Calcite orthorhombic dodecahedrons and octahedrons) crystal groups

dodecahedrons and octahedrons) crystal groups of Fluorite with a selective deposition of soft pink Rhodochrosite on one side of the piece

Here we have a very dramatic

Specimen# CO712B194

Our friend dubbed some of the colored material “blood vessel” Opal due to the interesting red/orange “capillary”-esque lines that can be seen in many of the specimens

The Brookites measure up to 7 mm long and are notably free-standing (not lying flat) on the matrix

Calcite orthorhombic dodecahedrons and octahedrons) crystal groupsUnlike some of the other major mines of the San Juan Triangle (e. g., Camp Bird or Idarado), Calcite is not terribly common from the Sunnyside Mine. This piece features dozens of sharp, translucent, white scalenohedra of Calcite which are gently dusted with sparkling golden Pyrite in select areas. Great condition overall, and certainly hard to find from this particular locality. The Sunnyside Mine was one of the most prolific localities in the history
