Notes: I got this selenite crystal at the first Pebble Pups meeting I attended. I belong to the Lake George Gem and Mineral Club.  I researched this crystal and found lots of interesting facts. I found out that it was very unique.  This crystal was found in Oklahoma in 1970.  You can go to Oklahoma and find selenite crystals in the salt plains there.  The hourglass shaped Selenite crystals are only found on these plains. It is also the Oklahoma State Crystal.
