Hey guys,

This past weekend I went to go shopping for a round diamond, and I was wondering if I could get some help from you guys. I will really appreciate your opinions and advice on this.

So I need help choosing between these two diamonds since these were the only one's in my budget that they had.

Diamond #1

Round GIA report
Measurements: 7.63 - 7.74 x 4.45 mm
Carat Weight: 1.57
Color Grade: K
Clarity Grade: VS2
Cut Grade: Good

Proportions:
Depth: 57.9 %
Table: 59 %
Crown Angle: 30.5°
Crown Height: 12.5 %
Pavilion Angle: 40.6°
Pavilion Depth: 43 %
Star length: 45 %
Lower Half: 80 %
Girdle: Very Thin to Medium, Faceted
Culet: Very Small

Finish:
Polish: Excellent
Symmetry: Very Good
Fluorescence: Faint

This Diamond was my favorite. I was worry about the color but when the sales rep compared it with a similar size and color of "I' it was almost the same. She even said maybe the GIA made a mistake on grading this diamond. She is some sort of GIA graduate and said would colored it a "J".

Diamond #2
Measurements: 7.34 - 7.39 x 4.49 mm
Carat Weight: 1.52
Color Grade: I
Clarity Grade: SI2
Cut Grade: Excellent
Proportions:
Depth: 61.0 %
Table: 59 %
Crown Angle: 35.5°
Crown Height: 14.5 %
Pavilion Angle: 40.6°
Pavilion Depth: 43 %
Star length: 55 %
Lower Half: 80 %
Girdle: Medium to Slightly Thick, Faceted
Culet: None

Finish:
Polish: Excellent
Symmetry: Very Good
Fluorescence: None

This was another good Diamond but there was some white spot in the middle that I was disappointed. But the measurements looks good, I think. When I saw both diamonds I liked diamond #1 probable because it looked way bigger almost to a 1 3/4ct because she brought it out one with that size. So I thought I was getting a bargain and they are both the same price at around 8700. What do you guys think? I will really appreciate you guys opinion.
Thanks.

Well, the first diamond gets this score on the HCA:

Diamond 1
Light Return: Good
Fire: Excellent
Scintillation: Excellent
Spread or diameter for weight: Excellent
Total Visual Performance 2.1 - Very Good - Worth buying if the price is right

The second diamond gets this score on the HCA:

Diamond 2
Light Return: Very Good
Fire: Excellent
Scintillation: Very Good
Spread or diameter for weight: Very Good
Total Visual Performance 1.7 - Excellent within TIC  range

So it looks like diamond 2 is a better performer, which makes sense given its better cut grade, but I would not be happy at all with a stone with visible inclusions. The first stone is okay IF THE PRICE IS RIGHT... but I am not sure it is right!

If I were you I wouldn't get either and would go for this one instead. GOG has great customer service, sells stones with killer optics, this one is the same size as diamond number 1 but with much better numbers AND it is almost $1000 less expensive if you use bank wire! Check if it's eye clean.

I also dig this and this, but they are a little smaller than the ones you are considering, though they are also less expensive and will be gorgeous!!

Welcome!

I would personally pass on the first diamond, it has a shallow crown angle and also a very thin area of the girdle, so it is possible the diamond could be more prone to chipping.  If you really want this one, then I would suggest you get a independant appraiser to check the diamond out for this reason.  I prefer the proportions of the second diamond, but as you say you can see a visible inclusion, I would again suggest looking for more stones, you could make it a little easier perhaps by looking at AGS0 and GIA Excellent cut grade, then evaluating each diamond from there.

That is a beautiful diamond DD posted, would buying online be an option for you?

When a horse dies, the memory lives on because an enormous part of his owner's heart, soul, very existence dies also...but that can never be laid to rest, it is not meant to be...
