A magnificent large single crystal of selenite measuring in at 20 x 7 cm, and about 2.7 cm thick. It is in miraculously good shape for such a large, clean, exposed crystal! Common mineral, yes, but NOT in such quality and size and gemminess! This thing is so clean and clear you can read right through it, though it is an inch thick; and see right through it to the matrix underneath. This is a selenite of very high caliber worthy of any fine collection, and I do not say that phrase often!
