Gemstones are a type of natural mineral, found buried beneath the ground or trapped in rocks.
Gemstones are magical gems that have the ability to have spells bound to them. Gems are sought out by numerous intelligent species, most notably Dragons, who eat them as part of their diet. Equestria is particularly rich in gemstones, in contrast to the Zebra homeland which was mostly devoid of them.
Gemstones are acquired commonly by mining. Another method for harvesting gemstones was rock farming, which supposedly caused gemstones to grow bigger inside the rocks containing them.
Gemstones are sometimes necessary in a creatures diet, such as Dragons and certain cyberponies. Gemstones can most notably be made into Talismans, which can be used to create and power advanced arcane technology and enchanted items/weapons.
