I've ordered rings from Moonstone before and in my experience, they tend to run a little large. This ring is perfect and beautiful as they always are, but I do recommend sizing down - I'm normally somewhere closer to a 6 but a 5 fit much, much better.
I really love this ring! The ouroboros is one of my favorite symbols and I've been looking for a cool and not overly expensive ouroboros ring for a long time. I'm also a big fan of Robert Jordan's Wheel of Time series, and this ring is very much how I envisioned the Aes Sedai great serpent ring would look. It also seems to be of very good quality.
It does seem a little big for a size 6; it only fits one of my fingers, but I like it so much I may get another in size 5.
I've been looking everywhere for a ring like this for my boyfriend. I got this ring for him for Christmas, and he loved it! It's really great quality for the price. I've seen many similar rings in this price category but none of them compared to the quality of this ring.
