So on my new favorite website, Pinterest, I found this horcrux necklace. It was on Etsy for around $70. Well I loved the idea, but of course I didn't want to spend that much money!
Above is my inspiration for my own $10 version. It looks less eclectic, but I think it's a good substitute. I used two cheap charm websites to compile my horcruxes and Harry Potter-themed necklaces.
I also made a silver one, which is just general objects related to the series.
Each was less than $10, which includes the 30 inch chain! Take that, overpriced Etsy listing!
