Can someone tell me a little bit about this 1.64ct RB from GOG?

[lakai]

Hi,

I''m looking for some opinions about this stone. I''ve been looking around for a few months now and I keep coming back to look at this stone which has been in their inventory for quite a while now. Just looking for a little input about the it also wondering why no one seems to be interested in it considering stones with similar specs are usually gone pretty fast. Is it the price ? the color ? any opinions would be apppreciated.

I''d say, it''s been waiting for you.

Great color/clarity combo, great size, and very tightly cut. It''s an Isee2, and should be stunning. I say snatch it up!


But do put it on hold if you want to think about it.

It does look fantastic in the pics but I''m worried about those streaks of orange and blue. I''ve been going back and fourth on this stone for literally 2 months and surprised to why they haven''t been able to move it. Also the certs from 2006 and I''m really wondering why this stone hasn''t found an owner for 2 years.

I am sure the yellow and blue is just a reflection or a result of the photography, but ask Jon from GOG, he will be completely honest with you. Sometimes diamonds just take a while to find a home, it appears to be a gorgeous diamond, and I remember it from before - I think you were considering it.

I did have and from the face down view I can see the blue streak in the picture.

Ditto. Give Jon a call and ask whatever you want. You won''t find out anything just wondering about it.

Why

 

[swingirl]

That''s a beautiful stone!! For many people it''s in their fantasy range but not price range. If you are lucky enough to be looking for this size it''s a nice choice! Optical Symmetry--Superior! That is better than Ideal (I believe).

 

[LGK]

It''s a beautiful stone. Sometimes it just happens that a stone sticks around for a bit, they''re a big purchase for most people- it''s gorgeous though, and an Isee2 is going to be a sparkle bomb. And the color & clarity are a lot of people''s sweet spot, it''s common for VS2s to be eyeclean even from the side, which for a lot of people is a must. And H is still very, very white- personally, I can''t see *any* color in a well cut H that''s set and not sitting right next to a D.

Truly, those colored facets in the pic are not anything. Just reflection of whatever is around it. Maybe the photographer was wearing blue pants and an orange shirt? Or something like that...

If you want to talk about it with GOG I hear their customer service is typically excellent.

 

[kcoursolle]

Beautiful stone, I don''t have any reservations! Those streaks are more due to photography and equipment than anything else. I wouldn''t worry about it.

 

[strmrdr]

I''d buy it.
The angle combo is great.
Its tight and the optical symmetry is sweet.
It is cut to one of my favorite combos for a RB.
There is no rhyme nor reason sometimes as to why a diamond stays in stock or doesn''t a lot of the time.

Sometimes diamonds don''t sell fast because they have a lucky grade.
Like a VVS on the cert with an inclusion that you immediately see with a 10x loupe or an obvious yellow "I"...

Jonathan wrote, on his website:
"It is my consistent finding in diamonds with upper girdle angles over 45° that it reduces both light return and contrast within the diamond and has the most negative impact upon the diamond in terms of it''s cut quality."

The diamond you linked has an average upper girdle angle of 43.03°, but the upper girdle goes from 41.81° to ... 45.54° (that''s higher than 45°).
1) 3.73° difference, you wouldn''t accept it for the crown angle, so why would you for the upper girdle?
2) you can see the imperfection of the upper girdle in the DiamXray picture (look at the gray place).
3) the hearts aren''t all the same.

Still a nice diamond, but isn''t worth a premium.

Why do you have to mail to look at the AGS report?
Other diamonds have their certificate online.
Is it an old AGS cert (before June 2005)?

Garry warned you that you were going into the deep end without a lifeboat...
Which one of the 8 gray areas are you talking about and what causes them?

 

[lakai]

Face Down

 

[lakai]

Top view.

 

[strmrdr]

Hint here is the IS based on the numbers your worried about in the helium report.

 

[lakai]

Theres were the 4 stones I was considering. the stones vary from E G and H color VS2-VS1. Out of respect for GOG, I won''t point out which is which and what sizes are, but this stone is one of these.

I apologize to GOG if there is a problem with me posting these pics. Please let me know and I will take them down.

thanks

Look at this page where Jonathan also says that too steep upper girdle can cause white, pale white and weak redish areas between the arrow tips.
I'm sorry if I called it gray, but that is how it looks to me.

Find it in the IS or the ASET.

The report is from 2006. isee report says 11/2005 production date in, 1/2006 production date out.

I am also curious as to why I had to email for the report. This is the only diamond they have ad where the report needed to be requested. For this reason I am looking for other opinions. I understand that there are some opinions held back due to not wanting for them to lose this sale, but I am going to purchase a diamond from GOG that is within the same price range should I decide to buy this one in particular so please get as technical as possible. It''s hard to get opinions like this from favored forum vendors.

Thanks

Because the cutter said so.
Some cutters only let the stones be posted online if the report is hidden either because of the trade name in the inscription or the report number can be traced back to them and they don't want to be hassled like they were a few years ago.

Easy, same position.
Even if the other upper girdle facets also look pale/weak red.

Karl, would you call this diamond H&A?
Did you look at the hearts?

[Fly Girl]

In looking at the helium report, under the girdle thickness graph, there is a very low peak at about 112.5%. Could that be causing the steeper slope that Stephan is pointing out?

 

[strmrdr]

QM sorta like this one?
Its well under 45.. what your seeing is lighting related it would not surprise me that the 45 facets are at the bottom of the image you posted.
Rotating the diamond would make you pick a different set.

Not a problem at all lakai. We encourage input.

Hi Queenmum,

In answer to your comments about the upper half angles and my article on the minor facets, this would apply if all 16 of the upper half facets were cut >45 degrees. The fact of the matter is that there are only 2 that are as noted via the Helium Report which shows all 16 upper half measurements. You also correctly identified through the only technology available that shows that minutia of detail.

What does this mean?

Rest assured it does not impact the diamond''s optics or beaty one iota as it is nothing you would see in a visual examination. We walked in with that information and we are happy to provide it. BTW upper half angles are altered when there exists either painting or digging to certain extremities and the Helium Report shows us precisely how much this has occurred in any given diamond. If this diamond failed to meet the most conservative''s labs thresholds for painting or digging it would not be in my inventory and I would not have had my staff take the time to publish all of the material. It''s precision of cut combined with its optics put it in what is the rarest category for round brilliant cut diamonds on the market which is why I personally back it witih full lifetime policies.

Peace,

No that is under where the 43.49 and 43.7 meet.

The next set lower than you outlined with the 2 green peaks is the 45 set.
