I was surprised at how nice these rocks and crystals were. They are beautiful, polished and from around the world. You also get a lot of specimens! Fifteen in total. This kit was great for kids 5-13 years of age, however, the crystal growing part of this kit needs adult supervision and you can see that in a separate video.
Some of the samples were petrified wood, amethyst, quartz and tiger eye. Some of our favorites were green and yellow calcite from Mexico, the pyrite from Peru and quartz from Brazil. The obsidian is one to watch for because it can break to a sharp point. The selenite Rose from Mexico was outstanding and in both kits looked really good and measured about 3/4″. You can find this kit at Amazon and Rainbow Resource.
