The Freemason’s ornaments are three jewels, being the square associated with the Worshipful Master, the level of the Senior Warden, and the plumb-rule of the Junior Warden. Those who are entrusted with them must possess great talents and worthy of the offices they hold. When the Lodge is at labour, the jewels of their office are worn on a collar about the neck. A Past Master of a Lodge is entitled to wear a pocket jewel denoting his former station and rank.
