Have you ever found a beautiful gem? Have you ever wondered what is in rocks? Did you know that red diamond is one of the most rare types of gems? Rocks and gems both have something in common, but have you ever wondered what makes rocks and gems different?
Gems
Gems are also known as precious stone, jewels, or just stone. What is a gemstone? A gemstone is a piece of mineral crystal, when the gem is cut and polished, it is normally used for jewelry. Why do gems have so much value? When the gemstone is uncut, it tends to look like a rock. When the gem goes through the polishing process, that is what gives the gemstone it’s value. What is the study of gems? The study of gems is called …show more content…
What is a rock? A rock is a natural substance on Earth that contains one or more minerals or mineraloids. All rocks are made out of minerals. Are there different types of rocks? Yes, there are three different types of rocks. One of the rocks is called sedimentary. A sedimentary rock have particles of sand, shells, pebbles, and other materials. When all of these particles are together, they create sediment, which is why those type of rocks are called sedimentary rocks.You can find sedimentary rocks in oceans, rivers, or deserts. Shale, sandstone, and limestone are the most common types of sedimentary rocks. The mineral that forms those rocks is called feldspar. The second type of rock is called the metamorphic rock. The metamorphic rock is actually made up of the other two rocks, sedimentary and igneous. Slate (a type of metamorphic rock) is formed from shale (a sedimentary rock). Same with marble and limestone, marble (a metamorphic rock) is formed from limestone (a sedimentary rock). Metamorphic rocks can be formed by pressure deep inside the Earth. Metamorphic rocks make up the coastline of Brazil. The last rock is the igneous rock. What forms igneous rocks? Igneous rocks are formed by the cooling of the molten magma that appears on the Earth’s surface. There are two types of igneous rocks, the extrusive igneous rock and the intrusive igneous rock. Extrusive igneous rocks cool and solidify faster than the intrusive igneous rocks do. Some examples of the intrusive igneous rocks are diorite and granite. Some examples for the extrusive igneous rocks are obsidian, and pumice. You can find igneous rocks on the face of the
