I’ve posted the second in a series of updates with superb specimens from John S. White’s collection (click here).

Most of you will likely know a bit about John, given that among his many accomplishments in the mineral world he is the founder of the Mineralogical Record, former curator of the U.S. National Mineral and Gem Collection at the Smithsonian Institution and author of two books and over 200 articles. I’ve written a short post about him with some great photos – hope you enjoy it! (click here)
