A gemstone is a precious mineral naturally found deposited on the earth surface or beneath. They are beautiful and highly valued gifts of nature that are found across Europe; from the length and breadth of the continent, starting from Portugal to Russia in the Far East. Some countries in Europe have little compared to some others that have a diverse range of gemstones.
Minerals on the earth crust form different types of crystals that are pleasant to the eyes. These gemstones only become highly valuable and beautiful after they are refined.
