Nice fluorite from Pakistan.
This is the first time I have seen fluorite crystals like these from Pakistan.

Hello Robert,

I have added the Poovey Garnet Mine to the database. The location of the mine is at Petche Gap which is just a short distance southeast of Morganton. Also, I changed the species of garnet to almandine, as that is the type of garnet that occurs there.

Your amethyst from Wilkes County, Georgia is probably from Jackson's Crossroads. I noted that you acquired a few of the specimens from Terry Ledford and Terry was one of the owners/operators of the amethyst mine at Jackson's Crossroads.

Regards,
Michael Shaw

Thanks. They were a pleasant surprise. With zeolite and tourmaline overload I had not been looking at many Pakistan and Indian dealers in Tucson. These I found after accidentally running into a 'pile' of mostly broken fluorite chunks in the corner of a primarily tourmaline / aquamarine / etc. dealer. I've started poking back into these corners again.

Yes. It was many years ago and all he would commit to at the time was a very vague location. I'm often torn between specifying as described vs. what additional analysis, including pictures, leads me to. For example, the answer occasionally to find something looking similar on Mindat and assume that is location is depressing. Thanks.

ROBERT, Are you sure your first 2 or 3 pix are fluorite? Smithsonite of these colors sure looks similar. And are you sure your last 2 pix are aragonite? They look like they could be calcite to me. For these examples, ID should be verified by more than just what some dealer said. BOB

Bob,
The Minggang, China location is noted for producing botryoidal purple fluorite - no smithsonite to my knowledge, despite the strong resemblance to specimens from Choix, Mexico.

I agree that the aragonite specimen looks more like calcite. Actually, it probably has some of both on it, as it likely came from one of the many cave locations in the area

Fluorite - Yes, I had some questions when first saw these. However, location and similarity to what's coming from Mingang were supportive. Also did some testing for physical/chemical properties. All were positive.

Aragonite specimen - Agree probably some of each. I have listed as Aragonite / Calcite in record. In the past when producing precipitated calcium carbonate products it was interesting to see how variations in chemical and physical operating conditions would impact crystal growth. Sometimes in undesired directions.

The days when had lab reporting to me and could have x-ray and other analytical info were great.

A bonus (?) and frustration collecting minerals from copper, lead, zinc orebodies is the diversity and the occasion of visual similarity. I have two specimens at home that look remarkable similar - they are pseudomorphs after calcite - both from San Antonio Mine, Santa Eulalia District, Chihuahua, Mexico. One is purportedly smithsonite and the other siderite. When time permits I need to conduct some tests to sort this out. Any thoughts?

Thanks,
Bob
