Hi, all

If that serves for anything, I agree with Jordi and with Mr. Sampson-White (aka Rondinaire; in catalan. It means "grumbler" in English....). No offense intended, Is just as he signs....

Your piece has/shows conchoidal surfaces, the green is like green glass, the black is just suggesting that is anything thrown away. For rounding, even if found in a creek bed, one just needs to know how much time has it been there... Less time, less rounding.

With best wishes

Lluís

I do not consider the community of Hiddenite as western N.C. Hiddenite crystals are very distinctive, they are long and narrow, the faces have linear features characteristic of all spodumene. Your sample does not in any way resemble hiddenite. It is glass.

If you look at hiddenite from N. Carolina on Mindat you will see that the above statements are correct. While not sure it is glass [though it could be] it is surely NOT spodumene from N. Carolina. Do the hardness and S.G. tests. I can tell you REALLY want it to be hiddenite - but I think you will find it is not. It doesn't look at all like it and if it were, it is HUGE and unetched, as most were/are.

This thread is now into its second page.

The original poster put multiple posts with multiple photos onto the thread within the first couple of days on the website. Virtually all the expert responders have suggested that the examples are glass and not hiddenite. In addition the responders have suggested that some tests be done and the examples be shown, in person, to experts at a local university or museum.

For me the thread has outlived it usefulness and is growing a bit boring. I suggest the managers again suggest, to the original poster, taking the examples to university or museum for expert analysis and then close this thread. BOB
