Wonderful specimens as usual, Michael! I really love that beautiful purple fluorite cluster from Cave-In-Rock and also that perfect Elk Creek barite!
Best regards

Thanks Tobi. Both pieces are recent acquisitions. I think the barite is interesting because of all the facet-like modifications on the crystal faces and the fluorite is from a location in the southern Illinois fluorspar district that is seldom seen on the market.
It has been a challenging year for adding new specimens to our collection and I'm really looking forward to when we can attend shows as things start getting back to normal.
Michael

Michael, that is one of the most beautiful stilbite specimens I have ever seen! 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
Tobi

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
