Villiaumite from Mont St-Hilaire
VAL6-1 Valleriite $75 SOLD
Copper Belt, Whitehorse Mining District
3.2 cm x 2.6 cm x 2.6 cm
Patches of bronze-colored Valleriite (Fe2+,Cu)4(Mg,Al)3[(OH,O)6|S4], a rare sulfosalt, richly infuse this specimen. Since Joe Cilen had a collection numbering in the tens of thousands, I guess this one (#6292) was an early acquisition. The specimen comes with his label.
Vesuvianite $65 SOLD
More than a dozen Vesuvianites (Ca10(Mg,Fe)2Al4Si9O34(OH)4) up to 1.2 cm on edge are strewn about the matrix. Matrix specimens from Lake Jaco are hard to find, and this one has good coverage of lustrous Vesuvianites.

La Verde Mine, Copiapó Province, Atacama Region, Chile
3.2 cm x 2.8 cm x 2.4 cm; largest Volborthites ~ 2-3 mm
