The diamond insignia appearing on cadet first sergeant chevrons is less than 1 square centimeter in size and yet its propriety is hotly debated. The short version of the Saga of the Diamond is that yes, indeed, they are authorized for wear by CAP cadets in the grades of C/MSgt, C/SMSgt, and C/CMSgt. If you require a more detailed explanation of why that is so, please so this page.
