Actually stilbite is not among my favourites, it's sometimes quite nice and often a beautiful addition in a paragenesis, but I rarely see a matrix specimen of only stilbite that really thrills me. This one does (though it may be common stuff from Maharashtra) - great colour and aesthetics, 10/10! :-)
Best regards

Thanks Tobi. Out of the hundreds of thousands of Indian zeolite that are produced it is pretty easy to overlook them. But a few really stand out and this one with the vivid orange color against the pure white background captured my attention as soon as I saw it.
Hope you and your family are well.
Regards,
Michael

10.0 x 9.0 x 3.7 cm | Though fluorite plays only a minor role on it - I like that one!

Thanks Tobi.
I would like to know more about this locality. From what I have seen, it produces fluorite in a variety of colors. Most of the pieces I have seen feature well-defined phantoms or at least strong color zoning.
