Despite this site originally being about Tiffany Jewelry, I have come to realize that there are just as many rings out there that look just as good as Tiffany products, but come at a fraction of the price. I have also recently discovered how terrible the diamond trade can be and am now firmly against buying real diamonds when you can get fake ones that look better than the real thing for less than $100!
Anyway, I found a couple of great websites that sell cheap rings and ended up buying a great ring from BeautifulPromiseRings.com. They have one of the best collections of sterling silver rings that I have seen on the net and they deal only in man made gemstones at great prices. They also run regular giveaways, so I thought this would be a great chance to spread the word.
I would love to hear about any other sites that you have found that sell cheap cubic zirconia jewelry.
