This piece is very unusual indeed.
Trumpet brooches were made in Roman Britain between the second and third centuries A.D. In the words of the late Richard Hattatt, once the world's foremost authority on Roman fibula brooches:
"The mature British trumpet brooch is, at its best, a thing of considerable beauty and is found nowhere else in the world, other than the occasional stray."
Not only is this one of the most beautiful Roman trumpet brooches that has ever passed through our hands, but it, amazingly, still has a length of original chain attached to the headloop (Roman brooches were often worn in pairs, connected by a fine chain).
We don't think we will ever come across another.
