I have narrowed down my choices to two stones with GIA certificates:

the first diamond is J color, 0.90ct, SI1, triple excellent, HCA=1.7 (within TIC range) (the price is around $4,300), Table: 54%; Depth: 62.2%; Crown Angle: 35.0; Pavillion Angle: 40.8 Girdle: thin to medium; Culet: None


The second one is G color, 1.02ct, I1 (the inclusion is very minor for an I1 clarity), very good cut (Excellent for symmetry and polish), HCA = 0.8 (within FIC range) (price is $4,500), but it has medium blue fluorenscense. Table: 57%; Depth: 61%; Crown Angle: 36.0; Pavillion Angle: 40.0. Girdle: thin to slighted thick; Culet: None.


I really cannot decide which one to pick. The picture shows that the first one looks more eye-clean, but it is under 1 carat, and has a J color. However, the second one has minor inclusion which may or may not be completely covered by a prong, and I am also not sure whether the fluo will make the stone look milky. Any suggestion or opinion is much appreciated!
 
Post the GIA report number, idealscope image if available.
 
Thanks for the reply.

Idealscope image is not available. GIA number: 2131569698; 2131606920

Many thanks for the help!
 
Here is more information on GIA certificate:

0.9 ct one: Table: 54%; Depth: 62.2%; Crown Angle: 35.0; Pavillion Angle: 40.8 Girdle: thin to medium; Culet: None
1.02 ct one: Table: 57%; Depth: 61%; Crown Angle: 36.0; Pavillion Angle: 40.0. Girdle: thin to slighted thick; Culet: None.

Thanks
 
Warning flags:

I would immediately toss the 1.02 because of the 40.0 pavilion angle. That basic pavilion/crown pairing will go dark when viewed close-up (this is an obstruction-issue; a shallow angle combo which darkens faster than other combos as the viewer's head comes closer, blocking the light). Even as a pendant stone, which would be viewed father away, it's only predicted to be AGS4 in performance. The I1 feathers also require in-person scrutiny to see what kind of issues they may cause in setting and future wear. FWIW the medium blue fluorescence would be a non-issue unless you exposed it to UV light in a dark place like a dance club - where it would just glow eerily at you.

The 0.90 has measurements I like. The 54% table is somewhat uncommon, and paired with a CA to give it a nice high crown. Those primary angles are reminiscent of traditional LK and T&Co preferences. Be warned that with the dossier report there is no way to know how significant the grade-setting cloud is. And since it's the only inclusion named I'd want it examined to see if it's one of those rare SI1s where a massive cloud interferes with the optics.

Thank you very much for the detailed explanation! I have asked JA's expert to examin the 0.9 stone. Once they confirm it is eye clean, I will go with it! Thanks!

I don't know what your max budget is but this one looks really nice. Call BGD for discount, I believe it is 5% off with wiring price for pricescope members.

Thanks for the recommendation. However, I have already placed my order for the 0.9 ct diamond. I am looking forward to receiving the stone soon!

Good pick. An I1 stone with the grade making inclusion being a feather may be a durability issue.
