Yes - this is yet another "what is this".

I have received these answers so far:
Star Jasper
Massive Rutilated Quartz
Some ocean fossil coral replaced by something else. Pseduomorph of a Pseduomorph.

I am going to have to get help from Jordi to post photos

Sure Robin. Lots of guesses. But you can narrow the focus a bit if you provide a picture. I like the sound of massive rutilated quartz, particularly if the inclusions (if there are any) are sort of bronze/brassy-looking. But the picture will help. We're all waiting, and we look forward to helping you with your mineralogical curiousity.

All best wishes,

Ed

Here them are.

It looks as Pyrophyllite. If from USA, maybe from Graves Mountains.

Here's a picture of pyrophyllite from Bowling Mountain, Granville Co., North Carolina.

Awww!!! I missed out on the fun. Yep, pyrophyllite it is. Soft, isn't it?

Thanks so much - I looked it up!

PYROPHYLLITE GETS ITS NAME FROM THE GREEK WORDS FOR FIRE AND LEAF AS IN "FIRE-LEAF" AND IS NAMED AFTER THE GREEK WORD FOR "LEAF" AS WELL, IN ALLUSION TO ITS FLAKY FRACTURE AND APPEARANCE. BUT PYROPHYLLITE REALLY GETS ITS NAME FROM THE FACT THAT IT EXFOLIATES WHEN WATER IS DRIVEN OFF UPON HEATING LEAVING A FLAKY MASS.

Makes sense!

I wasn't aware of the North Carolina local! Thanks again everyone!

Well hello there Robyn!
How are you?
It really is a beautiful specimen you are holding, by the way!
If you want to add some of your pieces on the women's collecting section, let me know?
