CBB86AQ0: Druse of flattened Barytocalcite crystals, a known but rare species, translucent, ivory colored, and on matrix.
The specimen comes from the collection of duplicates of Carles Curto (number 1978.105), whose label and computer file we will send to the buyer. Although it was stated to be Alstonite, we have analyzed it and the analytical results (of which we will send a copy to the buyer) show that it is actually Barytocalcite.
