JC12694.  Ludlamite.  Cabeça do Cachorro claim, São Gabriel da Cachoeira, Amazonas, Brazil.    11.4 x 8.8 x 2.2 cm 375g   $450.00   First saw these 3 years ago at Tucson.  Since then there has been a lot of material available, and has so often happened with mineral finds, they will quickly disappear from the market place.   Beautiful green glassy lustrous translucent crystals of ludlamite measuring to 1.0 cm in size mostly covering the top of this matrix.  Fine example for the species.

Big Windy Peak, Lemhi county, Idaho.  7 x 8.5 cm  221g.  $125.00.   One of the few matrix pieces.  This one was in a narrow vein, so the crystals sticking vertically up from the matrix contacted the opposite wall, which left a beige residue on there ends.   The beige material is supposedly forsterite, but I have not had it verified.

JC11368.   Mimetite.  Velardeña, Velardeña District, Cuencamé Municipality, Durango, Mexico.  9 x 11.5 cm   362g.  $250.00.   Olive-green spherical clusters of nubby to euhedral mimetite crystals totally cover the undulating surface of this  large plate from this much less well-known extensive mining district in Durango.   Mineral specimens are in fact, rare from Velardena.  Cuprian green mimetite is a rare varietal from this locality, as mimetites shown in mindat are yellow. The bit of scattered bruising is certainly only a modest detraction to this rare, very rich, and showy large piece. Ex Bob Reynolds Collection
