Caledonite is a rare copper, lead sulfate and this classic, old-time specimen hails from the Type Locality - Leadhills, Scotland. Gemmy, turquoise-blue caledonite microcrystals are richly scattered in the two prominent vugs in the quartz-rich matrix. Adjacent to the caledonite crystals in the smaller vug are water-clear, tabular, microcrystals of the rarity leadhillite, for which this also is the aptly named Type Locality. Old material from the Archibald MacMartin and Princeton University Collections. Furthermore, this has a legit Princeton label, seldom released even in the few rare trades they have done.
