Top Crystals You Can Grow

Top Crystal Growing Projects 

Easy, Fast, Safe, Beautiful Crystals

Alum Crystals

Alum crystals are probably the most reliable crystals you can grow. You can get nice results overnight, plus you are using a cooking ingredient so you don't need to stress about safety.

Sugar Crystals or Rock Candy

The sugar crystals that make up rock candy aren't as quick or easy to grow as alum crystals, but they taste great and can be made in any color of the rainbow.

Borax Crystal Snowflake

Borax is used as a natural cleaner. The crystals will grow around overnight around any shape you can create, making this a quick and eye-catching project.

Copper Sulfate Crystals

These crystals are a vibrant blue color. They are easy to grow and among the most spectacular crystals to keep as display specimens.

Charcoal Crystal Garden

This is a classic crystal-growing project in which you mix salt and ammonia and laundry bluing on top of charcoal briquettes or a sponge.

Table Salt Crystals

Table salt or sodium chloride crystals are not the easiest crystals to grow, but the solution is non-toxic and everyone has the necessary ingredients!

Ammonium Phosphate Crystals

You probably don't have this chemical sitting around the house, but if you buy a crystal-growing kit, this is the compound that is used to grow the crystals. You can use these instructions to grow any color of ammonium phosphate crystal from scratch or you can use it as a guide to grow crystals if you lost the instructions to a kit, such as the Smithsonian crystal-growing kit.

Epsom Salt Crystals

Epsom salt crystals are clear crystals that are easy to grow. Another 'plus' is that it's easy to find Epsom salts in the pharmacy or laundry sections of most stores.

Benzoic Acid Snow Globe

This project is a little more advanced, but the results are worth it. You can cause non-toxic benzoic acid to form crystals in a water globe to make your very own customized snow globe.

Purple Chromium Alum Crystals

It's easy to make a clear crystal with a purple-colored crystal heart! Chromium alum crystals are easy-to-grow purple crystals. Once you have a purple crystal, simply drop your crystal into a saturated solution of ordinary kitchen alum to surround it with a clear exterior.

Glow in the Dark Geode

Do you want to make your own geode? There are several ways you can do this. One of the easiest is to use a clean eggshell as your crystal growing container. If you paint the surface of the shell with glow-in-the-dark paint first then you can create a glowing crystal geode.
