Agate Slice

2 total reviews

    Item #119


    Agates are rocks consisting of microcrystalline quartz called chalcedony. They are typically formed in pockets within cooled lava. As water flows through the lava, the pores in the cavities - called vesicles - act as tiny filters which catch silica particles that were in the water. As these particles accumulate, various silica based minerals can be deposited to create colorful bands in the rock which can be seen whenever the rock is cut open.

      Super fun

      I love that every item comes with the information cards explaining a bit of its history/qualities. Fun gift for my scientifically-inclined partner.

      WE TAKE SCIENCE SERIOUSLY

      You deserve better than craft store science products. And we think learning is more impactful when you're holding a tangible piece of what you're learning about. That's why Stemcell exists.

      We're dedicated to providing the best scientific products available—whether they're fragments of scientific importance, experimental activities, or just interesting things that scratch your curiosity itch.

      With every new product launch, our list of new ideas gets longer rather than shorter. So check in often for our latest projects, and thanks for being a part of our endeavor to make the world a smarter place to live.

      Believe in yourself; for everything else, there's science.
