You are buying the nodules in these pictures. From Beacon in western Idaho. These are ready to polish or display as they are. There is four pounds of halves from 1 to 3 inches. The crystals in the geodes are beautiful. Some are full of quartz crystals, others have agate and jasper. All will take a superb polish. I toss out the few duds I do find and you get the best pieces. There is a lot of cutting time but I will start the auction at only 10 dollars. Does not even cover the gas. The digging is free because I love it.
