Wearing a Slytherin necklace is a popular way to show the world which Hogwarts House you were sorted into. The jewelry can be worn for costumes, Cosplay, or simply because you like it.
Salazar Slytherin, the founder of Slytherin House, had the unusual ability to speak to snakes, an ability known as being a Parselmouth (the name for a person who speaks the snake language of Parseltongue).
The crest for Salazar's house has a serpent on it, so it should come as no surprise that many of the pendants also have a snake on them. Most are also adorned with the House colors of green and grey.
My youngest daughter informed me that she was she was sorted into Slytherin House and has enjoyed decorating her room with items that would be at home in Borgin & Burkes (in fact, some have come from there!). For her birthday we got her an official Slytherin robe from Universal Studios and I think we will get her a matching necklace for Christmas. The creepier and darker the better for her. What about you?
