Sith Eternal crest

The Sith Eternal crest, also known as a hex charm, was a dagger-shaped symbol of the Sith. The Strand-Cast Dathan had a songsteel amulet that had a fine chain with a Sith hex symbol on the end.

At some point long before the Galactic Civil War, this symbol was adopted by the Sith Lord Gol and his court.

The crest was adopted as the insignia of the Sith Eternal cult, whose Sith cultists adorned themselves with it. One such cultist was the assassin Ochi of Bestoon. Sith Eternal officers of the Final Order fleet wore specialized uniforms that included a kepi hat, which displayed the crest in the form of a sculpted metal piece.
