How long does it take for the crystals to grow?

Left undisturbed, you should see crystals begin to form within a day or two and full growth between 7-21 days depending on location and temperature.

are the chemicals used to grow these crystals toxic? Are the crystals safe to handle once they've grown?

Our Crystals can be handled once they are grown. We do recommend washing hands after contact. For more information please contact us directly at help@natgeotoys.com

Can you reuse the seed rocks to make new crystals?

If you have additional powder, you should be able to grow an additional crystal reusing the seed rock.

Can you touch the crystal

Yes, once your crystals have completed their growing process, let them dry thoroughly on a paper towel, and then they will be ready to handle. Although they are safe to handle, we do still recommend washing your hands after handling.
