I've been looking for a place like this to learn about rings for several weeks! My gf likes the Ritani 2486 ring, but it is out of my price range, so I'm trying to find something similar and could use some help. I'm looking for a channel set ring that is narrow (2mm) because her hands are small. I've found this one that is similar, but I'd like to find one with arches that are more curved like they are on the Ritani. She also wants to have the diamond sitting low on the ring, so I need to stay away from large, long prongs. In addition, she has nickel allergies, so I need to stick with 18k gold or palladium. I'd like to keep the price under $800.
