Here is an interesting one? It is a single crystal of analcime that looks a little different. I suspected that it may be partially pseudomorphed, so I had it analysed. In fact there is a lot of potassium in it, so I conclude that it is partially altered to leucite or some other K silicate? Mostly Sodium silicate, though. Was attached on back. Great crystal form!
