AJ5-N84Epidote (CaCa)(AlAlFe3+)O[Si2O7][SiO4](OH) , Calcite CaCO3
Pampa Blanca District, Castrovirreyna Province, Huancavelica, PeruDimensions: 7.1 cm x 4.5 cm x 3 cm
A white Calcite matrix studded with solid green Epidote featuring a clean twinned Epidote crystal.
VU2-CMNGoethite α-Fe3+O(OH)
Pelican Point Quarry, Pelican Point Area, Lake Mountains Mining District, Utah County, Utah, USADimensions: 3.5 cm x 3.2 cm x 3 cm
Striations on the specimen give a good look into its past life as Pyrite cube. Which over time has altered into Goethite.
4DK-685Goethite α-Fe3+O(OH)
Pelican Point Quarry, Pelican Point Area, Lake Mountains Mining District, Utah County, Utah, USADimensions: 3 cm x 3 cm x 3 cm
Cube of Goethite after Pyrite with a growth contact step in the corner.
HL9-WRLGoethite α-Fe3+O(OH)
Pelican Point Quarry, Pelican Point Area, Lake Mountains Mining District, Utah County, Utah, USADimensions: 2.9 cm x 2.5 cm x 3.3 cm
Twinned Goethite after Pyrite single crystal. Specimen has signs of contact during its growth as the backside sits about a 45 degree which causes it to sit up perfectly and a indentation from another crystal on its side.

Poudrette quarry, Mont Saint-Hilaire, La Vallée-du-Richelieu RCM, Montérégie, Québec, CanadaDimensions: 6.2 cm x 4.5 cm x 3.5 cm
White Gonnardite coats a Rhodochrosite crystal on mineralized mass matrix.
2W6-L6QGonnardite (Na,Ca)2(Si,Al)5O10·3H2O , Rhodochrosite MnCO3
Poudrette quarry, Mont Saint-Hilaire, La Vallée-du-Richelieu RCM, Montérégie, Québec, CanadaDimensions: 8.2 cm x 4.5 cm x 3.0 cm
Bubbly mass of white Gonnardite on a Rhodochrosite crystal cluster.
CJ4-XWHSphalerite ZnS
Oronogo Circle Mine, Oronogo Field, Jasper County, Missouri, USADimensions: 7.5 cm x 5.1 cm x 4.6 cm
Large crystal of Sphalerite showing a few crystal faces within the host crystal. Self collected from the abandoned pit mines in Oronogo May of 2003.

Clean cluster of white Collinsite on a dark slate matrix
6F8-MF0Epidote (CaCa)(AlAlFe3+)O[Si2O7][SiO4](OH) , Calcite CaCO3
Pampa Blanca District, Castrovirreyna Province, Huancavelica, PeruDimensions: 4.8 cm x 3.1 cm x 2.2 cm
Twinned Epidote on top of solid terminated Calcite crystal.
G37-04RAndradite Ca3Fe3+2(SiO4)3
Pampa Blanca District, Castrovirreyna Province, Huancavelica, PeruDimensions: 3 cm x 2.2 cm x 1.8 cm
A nearly solid matrix of multi terminated Andradite crystals.
