This is the third ring I ordered. I ordered a six because I wanted to wear it on my middle finger. The first ring was not a size six, it was a five. I ordered a new one and it was yet again a size five. Next, I ordered a size seven. That fit much better. It's little big but I can live with that. As others said, it runs SMALL. Definitely, size up. It is fragile as others have said as well so be careful. That being said, I really love this ring. It's so pretty and I've received many compliments! I do recommend. : )
