How to determine if you have a genuine meteorite
1) Visual Inspection
If you've read the previous passages you now know much more about meteorites than the average person. Congratulations, and thank you for reading this far. Now, please carefully consider the following: Does your rock exhibit any of the characteristics discussed above? Does it feel heavier than it should? Does it have regmaglypts, or patina, or fusion crust? Compare your rock to the photographs of real meteorites, and meteor-wrongs.
2) The Magnet Test
Let me say it one more time. A meteorite will stick easily to a good magnet. If your rock does not adhere to a powerful magnet you almost certainly do not have a meteorite. It is extremely unlikely that you have found "one of those meteorites that doesn't stick to a magnet." Remember, there are many Earth rocks that also stick to magnets, so if your specimen adheres to a magnet it is not automatically a meteorite, but it's a step in the right direction.
3) The Streak Test
Iron oxides like hematite and magnetite are the Earth rocks most frequently mistaken for meteorites. They are moderately heavy (not nearly as heavy as iron meteorites) and appear metallic in composition. Some specimens will stick to a magnet. If you think you have an iron meteorite, here's an easy test you can perform at home: Take your rock sample and scrape it against the coarse (unglazed) face of a white bathroom tile, just like you were drawing on a blackboard with a piece of chalk. If your rock leaves a reddish or rust-colored streak on the tile it is likely hematite. If it leaves a dark gray streak it is likely magnetite. Iron meteorites will generally leave NO STREAK, or possibly a very faint grayish mark.
4) The Nickel Test
As discussed earlier, most meteorites contain nickel and iron. Naturally occurring Earth rocks do not, so if your specimen tests positive for nickel it may be a meteorite. Kits that test for nickel can be purchased via the internet, or you can take your rock to a lab that assays (tests) for various mineral components.

I would test the weight of with with a real balance scale. I wouldn't use any other type of scale.
On the other side of the balance scale, I would try gold, or iron, or granite. Or all three, to calculate the exact weight. You can then use the weight to find the "atomic weight". This would then give you a good idea of the density, when you compare it to size.
I would also test to see if there is any signs of burns. When entering the atmosphere obviously it will burn up a bit. Do you see any signs of a molten metal? Like drippy, wind/friction created blobs, or tear drops?
A lot of things in space are frozen, and ice, because of the vacuum of space. Do you notice any hollow areas that could seem to be where ice once existed yet melted away on entry of the atmosphere?
What is the weight at size measurements?
I was once in the desert and saw 4 civilian humvees driving around. They claimed to be meteorite hunters. They claimed they made their money by finding small meteorites, some of them the size of golf balls. They said some meteorites the size of golf balls can be worth up to $40,000.
So if someone says you don't have a meteorite, it might be because they don't want to fork over the cash that it is worth.

Also, all throughout the fusion crust are crevasses that reveal minerals, crystals (or diamonds, not sure).
