Need help choosing ring

[DNICE850]

Hi,
I am trying to decide between two diamonds on blue nile.
They are both round shape, same carat size and price range. However, they differ in cut, color, and lab certification
They are both in my price range, with the AGS diamond costing $200 more. Which would be the best choice?
table, depth, and other measurements are roughly the same.

1) G, VS2, ideal cut, certified by AGS
It''s not blue nile''s best cut, but it is AGS certified and I read AGS is stricter when it comes to grading diamonds.

2) H, VS2, signature ideal cut, certified by GIA
The signature cut is blue niles best cut and diamond comes laser inscribed, but it''s not AGS certified.
My concern with this ring is that a GIA VS2 might turn out to be an SI1. The report also shows more inclusions than the report for ring 1.

Please let me know your thoughts.

thank you!

You''ll also need to post the carat weight, table %, depth %, crown angle, and pavilion angle of the both diamonds for people to be able to comment on the diamonds.

With these info, the experts in this forum will be able to comment on your choices when they trudge along

Thank you reigndeerz

, if you could post all the above info to include the girdle thickness, diameter measurement and star and lower girdle facet percentages we can go from there.

GIA graded VS2 should be very reliably graded.
Since GIA actually created the D/E/F/G.... colour system (and retain a set of reference stones for the purpose) and GIA also created the FL/VVS/VS.... clarity system, then they ought to be the world''s most accurate. But AGS are equally strict on colour/clarity (on balance). The only downfall of GIA is that their "Excellent" cut grade is a much broader and generally less strict set of criteria than AGS.

Diamonds are graded by humans. We all have our faults, with slightly different opinions, eyesight and so on. Even the time of day, day of the week, general tiredness or illness can affect how accurately and consistently we work. Which can mean that two different graders might give a different result for the same stone. However, I believe that GIA send each stone to at least two of their graders, with a senior grader making the final judgement if the two junior graders disagree.

Regarding one stone having more inclusions than the other......
There are "good" VS2 stones that are close to a bad VS1 and there are "bad" VS2 stones that are closer to a good SI1. I have a "good" SI1 stone and a "bad" VS2 stone. The VS2 is only slightly better than the SI1.
The location, size, number and type of inclusion set the grade.
But a single large inclusion may be more visible to the naked eye than several smaller inclusions. Also, a tight cluster of small inclusions can be more visible than more scattered inclusions.

Both show potential, the first falls within fiery ideal cut range ( FIC) which basically means it could show greater fire if the lighting is right. The second also shows promise but without images thats all we can say.

They both look good on paper. GIA is a *very* reputable lab don''t worry about them compared to AGS. Sometimes they can be a little more forgiving in their cut grading, which is why people favour AGS sometimes around here.
