Excellent collection! Nov 15, 2008 I purchased this set for use in our homeschool studies of earth-science. It met and exceeded my expectations---the samples (9, no diamond hardness 10 is included) are substantial and lablelled, the storage box is sturdy and attractive. Also included are a piece of glass, tile, nail and penny for use in analyzing the hardness of various samples as well as a small instructional booklet. Excellent value, far beyond the schlocky sets I've seen locally in toy and educational stores.
