Elizabeth Short's Dahlia

Origin
"The Black Dahlia" was a nickname given to Elizabeth Short[, an American woman who was the victim of a gruesome and much-publicized murder. Short acquired the moniker posthumously by newspapers in the habit of nicknaming crimes they found particularly lurid. Short was found mutilated on January 15, 1947, in Los Angeles, California. Short's murder is one of the oldest unsolved murder cases in Los Angeles history.

Effects
When touched causes the wearer to slowly take on the properties of Short's mutilated corpse, feeling the pain associated with every injury, yet kept alive until the transformation is complete. The dahlia will slowly turn black as the effects progress and only has to be touched once for the effects to kick in.
