Smithsonian Crystal Growing Science Kit

Real science, real results — the Smithsonian Crystal Growing Kit puts hands-on chemistry within reach of anyone curious enough to try it.

This STEM kit contains everything needed to grow three distinct crystal formations: emerald green, aquamarine blue, and golden citrine. Complete the chemistry portion of the experiment and you’ll begin observing crystallization within hours — then watch the structures develop and grow over the following days. It’s the kind of slow-burn science that rewards patience with something genuinely beautiful.

The included full-color STEM poster takes the learning further, covering the different types of crystals found in nature and their real-world applications in technology — from televisions and radios to computers. Science isn’t just something that happens in a lab; it’s in every device you use every day.

A perfect gift for curious kids and adults alike, and a great introduction to chemistry, geology, and the satisfying truth that the natural world doesn’t need any embellishment to be remarkable.
