You generally see these so-called "Herkimer Diamonds" (quartz) alone or in groups, apart from the matrix. But this very large specimen is really interesting in that you get to see them in their natural setting. They are found in large hard-rock boulders that must be split apart (the labor is supposedly quite intense to find these) in order to search for and expose the little pockets in which they have formed. They look like diamonds glittering almost impossibly inside the gray, dull host rock - as if they were place there. There are two separate pockets on this one specimen, with crystals up to 1.5 cm.
