🌎 Mineral and Gemstone Formation

Minerals and gemstones are formed through a variety of geological processes, including magmatic, metamorphic, and sedimentary processes. 🌊

• Igneous rocks are formed from the cooling and solidification of magma or lava. 🔥
• Metamorphic rocks are formed when existing rocks are subjected to high pressure and temperature, causing changes in their mineral composition. 🔄
• Sedimentary rocks are formed from the accumulation and compression of sediments, such as sand, silt, and clay. 🌀
