I bought a sapphire/diamond eternity band from Tiffany for something like $7,000. Knowing that the ring was way overpriced as it was from Tiffany, I looked at Blue Nile, found the same ring for 1/3 the cost, and ordered it. Comparing the 2 rings side-by-side, we had to be careful that we didn't mix them up, as they were identical in design, stone size/quality, and overall look. The only difference was that inside the band of the Tiffany ring it said 'Tiffany'. We showed the rings to several people and asked them which was the better quality ring. No one could really say that one was better than the other, they couldn't tell the difference between the two. The Tiffany ring was returned.
