So, I couldn't bear to wait, and went to pick it up today after all. It is gorgeous (or at least I think it is!). It is funny to actually hold it in my hand after staring at it online for so long.
The experience with you in particular and Whiteflash in general has been truly enjoyable, and I'd like to express my thanks. It was a big leap of faith to go from buying from a ""bricks and mortar"" jeweler to purchasing online from Whiteflash, but I now know it was the right way to go. The wealth of information provided, the ability to actually have some choices, and your extensive help made Whiteflash a fabulous experience.
On to the next big step - actually popping the question! We'll see how that goes!
Once again, thank you for all of your help and patience.
