I have a one of a kind Lake Erie Agatized Coral Fossil/Michigan Pudding Stone. Truly one of a kind out of any Agate. This is at the top best finds. Especially it being a pudding stone (conglomerate). For a regular agatized coral is one thing but add the conglomerate factor and all the crystals and quartz on it make it the number 1 for any collection of agates forsure.
