What is the most common jewel in the collection?

One of the many Past Master and Past Grand Master jewels in the House of the Temple's collectionVisitors often wonder what is the most common jewel in the museum’s collections. It’s not a 14th Degree jewel or a 33rd Degree jewel—in fact, it’s not even a Scottish Rite Jewel—rather it is a jewel of the Blue Lodge.

The answer is a Past Master’s Jewel. A Past Master is one who served as a Master of a Lodge and the jewel symbolizes his term as an officer.
