Gems form in many places like inside volcanoes. Why do they form in volcanoes because there are many chemicals that cumbin under high pressure and heat.It is mostly a misconception that gems form inside the volcano in reality they form in rocks and cavities inside the earth where the needed chemicals are found. They also do not form as these gems that you find at the jewelry store.They Can also be im perfect with a lot of impurities. Sometimes these impurities are separate gems in their own right .They can make or break a gem riterly. There are gems that form around or inside other gems like watermelon tourmaline. It is a red tourmaline covered by a green tourmaline .Sometimes the impurity mite is a metal like gold in quartz.Can come in many varieties.Like green ,smoky , and blue just a few that I know of.
