Hi Michael,

You are correct -- CVD diamond growth will typically use methane at a particular concentration for high quality diamond growth. If you google 'tequila diamonds,' it's true that they report diamond growth that could have been achieved using just ethanol and water, but apparently tried tequila just for its name over 'ethanol and water'.

Usually if you want to do this to produce high grade diamond, you would grow the diamond on an existing diamond substrate that serves as a seed. But if you read the (very lousy) paper,

http://www.ipme.ru/e-journals/RAMS/no_22109/morales.pdf

you can see they used silicon (?) and steel (???) as their substrates. In addition, the SEM images show that the diamonds grown are not in a nice block but instead a `clump' of little diamond spheres. They are likely polycrystalline, not single crystal, and there is no study of the actual diamond quality other than "we see a Raman peak that correspondes to diamond". Whopee.

Really shoddy research and there is no use for it -- the paper's primary conclusion is, "oh, tequila happens to have about the right concentration for making crappy diamond".
