The Masonic Royal Arch Ribbon is a symbol associated with the Royal Arch Masonry, which is a branch of Freemasonry. The Royal Arch is considered the completion of the symbolic journey of a Freemason, and it is often seen as a continuation or completion of the Master Mason degree.

The ribbon you mentioned likely refers to a piece of regalia worn by members of the Royal Arch Chapter. This ribbon is typically worn around the neck, similar to a necktie or sash. It is often color-coded to represent different offices or ranks within the Royal Arch Chapter, and may feature various symbols and designs associated with Royal Arch Masonry.

The colors and designs of the ribbon can vary depending on the specific jurisdiction and tradition within Freemasonry. Each jurisdiction may have its own customs and variations in the regalia. If you are a member or seeking to become a member of a Royal Arch Chapter, it's best to consult with your local lodge or chapter for specific information about the regalia used in your area.

Please note that Freemasonry is a fraternal organization with its own rituals, symbols, and traditions. Information about its practices may not be widely available to the general public, and some aspects may be kept confidential among members.
