Which independent state in the Persian gulf is called Island of pearls?

The independent state in the Persian Gulf that is called the Island of Pearls is Bahrain. The name "Bahrain" is derived from the Arabic words "baḥr" (sea) and "ayn" (spring), referring to the natural springs that dot the island. Bahrain is known for its long history of pearl diving, which dates back thousands of years. The pearls found in Bahrain were highly valued and were often used in jewelry. The island's economy was once largely dependent on the pearl trade, but it has since diversified into other industries such as oil and gas, banking, and tourism. Despite the decline of the pearl diving industry, Bahrain is still known as the "Island of Pearls" due to its rich history and cultural heritage associated with pearl diving.
