| The fluorite and baryte from the Gaskins is exceptional. Neat old time specimen we normally don't see from the IL-KY Fluorspar District.

Thanks Jamison. As you know the vast majority of specimens available from the IL-KY Fluorspar district are from the Minerva, Annabel Lee, and Denton mines. I am always on the lookout for pieces from different locations. This year in Tucson, I found a combo specimen of fluorite/calcite from the North Green mine that I would like to have added to the collection, but the dealer was unwilling to negotiate, so I passed. If you are patient and willing to look carefully, these things show up every now and then.

Your pictures of the millerite in the Hall's Gap geode prompts me to add a bit to update the Hall's Gap locality.
As noted, the locality is on US Highway 27 in Lincoln County Kentucky, near the town of Hall's Gap. Millerite and its oxidation products were found there in small to medium size geodes about the mid 1960s. Immediately the locality became the premier geode road cut locality in all of Kentucky, becoming popular with Midwest geode collectors and it was very heavily collected. Over the next 20 years or so a dangerous overhang developed as the productive zone was worked back. The Kentucky highway department then posted the area, but some clandestine collecting continued. About 1980-1990 the highway department reconfigured the road cut, knocking it down and covering it up with ground cover so that today there is grass and bushes with no more exposed rock.
Occasionally I still get asked about collecting at that road cut, but it is and has been an extinct road cut locality for about 25 or more years. BOB

I would guess that nearly every collector has memories of specimens from a particular find that you failed to acquire when they were available. Every once in a while, however, a second opportunity comes along. The following piece is one such specimen. I remember seeing several flats of these Brazilian azurites in Luis Leite's room at the Denver Show back in the early 1990s. I didn't get one at the time and it must have been a limited find, because they disappeared quickly. I was very happy to find this one from an old collection.
