And, as fairly frequently at the Denver Show, Denver resident Ralph Clark put in a case of selections from his fabulous thumbnail collection--with the Montana veszelyite, Tsumeb mimetite, Chilean proustite, Swiss anatase, etc.
And I and my fellow thumbnail collectors are always delighted when Ralph Clark puts in a case of his best; at this show we saw 30 of Ralph's most incredibly fine thumbnails, and maybe if I mention particularly his Swiss anatase, Montana veszelyite, Australian chalcocite, Chilean proustite and South African rhodochrosite, he will someday trade me one of them for my very best Herkimer diamond .
Allan Young put in a dazzling competitive case of thumbnails, and for his trouble he won a "Trifecta," taking not only the Master award for competitive cases but also the Desautels award for best case in the show and the Lidstrom Trophy for best single specimen (his veszelyite from the Black Pine mine, Montana).
An extraordinary find of the rare mineral veszelyite from the Black Pine mine, Philipsburg, Montana was exciting to see.
It was also among the first known occurrences of veszelyite.
Chrysocolla has been reported with veszelyite (Buttgenbach, 1947).
He found something blue, and was doubly successful because some crusts of microcrystalline veszelyite were indeed pan of the assemblage recovered (personal communication of Dr.
Judging from the original description and from observations of later-recovered specimens, the associations include pseudomalachite (as blue or green nodules), some malachite, hemimorphite, white prisms of pyromorphite, ultramarine-blue microcrystalline masses of veszelyite, yellow and olive-green crusts of vauquelinite, libethenite (as acicular clusters, as small nodules with a radiating internal structure and also as equant to short prismatic crystals to 3 mm isolated on matrix), green pseudomorphs of reichenbachite after kipushite, quartz, and iron oxides.
As with veszelyite, the Cu:Zn ratio is variable due to a complex structure composed of alternating sheets which are different in each species (Piret et al.
Much less abundant was the well-crystallized ultramarine-blue zinc-copper phosphate which was not positively identified as veszelyite.
The author considered that it could be veszelyite, yet the crystal habit was quite particular, with a large (typical) "orthopinacoid" {100} which had not been observed in the original veszelyite.
Allan's Chilean proustite, Tsumeb dioptase, Tur kish kammererite, Mexican acanthite, Congo cuprite; Ralph's Swiss anatase, Brazilian autunite, North Carolina hiddenite; both men's Montana veszelyites .
