I have been looking at someThree Stone Diamond rings for our tenth anniversary. I have a few prices from some reputable stores in our area. I also have been starting to take a peek on the web for some rings. Is it worth the potential hassle to buy from some of these sites? The prices are somewhat lower plus the fact that there is not any sales tax. I am having a hard time trying to find some sort of ratings on these stores. The only stores that I have looked at are the first few that come up in a "google" search for diamonds. Any help or direction into this would greatly appreciated.
