Hand Of Rathmore
From Tomb Raider Wiki
The Hand of Rathmore is the fifth artefact which Lara is looking for in Tomb Raider III Gold. It was a secret fifth crystal artefact, fashioned from the same meteorite from Tomb Raider III. It's unknown if it has any relation im activating the meteorite in the Meteorite Cavern, because Lara only needed the four main crystal artefacts to activate it.
