I am selling this for a friend, and on behalf of the previous owner.  I was recently given documentation showing the owner was given access to dig at the Pennsboro Alley Agate factory, so this is likely from one of his digs there.  I will include a copy of the permission slip from the owners of that site back in 2013.  These colors most definitely fit into the Pennsboro color pallet.  This is a beautiful piece of cullet.  Runs from Red to yellow, and has the great lines across on all sides.  Beautiful from all angles.  There is a 'tad' bit of radium on the bottom, but nothing to get excited about.  Still, this needs a good normal light on it, not a blacklight to enjoy all it has to offer.  Buyer pays shipping, ships to US only.
