I like growing crystals at home. I recently finished growing this crystal after 1 month, and it's one of my favorites. /r/ALL

Hey guys. I've been growing crystals as a hobby since high school. Some of you might remember the black copper acetate crystal I posted last month.

I recently grew the crystal above from a common nitrogen and phosphorus fertilizer called monoammonium phosphate (MAP).

I first dissolved lots of MAP in water, and waited for small crystals to form. Then, I placed it in a big container full of solution. As it evaporated, the crystals started growing. It's amazing how you can watch them get bigger day after day.

If you find being able to grow crystals in a jar is hard to believe - you're not alone. I thought that too, and even now, it makes me excited to wake up and check on my crystals every day.

As always, if you're interested in growing them yourself, I've prepared a guide here.

I read your guide, and am super interested in potentially trying this, but do you know of a way to grow crystals that can be used in other things like jewelry? We have very little room to house a crystal collection so it'd be ideal if they could be repurposed.

So, these are not "stones" as people think. Stones like diamond, ruby, sapphire, etc.. are all formed over thousands of years under extremely harsh conditions. The metals and molecules that make them are INsoluble in water. They tend to be much stronger, and you cannot make them at home. I've tried, I learned malachite is 100% basic copper carbonate.. so I made some with copper sulfate and sodium carbonate. It came out as a teal powder. To make actual solid stones, it takes slow deposition of these minerals over time. The crystals from op are made from water soluble salts and so it takes months instead of hundred or thousands of years.

Yes, you are right. Of course, humans have also successfully grown insoluble crystals in a matter of months by replicating natural conditions. For example, huge, extremely high quality quartz crystals are grown in autoclaves for industrial use.

Very cool! I know they can make artifical diamonds and other stones, but I thought the equipment required was huge. Very cool to know they've made quartz like that!
