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

John White is is the former Curator-in-Charge of the U.S. National Mineral and Gem Collection, Smithsonian Institution, founder of the Mineralogical Record, author of two books and over 200 articles and hundreds of reviews and column contributions on mineral subjects and consulting editor of Rocks & Minerals magazine and the Russian journal Mineralogical Almanac. He is also a collector and a good friend.
