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.
