In a recent episode one of the characters breathes on a stone
and claims to be able to tell whether it's a diamond or not by observing the rate of evaporation. |

Yes, and then he can change inside a phone booth and fly away :-) All jokes aside, maybe there is such or similar "method of identification", but today we have synthetic diamonds which surely can't be so easily detected. |

Whether there's an actually useful form of identification is debateable. But diamond IS very different from the simulants in it's very high thermal conductivity, which would affect condensation and evaporation if, for example, the stone were quite cold, or the like... But for the rest of use not on the CSI show, it's probably more reliable (and easier) to just look at the stone carefully with a good loupe. You seldom need more, at least to determine the simulants. True synthetics are going to be much more of a problem when they become more widely available. Peter |
