Gem

A gem is a precious or semi-precious stone that has been cut and polished for use in jewelry or ornamentation. Formed naturally over millions of years under intense heat and pressure within the Earth's crust, gemstones such as diamonds, rubies, sapphires, and emeralds are valued for their beauty, rarity, and durability. Their appeal lies in their unique color, clarity, and brilliance. Beyond jewelry, gems can also have cultural significance or symbolic meaning. They are considered valuable collectible items and are often associated with wealth and craftsmanship.
