India fluorescent minerals

      The specimens shown at right are from India.  The fluorescing red crystal specimens are ruby.  The matrix is zoisite    The red corundum will fluoresce under short wave ultraviolet light, but is more of a dull cherry red.  Due to the weakness of the fluorescence, we passed on the short wave image for web site purposes.
