Sharp crystals to 1 cm, showing unusual 3-dimensional form and quality, for this rare mineral species.
3.6 x 2.3 x 1.8 cm. Hopeite is a RARE hydrated zinc phosphate, with the very best specimens worldwide coming from the famous Broken Hill Mine of Zambia. This extremely rich miniature from the Carl Davis Collection has gemmy and lustrous, orange-brown prisms to 5 mm.
5.7 x 3.6 x 2.7 cm. Hopeite and parahopeite are RARE hydrated zinc phosphates, with the very best specimens worldwide coming from the famous Broken Hill Mine of Zambia. This EXTREMELY RICH and showy honeycomb specimen from the Brent Lockhart Collection has gemmy and lustrous, orange-brown hopeite prisms to 3 mm on a nearly solid matrix of glassy, pastel yellow-green parahopeite crystals. Broken Hill is the Type Locality for parahopeite. We lovingly call them bat-poop minerals because their crystallization is spurred by the rich nitrates from centuries, or millenia, of bat droppings in the caverns here (so I have been told long ago!). Uncommonly pretty combo material for these two dimorph species, which probably dates to the 1950-60s.
3.5 x 3 x 2 cm. This pseudomorph of hopeite after hemimorphite is spectacular and it is very rare. Diverging blades clearly exhibiting parallel growth of hemimorphite, to 2.5 cm in length and of an umber color have been replaced by hopeite, the much rarer zinc phosphate. Ex. Martin Zinn Collection. This Photo was Mindat.org Photo of the Day - 1st Sep 2008
4.1 x 4.0 x 2.3 cm. Hopeite is a rare hydrated zinc phosphate, with the very best specimens worldwide coming from the Broken Hill Mine of Zambia. This superb honeycomb specimen is a nearly solid mass of gemmy and lustrous, orange-brown hopeite prisms to 9 mm on just a thin crust of matrix. These are large crystals for the species. Super and very well crystallized material, which probably dates to the 1950-60s. Accompanied by a faded Burminco label.
Lustrous, transparent to translucent, colorless hopeite blades to 8 mm aesthetically set in a powder-blue, botryoidal smithsonite vug in matrix from the famous Broken Hill Mine in Zambia. Hopeite is a very uncommon zinc phosphate and this is a good one. Ex. Lewadny Collection 4.0 x 3.1 x 2.5 cm
Rare, sharp euhedral crystals of hopeite perched in the most unlikely place - inside a vug of blue smithsonite! This is very rare from Broken Hill, especially in this quality, and without the hopeite association I would have doubted it thoroughly! This was surely mined prior to the 1960s when the locale was at its peak. 4.3 x 3.5 x 3 cm

With out question this pseudomorph of hopeite after hemimorphite is not only spectacular, it is very rare. Diverging blades clearly exhibiting parallel growth of hemimorphite, to 2.5 cm in length and of an umber color have been replaced by hopeite, the much rarer zinc phosphate. Awesome!
