This large fan-spray of adamite is unusually robust in both size and weight, and is so much more solidly composed than most typical examples of this habit, a famous style from pockets of the 1960s-early 1980s. In fact, this is perhaps the single most robust example of the "pinwheel" habit we have seen, as the crystals merge together so tightly without the usual degrees of separation, into what looks like one common, composite crystal sharing a curving and broad termination. It is a cluster of many, but the terminations really have merged completely. It has a strong color, a unique uranium-like yellow-green that is hard to describe but is definitely more yellow than most adamite from here, and with less green component. It is impactful, impressive, colorful, and significant example. The piece dates to the 1970s or early 1980s by the old Ken Roberts label with it (Roberts Minerals, from his first wife Betty Roberts, judging by her characteristic beautiful handwriting). I have seen a thousand pinwheel adamites since the 1980s. This one is different in so many small degrees, it just stands out and this is so difficult to convey by photo alone. As a bonus, like all of these, it fluoresces neon green.
