Geodes aren't literally diamonds in the rough, but they come pretty close. On the outside, geodes look like dull, ordinary rocks, but when you break them open, you'll find beautiful gemstones inside. Depending on the type of geode you have, these crystals may be clear quartz, amethyst, hematite, fluorite, or a vast number of others. Although simply hitting your geode open with a hammer may be the easiest way to break it open, this method is not recommended, as it damages the insides and breaks the geode into many pieces instead of two clear halves. A better way is to use a flat chisel and a hammer, two common tools that you might already have around the house.
