Jerrod Gallup (USA)
I got this selenite crystal at the first Pebble Pups meeting I attended. As a result, I researched this crystal and found lots of interesting facts, in particular, that it was very unique. This particular crystal was found in Oklahoma in 1970. In fact, you can go to Oklahoma and find selenite crystals on the salt plains there and the hourglass-shaped selenite crystals are only found at this location. It is also the Oklahoma State Crystal.
