HOP8-1  Hopeite  $275  SOLD

Kabwe (Broken Hill) Mine, Kabwe, Central Province, Zambia
ex. Wein collection #7079 (number tag on specimen)

9.3 cm x 8 cm x 5 cm

Centuries of bat droppings are said to aide the crystallization of Hopeite in the caves at this locale by providing a rich supply of nitrates.  This specimen contains over one hundred relatively large (up to 6 mm) prismatic Hopeite crystals on a heavy matrix, probably Smithsonite.  Hopeite (Zn₃(PO₄)₂•4H₂O) is a quite rare hydrated zinc phosphate found bigger than micromounts at only a few locations worldwide.  The biggest and best Hopeites are said to come from this mine, and this is a very rich specimen.

GEO10-31  Howlite Nodule "Poodles", pair mounted in plaster  $45
ex collection of C. Gustafson of Inglewood
ex Linda St-Cyr collection  SOLD

Tick Canyon, Lang, Los Angeles Co., California

11.5 cm x 5.7 cm x 2.9 cm = dimensions of the mounted pair

Tick Canyon is famous for its Howlite (Ca₂B₅SiO₉(OH)₅) nodules, and this nodule looks exactly like the faces of two dogs!  I can see their ears, eyes and noses.  Howlite is sometimes dyed blue as a fake Turquoise - its texture and the black lines running through it do make it resemble Turquoise, but usually the dyes are too bright to be real Turquoise.
