herkimer diamond with pyrite & dolomite , St. Johnsville Quarry
On one of my trips to Herkimer , New York , I met with
some of the local diggers and was able to purchase
some Herks that has dolomite  on the outside of the
crystal , as well as some pyrite that was both inside and
outside of the crystal.   These crystals came from the
Saint Johnsville  Quarry .
This site had unusual smoky crystals that the locals called ""Champagne Smokies"
