Mineral ExchangesI want a Dundas, Ontario celestite with purple fluorite

4th Oct 2009 03:07 UTCAdam Kelly

I used to have one of these specimens years ago,

but gave it to one of my best friends.

I've just got to have one again.

The specimen I had, had a dusting of purple fluorite on one side, and a well shaped crystal.

I would be looking for a comprable piece.

I have many worldwide specimens for trade.

If you have one for trade, send me a wishlist, and I'll see what I can do.

Oops, sorry, that's not my specimen. I just found it in the db and thought I'd check. I may have something though, I'll take a look.

So you know Adam, Riener Mielke and Chris Stephano also replied to your request, but in another thread by accident. I'll let them know you're here.

Thanks Michael,

I would be thrilled if I ended up with a few pieces out of this.

I'm following the other thread also.

Hello Michael,

In talking to John Elliot last year about the purple stuff which is quite common at Dundas and he said the purple stuff was tested and it is a fluorine rich celestite not fluorite. Do you have an analysis showing it is fluorite?

Nope, and I'm totally inclined to defer to Tim. I never really knew what the purple stuff was, although I think I have heard fluorite before. The link I posted above is a John Betts specimen, I just knew that that was what Adam was looking for. It would seem to be a fairly common misconception though. Either way, it makes for really great looking specimens!

You've got some killers, BTW.

About a year ago I was questioned about this issue by a local Dundas collector. At the time, I recalled there was a study 15 years ago, but could not cite it. The collector was skeptical, but a month later he emailed me that he had indeed found a scientific paper that indicated fluorite inclusions in celestine -- not fluorine-rich celestine.

A quick internet search didn't turn up anything official, but Tim Jokela's ontariominerals.com does reference fluorite as "colorless, or minute purple granular inclusions in celestine and calcite." Maybe Tim can weigh in here. Tim? You listening?

Well I like them either way,

but would be interested to know.
