Thank you Carles. BTW, the last four specimens in your collection thread (Vivianite, rhodochrosite, azurite, and vanadinite) are superb.

Mike,
Those are some very nice Elmwood specimens. I particularly like the Barium rich Celestine (2070 Celestite.jpg)…that isn’t something you often see from Elmwood Mine, TN, I can now see why the miners originally thought it was strontianite…they look awfully similar!

Thanks Jamison. You are right on about the celestite from Elmwood. I picked this one up in Tucson a couple of years ago, and it's the first one I have ever come across, despite the length of time that the mines have been producing. With the demand for the calcites, fluorites, barites, and sphalerites, maybe this species was not considered worthy of collecting.
Here a few more from Elmwood before moving on to another locality.

One of my favourite minerals is Calcite, so I love your Elmwood Calcite specimens. Really nice!

Thank you Don and Martin. Calcite's myriad of crystal forms and widespread occurrence make it easy to like and a wonderful mineral to specialize in.
I have chosen to show a few minerals from Pennsylvania in the next few posts.

Thanks Bob and Don. After re-reading the Min Rec article on the Wheatley mines, I can only imagine the many wonderful specimens that were sent to the crushers. In 1854, over 6 tons of pyromorphite was shipped to the smelter. The pyromorphite averaged 60% lead and contained 5 oz. of silver/ton.
Probably the finest collection of specimens from the Wheatley mines belonged to Charles Wheatley, the mine manager. His collection of over 6,000 specimens was purchased in 1858 and donated to Union College. Sadly, much of it was later stolen.

Thank you Pierre. I can certainly appreciate the intrinsic beauty of a mineral specimen, but having at least some knowledge about where it came from and how it formed makes it infinitely more interesting.

Hello Michael!
Congratulations to your excellent specimens and photos! I like this Cornish Cerussite and especially the Hematite from the Cavradi gorge. Theo Vencin is a well known collector/"Strahler" here in Europe.
