    So they say you can tell if a diamond is real because a real diamond will remain cold whereas glass will become warm (if you lick it).
    What I don't get is why glass would be warm when it's supposed to be a poor conductor and the diamonds would stay cold when they're supposed to be good conductors?
    Pretty random question I know!

    Sounds like ******** to me. A better test would be to scratch both with sand, if there's a mark it's glass.

    well as a jewelley dealer, diamonds are something i see everyday but the method for testing successfully other than a diamond tester is
    the breath test in which you breath on a stone and a diamond will quickly demist unlike anything synthetic which remains foggy for little while

    "Synthetic" is an extremely poor word to use in that context on a chemistry forum.

    i use the term we use in the trade be it an actual simulated stone or glass or plastic or even moissanite or quartz they're all not diamonds but the last two have some value and other are just going in the bin
