People can make money from rocks, but they are not as valuable as minerals. Many people tend to confuse the two. A rock is a common stone such as limestone, sandstone, marble, granite, and slate. These materials are more commonly used as building or "facing" materials. Minerals consist of such stones as quartz and its other cryptocrystalline forms such as agates, Carnelian, and Jaspers. These, along with many other types of stones, are all called 'Semi-precious' gems. Then, there are the stones like Rubies, Garnets, Amethysts, Emeralds, and, of course, diamonds. These are considered to be 'precious' gemstones.
