I bought a pair of 7mm diamonds that are said to be made with chemical vapor deposition. They're very nice and very cheap, at least relative to the mined diamonds. If anything, they're too perfect. The natural ones are imperfect in the way that real wood siding is less perfect than vinyl siding on a house.

Imperfect how? My understanding is that unless they're coloured, cut diamonds are perfect and uniform down to the atomic level.
