The Dark Mark. The symbol of Lord Voldemort and his Death Eaters. It refers both to a magically induced brand that every Death Eater bears on his or her inner left forearm, and to the same symbol conjured in the air by the spell Morsmordre. The Snake refers to the Slytherin house's ability to speak Parseltongue, or as Ron says "Snake Language". Featuring an Emerald Green rose cut Chalcedony in place of the skull on the true Dark mark symbol. A true symbol of the Slytherin house (but not all members). These Ear studs are an Inch and a half in length and come complete with sterling silver ear nuts as well as silicone backs for whichever you may prefer!
