Diamonds: Amazon vs. Blue Nile

When really bored, after I have caught up on Post Secret, Best-of-Craigslist, and a few of my other favorites, I sometimes find my way to Blue Nile or Amazon.com checking out diamonds.  Why?  Well, you always want what you can't have.

I decided to do a little quantitative analysis between the two sites.  It would be extremely difficult to find two diamonds with all of the same characteristics, so I focused on round diamonds and the main four characteristics: carat, cut, clarity and color (varying, very good, VS1, H).  I looked at diamonds from both websites that met these characteristics.  If the site had multiple of each increment, I selected the diamond with the lowest cost. Below are my results.  As you can see, Amazon was a little bit cheaper 'til it got to the heavy hitter, the 2.0 ct, when it was substantially cheaper.  Worthy of note, Amazon's selection was smaller than Blue Nile's, at least for these increments.

  1. There are other features to realize. One of them is fluorescence. and even if you have two diamonds that are classified to have a "very good" cut, you have to consider the which cut is closer to ideal or signature ideal. depth and table ratios are important and they can represent hundreds of dollar of difference between two diamons with the "same specs". In addition Blue nile diamonds (and most reputable jewelrers) come from non-conflict area and there is respectable name behind them and a certification from a national gemologist institute. So although this is not to counter your research, it is to offer any other reader, a different perspective. Anyhow, its all about research if you have the time, if you dont and you want to make sure you are buying a great stone then just go to tiffanys. Blessingas my friend thanks for your contribution.
    btw, huuuge difference when you hit the 2ct mark! interesting! thanks a lot!
