The Cryptic Degrees, also known as the Royal and Select Masters, are a series of degrees in the York Rite branch of Freemasonry. These degrees are considered an extension of the Master Mason degree, and focus on the symbolism and teachings of King Solomon's Temple. The regalia worn by members during meetings and ceremonies is designed to distinguish them from members of other branches of Freemasonry.
One of the most recognizable pieces of Cryptic Degrees Regalia is the apron, which is typically made of white lambskin and adorned with a blue border and various symbols that are specific to the degree. The symbols on the apron often include the triple tau, the letter "G" and the working tools of the mason such as the plumb rule, level, and trowel.
Another important piece of regalia is the collar, which is worn around the neck and adorned with the emblem of the degree. The emblem typically includes a representation of the triple tau, and other symbols that are specific to the degree.
In addition to the apron and collar, members of the Cryptic Degrees also wear a jewel, which is typically pinned to the lapel of a coat or jacket, and is specific to the individual's rank within the degree. The jewel is usually a pendant that can be of different shapes, with a representation of the triple tau, and the letter "G"
Overall, Cryptic Degrees Regalia is an important part of the tradition and history of Freemasonry, and is worn by members as a symbol of their commitment to the principles of the degree. These degrees are considered an extension of the Master Mason degree and are not widely practiced in all jurisdictions.
