A 14th century bishop's seal discovered by metal detector enthusiasts will go on display at the Manx Museum for the first time on Saturday.
The silver seal, which was discovered by Andy Falconer, is described by historians at Manx National Heritage (MNH) as "incredibly significant".
Andy Falconer made the "once in a lifetime discovery" when searching in a field in the north of the island.
Curator of archaeology at MNH, Allison Fox, said: "It is a very rare find and an important part of Manx history."
