If the specimen is actually from Blackdene, I would be very surprised if there is any baryte present. The combination of baryte and fluorite is only seen in a few mines along the periphery of the fluo ...

A great specimen, Jesse. And a great story behind it :-)

Wish I knew more but I could not get anything from the dealer who had it back in Munich. I would be interested to hear from anyone who might ...

An old Weardale specimen, recently surfaced at the Tucson show. Thanks to New York dealer John Betts who once owned the specimen, I have traced it back to Henery D. Miller, a collector who was active ...

Yet another Beihilfe fluorite. I first came across this specimen at the Munich show a while back, 2011, I think. I wasn't quick enough and someone else got it first. I knew who the someone else was, s ...

Quartz (and sometimes other minerals) treated to an evaporated or diffused coating of titanium. Known commercially as "Aqua Aura", first appeared on the market in the mid 1990s as I recall.

I have a similar specimen, which was labeled "Val Cristallina, near Medel, Grisons, Switzerland". There is a Mindat page for the location:

In the back-lighted photo I see some black material in some of the corners. Possibly bitumen? This was common with fluorite from S. Illinois. Not sure about Wolsendorf or Frohnau.

Not England. S. Illinois is most likely, I think.

Another German fluorite. The first one I ever acquired around 20 years ago. At the time it was labeled "Weardale", maybe because of the Weardale-like twins, but I knew it was not. Barite and ...

Who is this person, and what happened to him? It looks like he was having fun, however!

I recall seeing a dealer at the Munich show around that time who was selling diamond in kimberlite matrix specimen that had been assembled, though without the statuary. They were, however, labeled &qu ...

Another Naica fluorite, which according to Pete's analysis would be cube-dodechahedral habit. From the find circa 2005.

Fluorite with dolomite and minor galena, from an unknown mine in the Wolsendorf area.

Pele's hair is a common byproduct of active lava fountaining during an eruption of basaltic lava at a volcano such as Hawaii's Kilauea. It is produced during fountaining when escaping volatile gases ( ...

It has been said that the only constant in life is change. After being involved with mineral collecting for around 40 years now, this is becoming all too evident. In recent years many of the dealers a ...
