Aquamarine Island or St. Johns Island in the Red Sea
It is the largest group of the Gulf of Beans, the Red Sea in southern Egypt, covering approximately 4.50 km².
The island is one of the most important and oldest sources of peridot stone globally, and it is believed that it is the first place where peridot stone was discovered because it was known as the island of Aquamarine in ancient Egypt. Peridot was known in it from 1300 BC.
The island is famous for its bird sightings, and the most famous of which is the sunset falcon, diving underwater to see coral reefs and approaching rays, Moorish, octopus, and squid.
The island is surrounded by coral colonies that inhabit a wide variety of fish and other aquatic life. The coral reefs are located at a depth of 25 meters from the surface of the water.
Aquamarine Island produced the largest peridot stones globally, a stone weighing more than 310 carats, displayed at the famous Smithsonian Institute Museum in the American capital.
