An incredible large specimen the size of a football, with dramatic, vertically-pointing azurite of the highest quality form and color surmounting the matrix of malachite-stained rock. The two largest vertical crystals are 2 inches, as seen from the back, and about 2/3 of that height is visible from the front view. The crystals have mirror-like lustre and sharpness as if they had been carved. All major crystals, about half a dozen, are terminated either fully or with minute contacts where they had adjoined matrix. One crystal is repaired, but so cleanly you could not tell unless you go looking for it. The overall aesthetic look of this is like a blue flower unfolding from the green host matrix, and it is one of the more dramatic larger specimens I have seen from Tsumeb. Exchanged from the Smithsonian Institution collection about a year ago, this piece was once obtained by purchase using the Roebling Fund endowment.
