How do I know if my rock is worth money?

The harder a mineral is, the more likely it is to be valuable. If you can scratch the mineral with your fingernail, it has a hardness of 2.5 Mohs, which is very soft. If you can scratch it with a penny, its hardness is 3 Mohs, and if it takes a piece of glass to scratch it, the hardness is 5.5 Mohs.

Finally, compare the properties of your rock to those of known rock types while looking for other identifying characteristics.

How do I know what kind of rock I have?

Look for crystals in igneous rocks. Examples of igneous rocks are gabbro, granite, pumice and obsidian. Metamorphic rocks are rocks that have become changed by intense heat or pressure while forming. One way to tell if a rock sample is metamorphic is to see if the crystals within it are arranged in bands.

Gold is unaffected by vinegar because it is a stable metal and will not react with oxygen. That means it will not change color, develop crystals, or disintegrate. If the sample is iron pyrite (Fool's Gold) or chalcopyrite, it may remain the color of gold, but will begin to form crystals while it is submerged.

How can you tell if a rock is a diamond?

The only hardness test that will identify a diamond is scratching corundum. Corundum, which includes all rubys and sapphires, is 9 on the hardiness scale. If your suspected diamond crystal can scratch corundum, then there is a good chance that you found a diamond. But NO OTHER HARDNESS TEST will identify a diamond.
