This offer is for a mixed box of assorted mineral, fossil, and crystal specimens. Occasionally I received odd-sized lots of minerals, or small lots that are not suitable for stand-alone sale. I also have left-over pieces from cutting slices and redundant pieces in my personal collection. In this "mystery box" assortment, you will receive a mix of specimens that may include semi-precious stones, crystals, or fossils. The value of this box is guaranteed to be at least $40 worth of items if purchased separately.
