Review: Happily surprised! - Way more rocks than I was expecting! Got these to stuff an advent calendar for my kids, and I was able to do about a dozen of each kind (except hematite) spread throughout the month AND have a ton leftover to give to a friend's kiddo! Only downside was 4 pieces of hematite in the entire box, but the rest had quite a few (see picture spread out on the included poster). Book is great; my kids loved reading about each kind, and liked the blank, lined page at the end to make scientific notes. There were no broken pieces or dust in the box, just a bunch of pretty gemstones! Highly recommend!
