Priday Plume? I believe that to be a slab that I bought at the Lucky Strike mine. You may have bought it there, but it is not a lucky strike egg. One of the Richardson's beds would be my guess.

A life story. Birth and growth as a spheroid. Magma Cools, Pressure releases and water slowly "flashes" into steam producing the Star Chamber.Centuries pass. A heavy rainstorm! Water passes through limestone and Ph increases to the level it can dissolve chalcedony, moganite, and tiny spheroids. All rush along into cracks, crevices, fissures, into the Star Chamber and beyond. Ph drops in the chamber and SiO2 needles of chalcedony and moganite alternately adhere to the chamber walls, spheroids float in the voids. Metals grow into ferns and plumes. The flood continues to pour through, then finally stop and all dries up. More floods with different minerals follow. A short storm, the chamber only partly fills, settles into flat layers. Another heavy storm fills the whole area.

Beautiful. I can get lost wandering through each and every one of them. Look like alien landscapes. RocksInNJ might get homesick looking at these. Indeed, but at least I have some Earthen BBQ to feast on in the meantime.
