On completion of the first Cryptic Degree of Select Master, a Companion is invested with the jewel of the Order, which consists of a skeleton equilateral triangle of white enamel, surmounted by a gold Imperial Crown suspended from a crimson ribbon.

When he has passed through the remaining three Degrees, he is entitled to wear the triangular apron, which is of white kid with a border of crimson silk edged with gold braid. Officers of private Councils wear crimson collars, from which is suspended a gilt jewel of the emblem of their office.  The apron of the Order of Royal & Select Masters is unique from other degrees in Freemasonry due to its triangular form. The Triangle is of course an emblem of the Deity and holds particular significance for Freemasons.
