Top best answers to the question «Where are gemstones mined»
Most gemstones form in the Earth's crust, approximately 3 to 25 miles beneath the Earth's surface. Two gemstones, diamonds and peridot, are found much deeper in the Earth. Diamond forms in “kimberlite pipes” that originate in the Earth's mantle (>125 miles) and end at the surface.
