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.
| Amazon | Blue Nile |
0.5 ct | $1,340 | $1,345 |
1.0 ct |
$5,395 |
$5,815 |
1.5 ct |
$11,245 |
$11,780 |
2.0 ct | $20,535 |
$27,230
