Ferrimolybdite : Fe₂[MoO₄]₃ · nH₂O
	Kingman District, Hualapai (Hualpai) Mts, Mohave Co., Arizona, USA 5.1 x 3.3 x 1.6 cm. A superb, unusually rich specimen of CRYSTALLIZED Ferrimolybdite from a classic locality, probably from the early 1900s. Usually one sees only a crust of microcrystals with no distinct form, but here we have true crystals. Rich on both sides of the specimen. Ex. American Museum of Natural History, with label.

Löllingite : FeAs₂
	Copper World Mine (Pacific Copper Mine), Yucca, Boriana Canyon, Boriana District, Hualapai (Hualpai) Mts, Mohave Co., Arizona, USA Lollingite crystal measuring 4mm in matrix with tremolite. As the specimens from this locality are mostly frozen in matrix, an exposed termination free of damage is quite rare. Michael Cline specimen and photograph.

Smithsonite : ZnCO₃, Calcite : CaCO₃
	Antler Mine (Antler Gold Mine; Spuyten Duyvel Mine), Arrastra Mt., Hualapai District, Hualapai (Hualpai) Mts, Mohave Co., Arizona, USA 6.8 x 6.5 x 2.6 cm. What you see here is solid smithsonite (rare in any form from Arizona, in fact, but particularly as manifested here). In the center, you can see the super-sharp rhombs which were originally calcite, but were entirely replaced by smithsonite, molecule by molecule, retaining the original form of the calcites. The reddish surface ...

Turquoise : Cu(Al,Fe³⁺)₆[(OH)₄\|(PO₄)₂]₂ · 4H₂O
	Kingman, Kingman District, Hualapai (Hualpai) Mts, Mohave Co., Arizona, USA 7.8 x 4.8 x 2.8 cm. Kingman turquoise is pretty much the "industry standard" for fine color. Here, a thin layer (polished) with sky blue color is set against the rhyolite matrix in which it formed. Ex. Dave Stoudt Collection.
