozen or so of these, all of which I bought. This one features large, lustrous crystals to a whopping 4 cm-plus perched nicely on matrix, and complete all around. It is a dramatic display-quality miniature of great import for the species and locality. Marty's collection was world-famous for his suite of Mexican minerals but of those he was most proud of and dedicated to building the adamite suite. This is a significant pedigree for a Mexican adamite, but its a quality piece in and of itself, as well.
