A compass including a decorative container and a bearing is disclosed. The decorative container is disposed on top of the bearing while a base for spire is arranged on surface of the container. A symmetrical C-shaped balancing stand has two brackets for accommodation of heavy objects on bottom of two sides thereof. A magnetized bar is transversely arranged on the symmetrical C-shaped balancing stand and a center point of the magnetized bar aligns a central shaft of the balancing stand. A projective spire is arranged on center shaft of the bottom of the balancing stand for being located on the base for spire so as to form a pivot point for rotation. Therefore, the balancing stand rotates freely above the decorative container and the magnetized bar thereof aligns with earth's magnetic field so as to drive the balancing stand to rotate and indicate directions.
