My first guess was a pseudomorph of ferberite or hubnerite after scheelite from Trumbull, CT. Ron Januzzi had a big collection of these at his old rock shop near Brewster, NY, back in the 1980s.

I'd like to pose the question: Is the "quest" for minerals (whether self-collected or purchased) more of a passion than actually getting more specimens? Do deer hunters find more pleasure ...

It looks like quartz, variety agate, to me.

If you determine where you want to go, make sure you ask the property owner permission to access his land. Trespassing while searching for minerals is what has closed a lot of localities for collect ...

The bonsai are magnificent. Did the labels give the information of how many years old they are? I know some of them can successfully grow for decades.

So far, there is no incidence, locally, of anyone with the COVID-19 virus in our area. We live in northern New York State, on the edge of the St. Lawrence river. Many cars with Ontario license plat ...

When donating minerals to a museum, there is usually a "deed of gift" form that is signed by both the curator or administrator in charge and the donor. This acknowledges the gift, but the m ...

The specimen of tremolite crystals does not look as though it had chromium in it, since the green is not the right color. The only places that have produced Cr-tremolite in St. Lawrence Co. are the ...

The new find of proustite crystals is truly noteworthy. I hope they are kept out of the strong lights as much as possible, since their red color will be affected over time, and they will eventually ...

Iron Out will remove a lot of the iron oxide stains, or you could use muriatic acid. If part of the matrix is marble/calcite, then the acid will attack it, resulting (maybe) in several smaller specim ...

Back in 1970, I took a geology field course in Maine. On the way home, Route 89 at Montpelier was just being constructed, and the road was dirt, and had some side lanes on it that didn't have any tr ...
