Re: Need help identifying crystal chunk
I believe your specimen is probably from the Deccan Traps in India. View #1 posted to the photo gallery appears to show stilbite with apophyllite, the apophyllite being the greenish crystals.
I'm less sure about the bluish druze depicted in views #2 and #3. Cavansite might be a possibility.
