I bought an ideal agsl certified F color vs2 diamond stud 2 weeks ago, but when I received it I was very dissapointed. I''ve seen cubic zirconia with more brilliance and fire than it. Everyone around me has also commented on how dull it appears. I''ve went to a nearby store and compared it with other ideal stones and I am almost certain that the stone from bluenile is not an ideal. Can an ideal stone be dull and lifeless if given an ideal grade from agsl? I''m thinking about giving bluenile another shot, is it worth it? I''m somewhat reluctant after this experience.

Which stone would be a better choice? Stone 1 and 2 has a $30 difference while stone 3 is $150 cheaper. Which one would you recommend? Thanks for all the help in advance.

Can you also post the crown and pavillion angles (if available) for these stones? I''d use those values in addition to the table and depth percentages in the Cut Advisor tool located under PriceScope''s Tools link above. Perhaps an HCA score can reveal a little more information on the diamond.

Not enough info on these. Have you read the tutorials under knowledge to learn the best proportions of an Ideal Cut diamond? All the info you need is there, it will help you a lot. I don't like the info given on any of these so far, depths and tables aren't the best. Cut is key for a beautiful diamond, far more than the colour and clarity, time spent learning about cut is time well spent.

If you don't have the time or inclination to spend reading up and sifting through diamonds and wish to purchase quickly, I would recommend you talk to Whiteflash, Wink Jones, Good Old Gold, James Allen, Bill Pearlman etc and tell them what you want and they will find you a beautiful cut diamond within your budget and fitting your other parameters. These guys also have much more info on cut quality such as Idealscope images, Brilliancescope etc plus their very expert eyes plus in many instances the diamonds are in house so they can look at them for you.

Start reading here if you want to http://diamonds.pricescope.com/crn_pav.asp then use the blue column on the left to research further down the list.

I hope this helps.
 
Well if you are looking for ideal cut, you need to start with GIA certs that say Excellent for cut and not very good. Not all GIA excellents would also be AGS Ideal, but that is a good place to start. Aim for a depth beteen 60-62 and a table of 55-58. Some here even narrow that down even further, but it gives you a quick way to know if a stone is likely to be ideal. Then you can get all the other numbers.

If you look at GoodOldGold, WF, some of James Allen's, etc. you'll find more info on the stones.

actually, this isn''t the best way to pick a diamond and it will certainly not guarantee an ''ideal'' diamond. the gia system is more than a little flawed... not only will some (quite a few) gia excellents not get ags ideal, but some gia ''very good'' stones WOULD get ags ideal.

having the crown and pavilion angles is very important and if you are looking at gia diamonds, getting a seperate sarin done would be beneficial so you could sort out the rounding that was done by gia.
in short, i would stick to newly graded ags diamonds (with light performance grading).

merc, there is a slight chance that one of those would be nice, but the range of angles that would work with a 59/60% table is much smaller. it would take much trial and error in viewing (or a sarin measurement) to find the right 60/60 combination. you are safer to stay in the range diamondseeker mentioned for table size. or, of course, looking for a new ags grading report.

best of luck!
 
Belle, you know I understand your point, but for someone looking through BlueNile trying to find an Ideal cut within the GIA very goods would be looking for the proverbial needle in a haystack! I was just thinking the odds would be a LOT higher if they looked within excellent cuts and then inserted the numbers in the HCA. If they were looking at WF ES, then yes, we know that they can find AGS ideals within GIA VG.
 
I would tend to go by enlarging my searches with vendors who have more cut info and for sure consider the GIA VG's etc but get more info on the contenders to confirm cut quality. I don't look at BN that often to really see the best way to search but I imagine it might take a little more work to pick the best of the bunch, especially with the new GIA rounding.

Merc the really shoot for the best cut you can get, it is worth the time you spend on it. You will especially notice the difference with a well cut diamond after having one which didn't perform well.
 
I would return that diamond from BN ASAP. Yes, ideal cuts don''t guarantee light return and brilliance. You have to see it with your eyes to see if it is pleasing to you. Look at some of the vendors here who can find you a bright diamond with tons of sparkle.
 
I was really surprised though. I thought if AGSL certified it to be ideal then it would reflect a lot of light. The bluenile diamond looks more like glass.
 
i would choose none of those you listed.

look for something with table between 55-57; depth between 60.5 and 61.9; EX EX or ID ID polish and symm; and a GIA EX or VG (both will be promising) or AGS0. typically an AGS0 will be a beautiful stone, this may be an old one before they changed their grading? in the past AGS0 did not mean a beautiful stone, but since they have changed their grading scale, it''s said that an AGS0 should be a fab looking stone.
 
What are the measurements on this stone? What kind of HCA score did it get?
 
wow who knew that BN had so many meh stones !!!

I went through all their signature ideal and ideals for a D/E/F VS1/VS2 in the .40-.50c range and there were tons of stones (180 I think?) but only TWO that I would actually consider. Some of the ideal's for me had better #s than the Sig Ideals.

Those are the two. It seemed like the rest of them listed either had 62%+ depth OR slightly thick or thick girdles OR both...and those are two things I don't like in a diamond.

Both of the above have great angles, great table and depth, thin-medium girdles and are E/F VS ... I would buy either of those and check them out. They both also have AGS certs and are ID/ID. Good luck and keep us posted!!
 
that one looks good, i notice that alot of the smaller WF stones have 41 pav angles, which isn't my cup of tea but that's splitting hairs..i'd rather have a 41 pav angle than a thick girdle or 62+% depth. the idealscope on that one is sweet though.

here is another one that is $200 more but i like it a little better from the numbers. the angles are spot on:

both the stone you listed and this one i posted were cut to be ACA branded H&A's but something made them miss the mark, so WF puts them into their Expert Selection area, visually you will NOT see a difference between the ACA and the ES's meant to be ACA's...I have owned 3 (I'm on my third ES!) and I love them. It's all about inventory and budget.

and not like this is any secret but i would rather buy from WF or a PS vendor who has the stones in house with lots of information on them as well as IdealScope images than a Blue Nile anyday. but it's just my preference.

good luck!!
 
The idealscope image on this one looks great to me! E VS2 is very, very nice as well!
