Yes one of them is prehnite. Some of the more browny-green ones seem to be this too. I'm not sure what the other yellow one is but I've removed it from this group.
And yes both the blue/white and the purple/white are sodalite I just checked you can get purple Sodalite)Christine gets an A which is upgraded to an A+ because of how blurry the pics were (my mobile is being difficult at the moment)Thanks Oh and I think the black ones are black onyx??
Just discovered the other yellow stone that wasn't prehnite it's lemon yellow magnesite I might keep that one lol
Ah, it's a gift! pmsl.....youknow how I feel about being right.
Cool, I haven't worked with that one.
