Duftite on Quartz
Black Pine Mine, Flint Creek Valley, John Long Mts., Granit Co.
12.8 x 9.3 x 4.2 CM (cabinet)
A large plate of Quartz crystals up to 2 CM in size are thickly coated with Duftite in olive-green spheres. An old specimen from the Black Pine Mine that is famed for the great Veszelyite finds there. I have not seen another specimen quite like this from any USA locality it looks like a dark botryoidal Tsumeb Duftite on a Montana Quartz. An unidentified coating of brighter yellow is also present and adds some contrast. it is a very significant and sizable Duftite specimen with a lot of character. In good condition overall there are a few tiny chips on some Quartz but most are perfect and undamaged. The Black Pine mine has a complex and wonderful mineral assemblage including many uncommon associates. This piece is significant for the locale is the best USA Duftite I know of. Ex Chris Amo collection.
Duftite on Calcite
9.8 x 7 x 3.7 CM (cabinet)
new june 17
A striking cabinet sized plate of sharp Calcite crystals almost totally encrusted with bright sparkling Duftite micro crystals. In exceptional undamaged condition, Duftite is rare in good display quality specimens but this is a very fine and colorful piece. The individual crystals are more distinct and larger than the more typical Tsumeb smudges. Classic form for the underlying Calcite there is some selective coating noted but overall very little of the white calcite is exposed. Choice.
