I have them both. The first one I bought first, then I bought the second one second - LOL!
The first one tends to get a little heavy and is more substantial as said by several here. Also, it tends to get "dirty" very quickly and needs to be cleaned and polished to maintain its beauty more frequently than the second piece.
The second ring is a very fun ring and I tend to wear it a lot more than the first one (probably partially due to the weight difference). It is a light and airy piece but I am able to "dress it up" more than I would have thought.
But both pieces are wonderful! Enjoy.
