These guys' mistake was investing their skill points into coal mining. You're not getting rare jewels in there, no matter how much you tell yourself you might find a diamond. They don't spawn in coal mines. You're guaranteeing a permanent and progressive debuff (Black Lung) for maybe some quartz, pyrite and dolomite. Vendor trash.
Uh, the numbers are clear, noob, coal mining sells that "vendor trash" at a much higher profit per hour than gem mining.
