I found myself drawn to people wearing those healing/reiki crystals with their bohemian style outfits on the internet and did some research. I finally found one that I may want to get, but it took a lot of narrowing down, because there were so many great options that I had to sift through.

There are tons and tons more online; this is just a fraction of what I managed to find. There are smaller options for a much cheaper price, but I was going for something longer. TheMagicIsInYou sells a ton of items in this area, and with reasonable prices.
