How to Identify Valuable Rocks

The unique properties listed above are the most valid ways you can identify a valuable rock.

After rocks were bought to the surface, some minerals dissolved but some didn’t and most got disposed of using different processes. If there seems to be nothing unusual about a rock, do not overlook it, the best way to inspect a rock is to check for the properties explained below.

1. Hardness

Hardness is one of the most notable characteristics of a valuable rock. To identify a mineral as valuable, it has to be able to resist scratch and it is also determined by its ability to scratch each other.

You can always measure the hardness and roughness of a valuable rock using a kit made for it or you can try the simple method of scratching with a hard object or fingernail.

Generally, the harder rocks are of more value than the soft ones. If your fingernail can scratch it then the hardness is rated at 2.5 Mohs or less. Those that can only be scratched with glass are rated at Mohs of 5 and 6.5. Diamonds have a hardness of 10 Mohs and can only be scratched by another diamond.

2. Color Inspection

The next important property to help you identify a valuable rock is the color. Color is not adequate for identifying crystals but it’s a defining factor. Most valuable rocks have multiple hues which is a result of impurities so you can look out for that.

3. Streak Test

The streak test is the typical way geologist tests the value of a rock. The color that comes from crushed rocks has a different color from the rock itself so you can rub the mineral on a streak plate to see if the color you get is different from the color of the rock.

A piece of unglazed porcelain can be used for the streak test. A jade rock will leave a green streak, while chalcopyrite leaves a black one.

4. Luster

Luster is simply how a rock reflects its light and valuable ones have a different light reflection than ordinary rocks. The two basic types of luster are metallic and non-metallic. Rocks that do not exhibit any type of luster can be referred to as dull, chalky, or earthy.
