I was recently asked about quartz collecting in PA.
I have not actually collected at Crystal Point Diamond Mine in Williamsport PA.  Several years ago, I was in Williamsport on business but did not have a chance to visit the mine.

There are plenty of reference to the  Crystal Point Diamond Mine.
The http://www.raytowneinc.com/CrystalPointDiamondMines.htm link is broken probably because the content is no longer on   http://www.raytowneinc.com.
If someone has visited the mine recently, please post a comment or email and tell me when you were last there and how was the collecting experience.

  Thanks Gary K.
