Obviously, this falls a bit short of what we think of when we hear "diamond". But, after posting the original article, I came up with a pretty cool way to preserve my achievement.

I filled a small washer with clear epoxy and dropped my diamond into it. After it hardened, I strung it on a chain to make a diamond necklace.

My wife was impressed. After all, how many women can wear a diamond that their husband actually MADE?

get a file and try to file it. If the file grooves thin out then, voilà you have made the worlds hardest material. And it also files away any other graphite debris

You do realize that this ible was meant to prank the instructables community right?

This is by far my favorite article I have read on this site. At the same time it only diminishes my faith in humanity. I truly applaud your wit and creativity.

Dude you are so cool!!! I love this article and I will tell all my friends about it!!

i know this was a while ago but i have to say it cause no one else did. GULLIBLE!! lol microwaves have a built in safety switch, if you pulled the microwave apart (don't do it if you ever want to have kids) it would be possible to make a diamond, but you still need pressure. :)

Pressure may not need muscle from 'comprehendable' sources..just a little freezing of water in a glass bottle sealed shut will pop it..who knows if there is another unknown discovery about pressure going on withing the combination of componants in the microwave alone?..Maybe being enclosed isn't exclusive..they weather is an open-air pressure story..

I used a recipe 5 or 6 years ago using charcoal brickettes and oil in the microwave and it did produce a pile a sharp little brutal chystals..I never had them checked though. But they were black and somehow I hoped they're be clear..
I did fry my old micro, but I never used it on food anyway..

wat's really funny is it is theoretically possible haha but you would need more than 5GPa At 1500 degrees C. or win the heart of a technician who makes them CVD style, and get them to tell you. ;)

I think you would be better off and SAFER (well maybe not safer) using a Thermite reaction to generate the heat (5000 degrees).  You can make the fake diamonds faster and in bigger quantities.  Use clay pots that are used for plants as your crucibles.  For the pressure, put it all in a scuba tank and pressure it up (3000 psi).  If that doesn't make diamonds better than nature, nothing will! 

PS -  the patent is pending!

Won't the thermite destroy the tank and have a blast of air from the scuba tank?

Na na, you've got it all wrong. Juggling chainsaws is step 3, step 2 is the hospital. Mind you step 1 is time travel amoung other april fools day worthy articles.

I know that this was a fake 'ible, but there is real promise in the idea of using a microwave magnetron to create a synthetic diamond. You would need to do some serious altering, make a thick lead box, mount a stainless carbon steel vice in this new lead box, increase the power output of the magnetron to about 3kw.

When something like this is running, the focused microwave radiation will create temps around 4000f degrees thanks to the heat retention abilities of the steel vice pressing on the carbon ingot. Let this run for ten days straight and shut the unit down. Wait about five hours for the unit to completely cool off, then check the end product.

*Patent pending on the unit, btw*

This is cool and all but does it really work I men pencil lead and oil come on

Why not use black mugs? Wouldn't they get hot faster?
Apr 10, 2009. 12:24 PMXkidXhavocX says:
black only gets hotter than white under light..
Apr 23, 2009. 8:16 PMSKULLOK says:
microwaves are a type of light that is beyond recognition of human ocular receptors. However, you are partially correct in that using black mugs shouldn't really do anything different, as black doesn't mean that something is more conductive to heat, but rather that it absorbs more colors of light, which when dealing with microwaves, color doesn't really come up. Water, fats, and sugars, on the other hand, do. This is probably why the oil is needed, more than anything else, as pure graphite would not heat whatsoever in a microwave oven on its own (and with minor impurities and other various particles from your skin or the air, it might heat up, but not nearly hot enough for something like this). However, with the crucible, though I'm not sure porcelain or ceramic mugs would really do the trick here... I'd have to see it myself to believe it (sparks in a microwave usually means "METAL!!!" and considering this is carbon... and it's supposed to be in a crucible... again, I'd have to see this to believe it.

Hm. Well we know this is an april fool joke but graphite is electroconductive so it's feasible that the graphite itself would also spark under microwave

soo many ppl think this works... i lold hard

Awesome instructable! Seriously. That's amazing. A few questions/thoughts: 1. Why extra virgin olive oil? Was this just what you had available or is there something preferable about it? 2. Would a bigger piece of graphite yield a better/larger result? I know they make very thick pencil lead for certain drafting pencils. Maybe powdered graphite would work (with a dollop of oil, naturally)? 3. Any idea how to remove the scale? maybe a rock tumbler with incredibly fine grit? Again, awesome job. I can't believe how simple and ingenious this process is. I can't wait to try this out.

Wow...... really? But... I already took out a second mortgage to start my microwave-oven synthetic diamond business.... smallbusinessfail.

if u make the oil go onto more of the thred would it make the fake dimond bigger? that was coool
