If your kids are looking to get into chemistry or you just want to teach them about science, a crystal growing kit can be a fun first step. But with a huge variety available from a host of different brands, which is the best option?


There are plenty of kits to choose from ranging from the big names like National Geographic or the National History Museum through to more creative projects, allowing children to build crystal trees or sculpt them into rainbows and dolphins.

Below we've picked out the best crystal making kits currently available, offering something for all budgets, ages and interests.

The best crystal making kits

National Geographic purple crystal lab kit

Crystal growing lab kit from National Geographic

When it comes to crystal making kits, the brand that pops up the most is National Geographic. While it has a lot of different kits that you can invest in, the 'Purple Crystal Lab' seems like the best option, especially as a starter kit. You do only create one crystal but it comes with clear and precise instructions and the end result is a larger crystal than you'll get with some other kits.

The other bonus with this pack is that 27% of proceeds go towards the National Geographic Society, a nonprofit scientific educational organisation.
