Wearing or adorned with a gorget; furnished with neck armor or ornamental throat covering.
From 'gorget' (a piece of neck armor or ornament) plus the past participle or adjectival suffix '-ed', meaning 'equipped with a gorget.'
Adding '-ed' to a noun (like 'a boy with freckles becomes a freckled boy') is one of English's oldest tricks—'gorgeted' lets you instantly describe something as 'wearing a gorget,' which is especially useful in ornithology and heraldry.
