Well, first, blue nile doesn't give a hoot about the HCA. They use other factors to rate price. I suspect the table sizes may explain the differences in price: the more expensive one has a smaller table, so *might* give more fire, so they charge more... The inclusions may be more noticable in the more expensive stone too, who knows.Date: 5/9/2008 12:11:53 PM

Hi,
I looked at some Blue Nile diamonds
This one http://www.gia.edu/reportcheck/index.cfm?fuseaction=home.showReportVerification&reportno=16699911&weight=0.83 costs £1883
This one is a Blue Nile signiture cut diamond, one of their creme de la creme diamonds http://www.gia.edu/reportcheck/index.cfm?fuseaction=home.showReportVerification&reportno=16607917&weight=0.83 it costs £2151
They are both 0.83 ct H, VS2, no fluorescence, GIA triple excellent (cut,symmetry & polish). I ran them through HCA tool and it gave the cheaper one a rating of very good on all criteria it came out with an overall rating of 2.7 very good. The more expensive one had: -
Light Return Very Good
Fire Good
Scintillation Good
Spread Very Good
Overall 3.2 Very Good
The only difference I can see is the cheaper one has feather and the more expensive one has cloud. There is a $509 diffrence between the two. How come the cheaper one rates better via the HCA? Surely it should be the other way around???
Remember the HCA doesn't really let you choose between 2 diamonds though. A 2.7 and a 3.2 are really the same score--they are both non-ideal. Many here, including myself, would reject those diamonds because they score over a 2. Diamonds that score under a 2 have been cut with *complimentary* crown and pavilion angles, and have nice tables and depths.
As another aside, although some like BN, it isn't often the first choice for many PSers. BN doesn't have an upgrade policy, which is a turn-off for many, and they don't usually have the stones in-house. This means that BN has not personally seen and inspected the diamonds and determined that they are awesome. Places like Whiteflash and Good old Gold have dimaonds in house that someone has looked at and determined that the stone passes muster. So if you are a newb, buying from one of those places is great because a real expert has already looked at the stone, and decided to BUY IT. WF and GOG will only put out their own money to have stones in house that they think are good deals, and have great optical performance (or in some cases they are just a good deal...but this may be the exception). So this takes the guess work out to a degree, because the diamonds have already gone through one level of selection.
I'd recommend starting your search with them.
