This is a Tudor silver-gilt hat badge, dating to the 16th century. The back of the badge is intact with the 'S' shaped pin, used to secure the jewel to a hat. These types of hooks are a characteristic category of Tudor dress accessory used to embellish the hats of high-status individuals and are discussed by Gaimster et al (2002: 169-173). See also SUR-C6DA03, YORYM-589235, SWYOR-C08232 and NMS-AA0079 for further types and discussion.
This is a nice example in dood condition from a private collection of Tudor hat pins
