I can use some google/ebay help...

To get the really nice tension settings I'd like, it looks as if I'll probably have to order from the US. On top of that, because a tension setting cannot be resized by cutting, I will require very exact ring size...

At this point I'm thinking of using a temporary ring for the proposal and then getting a measurement for the final ring which would be here about a month later. I can have the real diamond in my hands at the time of proposal though.

So I'm looking for a cheap ring that doesn't look like it was designed for a gypsy, a whore, or an 80 year old. Nor something that just looks like it's more expensive than the real ring to come. On ebay most of the fake stone rings include a monster rock designed for tacky show. I'm looking for a rather simply ring with a 0.5 to 0.75ct "sized" stone (cubic zirconia, plain glass whatever).

Here are some of the settings I'm trying to decide on for the final ring:

If I was buying the setting locally, many jewelry stores would let me borrow a ring, but I don't have this luxury. I'd really like to get a GelinAbaci setting. There are many more styles on the GelinAbaci corporate site that I also like.

Obviously in a cheap ring I'm not looking for a tension setting. Something using standard prongs but as low profile as possible would be ideal. I've been unsuccessfully combing eBay and am about to start on Google...
