Would you consider a RB with a lot of twinning wisps if it was AGS 000?

Danny- I tried doing a search for graining and clouds but of course now I can''t find anything. From what I remember, it ''can'' cause transparency issues in SI stones.

Hi elle,

What''s graining (surface lines?). Sorry for the dumb question.

Danny

Irregularities in crystal growth. It can look like polish lines, it can look whitish and it "may" give the stone a hazy appearance.

I don''t know anything about twining wisps, but the pics of the diamonds with them look beautiful to me. I saw clouds were also mentioned as a no-no, and I have an AGS 0 diamond that is graded SI2 with clouds, and I don''t see that it looks any less brilliant. In fact it''s a fireball of a stone. So, maybe clarity effects are exaggerated in some cases.

After reading this site for the last few years and trying to learn as much as i possibly can about stones, all I want to add is this- When you get down to an SI2 clarity there''s always going to be something, or someone, that''s going to say it MAY effect the brilliance in negative way.

1. Clouds can cause loss of brilliance, 2. Feathers can have durability issues, 3. Black inclusions will be eye visable. 4 Clouds and graining a big no no, and now 5. Twining wisps can reduce light performance.


It''s an SI2. There will be inclusions and chances are they will have at least some of the above.


I have never, ever seen a professional come here and say it''s a safe choice. My opinion is either buy from a trusted vendor, or/and have it appraised by a trusted appraiser. That''s really the only way you''ll be able to set your mind at ease.


Btw, the pic is obviously an H&A stone so I''m thinking it''s in house from one of these vendors. If they''re saying there aren''t any problems, I''d trust them and have it shipped to appraiser of my choice.

I would agree that si is where you start making compromises for the money you save.
But as long as those compromises are not eye visible and have no eye visible impact on the light return or durability issues they are excellent values.
A trusted and knowledgeable vendor used to dealing with high performance diamonds is critical.

I agree...

Personally, I think in MANY cases. As I keep saying, buy diamonds with your eyes. It is nice to know what is in the diam ond, as much for telling that it is yours, but often you will be given wrong reasons to fear the diamond when your eyes say it is wonderful.

David GIA acknowledges SI1 and down has potential reduction in light performance. They have published this.

It''s also true that a VS1 can have an imperfection which is visible naked eye- but in general, that would not be the case.
I feel the same way about twining wisps.
They can cause loss of brilliance, but my experience is that it''s very rare in a GIA graded SI stone

A rare problem for a diamond dealer is not much of a problem at all compared to a one off majaor purchase for a blind buying consumer.

If labs really wanted to provide consumer confidence they would start again with grading services.

How many diamontaires would buy a loved one a diamond based only on a grading report?

Garry- I agree- buying a diamond, blind, based solely on a GIA or AGS report does not make a lot of sense to me.
Buying from a trusted dealer, who''s looking at an SI2 diamond with twining wisps, and telling the consumer it is, in fact, eye clean, is a different story altogether.

As has been stated- when trying to buy based only on a lab report, it makes no sense to look at Si2 diamonds.
Trying to buy the best diamond for the money, for many buyers, neccesitates including SI2 in the shopping list- but not for those buying based only on a report.
