Bob Griffis' Photo Gallery

XN6-ARTFluorite, Baryte

Multiple photos available
Moffat Tunnel, Cripple Creek Mining District, Teller Co., Colorado, USA

Dimensions: 146 mm x 130 mm x 70 mm
Largest Crystal Size: 4 mm

Lustrous, gemmy, lilac-purple Fluorite cubes to 4 mm partly cover several intersecting sprays of flattened, elongated, tabular, white Barite epimorphs after Laumontite(?). The contrasting colors make for a very aesthetic specimen. The perceived color of these Fluorites varies depending on the color temperature of the lighting, and these photos are a bit more violet than they appear under daylight. They are not strongly fluorescent under UV lighting. This piece is very aesthetic, displays well from all sides, and is a top example of specimens from this limited discovery.

Rich Fetterd (Prospectors) specimen

X35-FYUMagnetite, Quartz (Var: Chalcedony)

Multiple photos available
Iron Springs Mining District, Iron Co., Utah, USA

Dimensions: 76 mm x 47 mm x 33 mm

This very unique specimen has metallic-dark-gray octahedrons of Magnetite coated with a thin layer of Quartz (var. Chalcedony) which act as the backdrop for rosettes to 10 mm of cream-colored Chalcedony. This is an exceptionally aesthetic specimen. It is free of damage, and out of several hundred of these I have never seen another like it.

6Q3-TP6Magnetite, Fluorapatite

Iron Springs Mining District, Iron Co., Utah, USA

Dimensions: 67 mm x 35 mm x 34 mm
Largest Crystal Size: 14 mm

A cluster of sharp, lustrous, metallic-dark-gray, intergrown octahedrons of Magnetite to 14 mm totally cover a matrix of solid Magnetite, accented with traces of lemon-yellow apatite. A lustrous, well-terminated, lemon-yellow crystal of Fluorapatite to 12 mm long is nestled near the center of the specimen. The luster of the Magnetite is brighter than typical for this locality. As the apatite forms first, and is later engulfed by the Magnetite, causing considerable stresses, finding intact Fluorapatites is not common. Except along the margins, this specimen is quite free of damage, and is an excellent example from this classic Utah locality.

GD2-5DYFluorite

Multiple photos available
Afton Canyon deposit, Afton Canyon, Afton, Cady Mts, San Bernardino Co., California, USA

Dimensions: 57 mm x 46 mm x 37 mm
Largest Crystal Size: 17 mm

A very unique, stalactitic knob of lustrous, translucent, medium-green, intergrown octahedrons of Fluorite to 17 mm. These Fluorites are preferentially coated on the front with thin-films of light-colored, fine-grained Fluorite, and on the reverse with a thicker coater of the same fine-grained Fluorite. California is not known for producing Fluorite, and there are only two localities that produce green (and octahedral!) Fluorites - this locality and the Felix prospect in Azusa; both of these localities are now closed to collecting. It is free of damage. Strongly fluorescent in LW, and less so in SW, which is uncommon.

R10-H3QFluorite

Multiple photos available
Afton Canyon deposit, Afton Canyon, Afton, Cady Mts, San Bernardino Co., California, USA

Dimensions: 70 mm x 54 mm x 30 mm
Largest Crystal Size: 17 mm

Lustrous, translucent, dark-green, intergrown octahedrons of Fluorite to 17 mm across, accented with cream-colored Quartz and coatings of fine-grain white secondary Fluorite. California is not known for producing Fluorite, and there are only two localities that produce green (and octahedral!) Fluorites - this locality and the Felix prospect in Azusa; both of these localities are now closed to collecting. Strongly fluorescent in LW, and less so in SW, which is uncommon.

1MX-UU3Fluorite

Multiple photos available
Afton Canyon deposit, Afton Canyon, Afton, Cady Mts, San Bernardino Co., California, USA

Dimensions: 44 mm x 43 mm x 11 mm
Largest Crystal Size: 7 mm

Lustrous, translucent, light-green, intergrown octahedrons of Fluorite to 7 mm. The Fluorite octahedrons are accented with cream-colored Quartz, and are free of damage. California is not known for producing Fluorite, and there are only two localities that produce green (and octahedral!) Fluorites - this locality and the Felix prospect in Azusa; both of these localities are now closed to collecting. Strongly fluorescent in LW, and less so in SW, which is uncommon.

RP8-0R7Beryl (Var: Morganite)

Cryo-Genie Mine, Warner Springs, Warner Springs Mining District, San Diego Co., California, USA

Dimensions: 150 mm x 118 mm x 113 mm

Beryl is 113 x 105 x 93 mm
Quartz is 136 x 66 x 55 mm

This is reportedly one of the largest (if not the largest) Morganites found in California. It was found in 2005 by Dana and Ken Gochenour, and bought the same year by Al Ordway. Al kept it in his collection until his death in 2007. I acquired it in 2016.

NWP-DPGPyrite

Mission complex, San Xavier, Pima Mining District, Sierrita Mts, Pima Co., Arizona, USA

Dimensions: 29 mm x 27 mm x 14 mm

A rare, brassy Pyrtite crystal from the Mission Mine complex in Arizona, it is tabular in form and a complete floater. The surfaces are covered with fine solution features. Formerly in the Bill Williams snd Fred Rhodes collections, it was collected by Fred Rhodes from the 2970 Bench in the late 1980s.

YJM-QE8Chrysocolla, Calcite

San Xavier pit, Mission complex, San Xavier, Pima Mining District, Sierrita Mts, Pima Co., Arizona, USA

Dimensions: 60 mm x 38 mm x 31 mm

Rich-blue Chrysocolla, mostly covered with sparkling microcrystals of clear Quartz, fills a vug in matrix. Whitish to clear rhombs of Calcite to 4 mm are perched on the Chrysocolla. This piece was collected by Fred Rhodes (a miner at the mine) from the South San Xavier Pit in the early 1990s, and was formerly in his collection.

San Xavier pit, Mission complex, San Xavier, Pima Mining District, Sierrita Mts, Pima Co., Arizona, USA

Dimensions: 48 mm x 41 mm x 38 mm

Botryoidal, bladed agregates of deep-green Malachite and lustrous, dark-blue crystals of Azurite, some partly altering to Malachite. This piece was collected by Fred Rhodes (a miner at the mine) from the San Xavier Extension North in the early 1990s, and was formerly in his collection.
