The regalia worn today was first designed for and worn by the members of the London Bon Accord Mark Lodge in 1856. A Mark Master Mason wears an apron similar to that of a Master Mason in the Craft except that the Mark apron is bordered with light blue with crimson edges. He also wears a breast jewel in the form of a keystone suspended from a ribbon of light blue and crimson. The Installed Mark Master’s apron is likewise similar to a Craft Installed Master’s apron. Also, like the Craft, when a brother receives Provincial Grand Rank or Grand Rank the light blue is replaced with Garter blue.
