Dugway geodes are from the famous old location out of Dugway, Utah. (Stock 664) Most have cavities lined with crystals, etc. (Please see photo image to the left, a double Dugway, rare.) Very few complete nodules are available. Depending on the total weight requested, naturally broken halves or partial geodes, which have a slight opening so that you can see a little into the geode will be sent. How do you break a geode without a diamond saw: draw a line around the center or tie a string around the center. Tap lightly, completely around the line on the geode several times with a hammer and chisel or until it breaks open. Even geodes as small as 1 1/2" thick may contain a beautiful surprise, so hammer with caution. For those of you that like fluorescent material these will be a nice addition. Price is $3.00 for one pound.
