geodes are awesome, there's no doubt about it. but why do you have to buy it, anyway?

so, i'm going to try to make a easy, cheap, and detailed geode at home.

Supplies

you will need:

a regular-sized rock

some tin foil

a glue gun

markers(purple & black)

Step 1: Gem Drawing

first, let's draw out a crooked circle/square for the gem. make sure the circle covers 20~50% of the stone.

now, let's place some tinfoil inside the circle/square. make it extra crooked and sharp, like a gemstone, but not too high-sticking.

not let's remove the tinfoil and color it purple. be sure to NOT change the shape of the tinfoil.

finally, let's glue the gem onto the rock. it one gem isn't enough, repeat 1~3 and make more smaller gems.

it's finished! looks pretty dope!
so there you have it: the world's most cheapest, easiest geode ever!
