In this kit, they got to mine their own crystals. Since they are both big fans of the game Minecraft, this was very exciting for them. In fact when got up the next morning, they got dressed immediately and went right outside to the porch to continue mining.
In the end, they ended up with a total of nine crystals. It comes with a small pouch to carry them around and a card to help you identify the rocks.
They still continue to play with the crystals on a regular basis and it is pretty cute to hear my kindergartener talk about rose quartz.
