Vic:
Most of us who are not that familiar with the area can't help but wonder if this quartz is from the same general area that produces Herkimers. How about enlightening us? Wonderful quartz, by the way.

| Yes, John. I'm a little reticent about the exact location, but it was found not far from Margret Hastings fee site on Stone Arabia Road in Fonda, NY. The quartz bearing dolostone covers hundreds of square miles and this area is on the south east edge of it. The quartz found is varied and interesting ie. included, smoky, skeletal, perfect water clear double terminated, druzy and depending on where you dig, rather accessible. You mentioned in an earlier thread, if I got it right, that feldspars were under appreciated as specimens, I think Herks may fall into that category, especially ones with bits of matrix.

I haven't posted for a bit so I've got to relearn all this.
Including trying to get the best shot-which these are not.

Hi, Vic!
Many thanks for publishing your pictures at FMF again.
It would be better, however, to group several photos together in a single post. Just to prevent the system from sending so many email messages to the every subscriber.
Please, keep posting.

Usually, pink, red or lilac colors are attributed to cobalt but I believe that excepting some particular cases (like Bou Azzer or Congo calcites for example) the color is due either the atomic structure or the color centers.

Vic:
Does it fluoresce? If so, the chromophore may well be manganese. The only way to be sure, of course, is a chemical analysis, unfortunately.

There seems to be two generations of growth, the base growth glows orange and the overgrowth glows a faint pink under longwave.

Vic, what is its size? Approximately. I guess it's a quite heavy specimen, isn't it?
