The Deathly Hallows consist the Elder Wand, the Resurrection Stone and the Cloak of Invisibility. The symbol was actually mistakenly adopted one of dark Wizardry ever since Gellert Grindelwald used it as his personal symbol. If you are fortunate enough (or unfortunate, depending upon your perspective) to own all three, then it is rumored that you would become the 'Master of Death'. Not a single Wizard or Witch had ever held all three Deathly Hallows at once, not even Harry! The cloak of invisibility is just one of the three powerful magical objects that are symbolized in the Harry Potter Deathly Hallows Earrings.
Our Deathly Hallows Drop Earrings may not have dark magical powers, but they will certainly make you feel like more than just a Muggle.
