As usual, I am torn between size and quality. The only thing I am sure about is the setting, which is attached

Thanks in advance
 
I would prefer #2, but #1 could be good if I think it is from that vendor.

no idea on #3, lacks the crown and pavilion angles to make a judgement.
 
Welcome rodmichael,

Can you provide the crown and pavilion angles for the last diamond please? Also do you have any idealscope images for any of these please?
 
Thank you for your replies. I have since found a diamond in person and would like some feedback as I will likely be making a purchase this week.

1.31 ct
I color
SI1 Clarity
Round
Depth : 61.1
Table: 56.1
Ideal polish and symmetry
No Fluorescence
Measurements: 7.03, 7.08, 4.31
Crown Angle: 34.4
Pav. angle: 40.7
H&A: yes
AGS lab
approx 8k

I am hesitant about the I color but love the diamond. Any thoughts on the color, anyone?
 
no issue for me for I color but I am color insensitive.

Looks good on the numbers.
 
Could you link the stones....they all are potentially very nice.
 
A reliably graded I colour should be fine, as you can see the diamond in person ask if you can check it out away from the store lights as this should give you a better idea.
 
Weight:1.37
Cut:Ideal
Color:F

Depth:60.2%
Table:58%

HCA score: 1.1 (ex, ex, ex, ex)
Depth % 60.2

Crown Angle: 33.5
Pavilion Angle: 41

approx $7300, which I think is a steal. I have narrowed my search down to 2 diamonds, the other being:

Weight:1.31
caratCut:IdealColor:FClarity:SI1
Laboratory:AGS, H&A
Measurements:7.03-7.08x4.31mm
Depth:61.1%
Table:56.1%

HCA score: .9 (ex, ex, ex, vg)
Depth % 61.1
Table % 56.1
Crown Angle: 34.4
Pavilion Angle: 40.7

approx $8200

1k difference in price, the H&A is an I where the GIA Ideal is an F color, both score well on the HCA, and the GIA is .06 cts bigger

any thoughts??

Are both eye-clean?
 
I haven''t seen the 1.37 in person, the 1.31 is eye clean.
 
If the 1.37c is eye-clean I would go for that, else the 1.31c.

does this look like it will be eye clean?

Do you happen to know, or can u comment on, Mondera''s reputation?

Nope, never heard of them.

Anyway, you cannot judge if a stone is eye-clean from the report. It is only used to map out where the inclusions are, you have no idea of the intensity, color from the report. The best way is to ask the vendor about it.

Also, a thing to note in buy SI1 and lower clarity stones is to note the extra comments such as additional clouds not shown. These could be small, insignificant or very wide-spread but low intensity. The widespread kind could result in reduce optical performance by partially blocking light returns making the stone less lively even if it performs well on the HCA prediction.

This stone might have that characteristic. Do you trust the vendor enough to let them make that judgment for you?

Mondera have a good rep as far as I am aware, but don't have in house diamonds to the best of my knowledge.

SC, this is not true. Where it just says " clouds not shown" in the comments section of a grading report, it means they are a non issue and just mentioned for the sake of completeness. They will not have a negative impact on the diamond. If clouds were the grade maker then possibly they could have a negative effect and this would need checking for in this case as it would appear they are the grade makers, and if it said ' clarity is based on clouds which are not shown", but not if simply ' not shown' in the comments section.

So to summarize, clouds which are a grade setter could be an issue, with caution being needed with SI1 and SI2 particularly. " Clouds not shown" in the comments section, not an issue.

From John Pollard - "Not shown" means the characteristic was taken into consideration when assigning the grade but keeps the impression in perspective."

Then read this topic where Gary explains his point, which I believe makes sense.

Yes and I think you misunderstood, Garry is saying as I did that grade making clouds can be a problem in some clarities, not clouds not shown in the comments section, see here quoted from this thread from Garry.

"I should have qualified that "Clouds not shown" is a normal and frequent warning because it is impossible to represent a cloud on paper without over representing the cloud.


My other statements stay however. When the cloud is the grade maker I would never buy an SI stone and i would be very careful with a VS2 - if the cloud was near the culet it would be very bad."
And from Wink concerning clouds not shown and why Garry made the statements above.

- " While I would agree with you in the SI2 and I1 catagories that have cliouds setting the grade, I will have to respectfully dissagree with you on the above comment. I have seen way too many stones with the "additional clouds not shown" comment that were talking about such tiny clouds of pinpoints with NO affect on light performance to ever agree with such a blanket statement. If you are referring to the lower grades, then yes, I agree, but your statement makes it look as if you are warning people to avoid all stones with such a comment, which would relegate WAY TOO MANY wonderful stones to the "unsaleables" catagory."






 
This is an SI2, a lower grade. I am just warning him. It is up to him to decide if he will want to go on with that.

Remember the case, I forgot who, who bought a stone that was AGS0 but turns out darker? I remember it was an SI1 with additional clouds not shown comment.
 
For those reading if a cloud or clouds are grade setter, for example the reason that a diamond is an SI2 clarity grade, then this definitely warrants careful evaluation by a trusted vendor. Because the diamond above has clouds as the grade setters and it is an SI2 then it needs to be checked by an expert because of this. The remark in the comments section stating ' clouds not shown/ additional clouds not shown' is not of concern.

Clouds not shown/ additional clouds not shown in the comments section of a grading report of a diamond is considered to be a non issue, see the thread below also.
