Gemstone mining, an ancient practice deeply intertwined with human civilization, involves the extraction of precious and semi-precious stones from the Earth's crust. Revered for their unparalleled beauty and scarcity, these gems have carried immense cultural, economic, and spiritual significance over millennia. This intricate process encompasses the retrieval of valuable gemstones from the Earth's surface or subterranean depths. Diamonds, rubies, emeralds, and sapphires, among others, are highly sought after for their exquisite allure and applications in diverse sectors such as jewellery, technology, and healthcare.

Gemstones are broadly categorized into three types: precious gemstones, semi-precious gemstones, and organic gemstones. Precious gemstones like diamonds, rubies, emeralds, and sapphires are rare and highly valuable, while semi-precious gemstones like amethyst and turquoise are more common. Organic gemstones, such as pearls and amber, originate from living organisms.
