Smithsonian National Museum of Natural History: Part 5 - Oxides, Sulfides, & Halides

When we made our visit to the Smithsonian gem and mineral hall, we took hundreds of photos. After going through all of them, there are over 60 we felt worthwhile to post. Instead of making one long post with all of them, we divided then into several posts of related items. We had to think of a common grouping method, so we chose to separate the posts by mineral type classification. This post shows some of the oxides, sulfides, and halides in the Smithsonian collection.
