    this is old but I randomly ran across it. Throwing gemstones against a wall or trying to smash them is about the dumbest thing I've heard in ages. Diamonds and most of the other precious gems are incredibly hard, yeah, if you slowly push them against something... but they chip and even shatter with sharp force. If you happen to for some strange reason be holding a large, possibly real gemstone, don't shatter the thing. Find something porcelain that's not glazed. Maybe the bottom of a plate or vase, or the back of a tile. Push it against the porcelain and drag it. If it's not real, it will probably leave a streak of some kind. If it is real, it will scratch it if you applied enough pressure.

    actually the easiest way to tell if a 'gem' (they all have very different quality) is real...especially a diamond...is how it refracts light as carbon (a diamond) refracts light differently than glass(silicone/plastics, cubic circonium). Weight...nothing to do with it really. Give it diamonds are dense...glass is very very heavy. Also it is not a 'diamond' shape...diamonds look like crap before they are cut. There are many types of cut, which have 0 bearing on if the 'gem' is real. I could cut a rock into that shape...doesnt make it diamond shaped.

    That's a real gem, I don't know what this guy is talking about.
