has never been proved since crystals have been around for longer than humanity, highest possibility that the first crystals found by us was in a cave in africa, around today's egypt. they were actually looking for gold but they stumbled upon shiny clear rocks too :)
Africa in Egypt was the first place where discovers found on crystals
The exact country where the first crystal was discovered is uncertain; however, one possibility is a cave in Africa near modern-day Egypt. Ancient Greeks also interacted with various minerals, indicating a long history of human engagement with crystals. Crystals formed naturally on Earth billions of years ago, well before humanity arrived.
