Frequently Asked Questions

How do I know what type of crystal-growing kit to get for my child?

If you have a younger child who’s just starting on their crystal-growing journey, you may want to pick a kit that includes a starter crystal to help kickstart the process. Otherwise, it typically takes anywhere from one to two weeks for full-size crystals to form, which is fine for older kids but maybe not for younger kiddos with short attention spans. Look for a kit that also includes a comprehensive growing guide to make the process easier. Kits will have recommended age ranges, so it’s easy to find an appropriate option for most kids.

Are crystal-growing kits safe?

Yes, provided that you use them properly. Very young children shouldn’t use these kits, as the ingredients are toxic and could be harmful if swallowed. Be sure to check the manufacturer’s product specifications to choose an age-appropriate kit for your child.
