This fob is relatively large compared with its peers. I believe It is cast out of brass.
The seal in the center tested as glass and it is partially red partially colorless. I think the Intaglio is molded. It depicts a man's profile, maybe a prominent ancient Roman or Greek figure. The facial details are very finely done, and did you notice his neck? He is obviously a powerful man.
The piece measures 1" by 7/8" over the base and stands 1 5/16" high, weight a quite substantial 13 grams.
