This ring is stunning and one of a kind! The first one I received had a defect, but I received a replacement in one day! The gold is authentic and polished- even after having my hands in water often. The turquoise is an amazing complement to the 18k gold. This ring is "go anywhere, anytime" and I'm looking for more Ross Simons jewelry, besides all the pieces I already have. Please give this ring a try- you will love it.

Pretty

Gem Type: Created Turquoise, Ring Size: 8

Pretty ring. Definitely size up due to width. Less substantial of a ring. More dainty than I had hoped but still very pretty.
