The X-Shaped Jewel is a quest item from The Legend of Zelda: Oracle of Seasons. This orange Jewel is found on an island off the Western Coast. When Link lights the Torch south of the Hero's Cave, a bridge appears, granting access to the island. After using a Mystery Seed on the question mark-shaped patch of earth, a Mini-Moldorm, known as the "Black Beast", appears. Upon its defeat, a chest appears that contains the X-Shaped Jewel. This jewel, along with the Square Jewel, the Pyramid Jewel, and the Round Jewel, is required to gain access to the Tarm Ruins.
