Yes, there is a slice missing. These nodules are the Great Pretenders, and you have to know what you are looking for. Our friends collected them. By the time we were able to go on trips with the rockhound group, the bed where these were was under a highway, or something similar.
Those are Soooooo cool!
ReplyDeleteOh, how incredibly cool!
ReplyDeleteThe knickname for these rocks is, "Thunder Egg", which is very appropriate. They are so heavy!
ReplyDeleteI still haven't found the big geode. It's as big a large grapefruit and very light in comparison to a thunder egg. I still think it was given to a friend to cut, and it's been forgotten.
Considering the difference in weight then, a thunder egg is solid but very colorful, etc. inside while the geode is one of those that is hollow and crystally inside? I love rocks. Every time we go backpacking, I leave the wilderness with as much weight in my backpack as when I began with all the rocks I collect. Once I carried out a serpentine boulder (I swear) because it looked pollished as was so beautiful. I just about did my knees in on that trip. They'll never be the same again! LOL!
ReplyDeletevery neat cut. love the name thunder egg :)
ReplyDeleteGeodes! They are a mystery to me. How they form, what magician put the right combo together..how do you know you have found one amongst all the other roundish rocks. I was reading an article about meteorites (and how space trash is often thought of as a meteorite) and one of the experts in the article talked about the beauty of a meteorite geode. I would love to see one of those!
ReplyDeleteThere was one for sale in St. Johns..a monster! Slightly less than a basketball. Amethyst. I could easily have bought that..but the pragmatic dh was with me. bummer
