Hydrozincite, Calcite, Yellow ? under Shortwave UV - Columbia Mine, Marion County, KY

30.10.2016

The Columbia Mine in Kentucky can yield some really pretty specimens if you are persistent and crack enough rocks.  The rarest color is the red/pink calcite shown on this piece.  Every rock has hydrozincite, and many show the yellow we see here - not sure what that is - possibly fluorite.  2nd pic shows the piece under white light.
