Peru fluorescent minerals

      The specimens shown at right are from the Winac Mine, Ancash Dept., Peru.  The specimens are manganocalcite on a matrix of quartz and rhodocrosite with a backing of pyrite crystals.   The manganocalcite is clear to opaque in normal lighting, the quartz is clear to milky white, the rhodocrosite is a light pink.    The manganocalcite specimens in  the middle column fluoresce pink when exposed to long wave ultraviolet light.  The photos at the far right show pink with a touch of orange fluorescence under short wave ultraviolet light.  Under both fluorescent lights the blue is the reflection of the lamp off the light colored rhodocrosite matrix.
