Hi Shelley,

That is a nice piece! I should know what it is, but it won't come to me at the moment. The crystals look like they could be apohyllite; but it is difficult to tell. The one at the top looks like apophyllite as does the one in the middle. If they are, they should be square when looking down the long axis. And if there is one broken, it should show a cleavage plane that is across the crystal and also square.

These virtual identifications are frought with hazards. Did you try the Mineral Key that is on the Table of Contents page here at the Rock Shop? It might help.
