Within the Big Island of Hawaii is a fascinating geologic oddity. There exists a green beach which is completely filled with the gemstone peridot. This beach, referred to as Papakolea Beach, is located near the southern tip of the island. So, how did this gemstone filled beach form? This video will discuss this green beach came to be, and mention the scope of this geologic wonder.
