If they enter the officers' line, they may eventually serve a year as Worshipful Master of the lodge. Past Masters retain this title. The jewel should be returned to the lodge when the PM dies. Most Masons also possess a white lambskin apron. If they served as master, or a higher post, they should also have elaborately embroidered aprons from those offices.
Most Masons also have an engraved membership certificate.
These degrees are open only to Master Masons, but have a administrative structure unconnected with the Grand Lodge. I'm kind of vague on titles here. The symbol for Chapter is a keystone with a circle of letters on it. I don't really know enough to comment on. Knights Templar have rather spiffy uniforms derived from those of Union Admirals during the Civil War, including a bicorne hat.
