Make Diamonds from Carbon Dioxide in Your Breath?

What if you could make a diamond from thin air? Diamonds are made from carbon, so what if you used the carbon dioxide in the air, compressed it together, and made a diamond? How much air would you need? Could you even do it with your own breath, and make a completely unique, personal diamond for yourself or a loved one? This led to the back of the envelope question at dinner last night:

How many human breaths would it take to capture enough carbon dioxide to make an average-size diamond?


Answer: 20 breaths

36 mg of CO2 per exhaled breath (https://www.quora.com/What-is-the-mass-of-the-carbon-dioxide-exhaled-in-a-breath)

…which is 10 mg of Carbon (CO2 is 30% carbon by weight: https://math.wonderhowto.com/how-to/calculate-percent-composition-for-chemistry-301925/)

1 karat diamond is 200 mg of pure carbon (https://www.quora.com/What-is-the-chemical-formula-of-diamonds)

So, about 20 full breaths = 200 mg of Carbon = 1 diamond
