The Island Made Of Gemstones

The video explores Zabargad Island in the Red Sea, known for its rich deposits of Peridot, a gemstone-quality olivine. The island's geological formation is linked to the Earth's upper mantle and possibly the East African Rift Valley. Historically, it was a major source of Peridot, with the largest ever found weighing 311 carats. The island's composition is mainly peridotite, an igneous rock, and similar formations are found worldwide, including in Arizona.
