Since no one else jumped on this, here goes. Plume Agates come from all over and are distinguished from other agates by, you guessed it, plumes. I just got my new issue of Rock and Gem yesterday and the whole thing is dedicated to agates, what great timing. I remember someone else mentioning this issue at least a week ago, so i guess i got mine late. I always wonder how many people pass my mags around the post office before i get to look at them. My log home magazines were always very worn when they finally got to me. The rock ones seem to do better, guess postmen and women are not as interested in rocks. And since my expensive rock mags are also shrink wrapped, i don't have to worry about the postal people, just their machines that occasionally eat a magazine. Anyways, plume agates. I have recently read that there are at least 15 different types of agate inclusions and plume is just one. There are also moss, tube, dendritic, sagenitic, flame, etc. I am guessing that most plumes are jasper but there may also be some that are pyrite and other materials. So here's some pics. Please feel free to add pics and text and any other interesting and useful info. Also feel free to correct any mistakes i may have made. As for the names of the stones i am posting, these came from the dealers that sold them to me and may or may not be quite accurate. So please join in, we love pictures and info.
