40+ years ago, a good lapidary friend of my dad's passed away and he was given by the widow this massive geode that looks sort of like a brain, but also is about the exact color and size of a largish canteloupe, along with some equipment and other things she didn't know what to do with. It weighs a ton. It was just boxed and mailed to me from Florida. My dad says his friend only bought the best material available (and it is from Brazil, as you would assume based upon the age and appearance). Based upon its weight, I am not too sure it has anything but solid rock inside it, though my dad seems convinced it does and is from an area that was yielding really great stuff at the time, including supposedly amethyst and citrine. My 10" saw is not going to make much headway on this 6.75" by 6.25" geode but I do have one lapidary friend who is quite inventive and will ask him if he can possibly devise a way to cut it open. Any thoughts on determining what might be inside? Any thoughts on cutting it open that don't involve taking it to another state and paying absurd sums? Or shoud I just hold onto it? The suspense may kill me.
