  Are manmade diamonds usually made from coal, charcoal, or atmospheric carbon? Because if it is either of the latter two, the resulting diamond will have a higher carbon-14 content than a mined diamond. That said, if you need a mass spectrometer to determine whether or not to buy jewelry, you're doing it wrong.

    Now there's an interesting thought... Atmospheric carbon. How many people would pay extra (over the cost of other man-made diamonds, but still less than artificially-inflated natural diamonds) for a product marketed as "carbon-sequestering anti-climate-change diamonds"? That's an emotional attachment which could offset the emotional preference for natural diamonds.

      You would need a lot of energy to separate the carbon from the co2. So your "green" idea actually makes things worse not better.
