When you scratch a rock on something, it’s often referred to as testing the rock's hardness or conducting a scratch test. This is commonly done to identify minerals using the Mohs scale of mineral hardness, which ranks minerals based on their ability to scratch one another. The process can help determine the composition and characteristics of the rock or mineral being tested.

The scratch test is used to determine a rock's hardness on the Mohs scale, which ranges from 1 (softest) to 10 (hardest). By scratching a rock with a known mineral or material of a specific hardness, you can compare the scratch to known hardness values to classify the rock. This test helps in identifying the rock's mineral composition and potential uses based on its hardness.
Emeralds are typically dark green and can have a shiny appearance. You can try scratching the rock against a piece of glass to see if it leaves a streak. In addition, you could take the rock to a jeweler or gemologist for a professional assessment.

But in online scratch card gaming you can always be sure that the scratch cards are always updated and you can always ask email or call support of the site if you want to know anything about stuff.

If two rocks cannot scratch each other, then they would have to be of equal hardness. A harder rock can always scratch a softer rock.
That would be Talc.
