New Diamond - Old DQD

[sanek]

Hi All

I am in process of purchasing the following diamond but just realized that DQD has no light performance information. Report is dated March 27, 2007.

1. Should old DQD on the new diamond be of concern? I am concerned that I am paying AGS0 prices for diamond that might not qualify as such under new system.

2. If no concern, what are your thoughts on this diamond?

Ideal Scope?

Unfortunately I don''t have any Ideal Scope images. Should I stay away from it to be safe?

I''d stand by comments made in the linked thread. To be safe, particularly if paying AGS0 premium prices...I think you would search more broadly.

That confirms my thoughts.

One other question, would this be considered Class1A diamond?

The only thing out of range is pavillion depth (42.7%). Does it mean that I should check price as Class1A or Class1B diamond?

If a vendor cannot provide documentation, pictures, idealscope, and an asset I would be very leary of what I cannot see.

Unfortunately, as metrics being weighted goes...the pavilion counts the most.

Sounds like you want to go ahead. On cut...the variance for price, I think, is the softest among the 4 Cs. Maybe you''d find that the scoring for 1A can still work, per Dave''s rules, if only one metric is off. It did once score ideal top for AGS, and they''ve accepted it''s current score. There''s probably every reason to like it a lot, and it''s even possible mere mortals couldn''t easily distinguish from a different new AGS0.

I am sorry, I think I am a bit confused.

Can you please clarify whom are you referring to here (they''ve) ?
"It did once score ideal top for AGS, and they''ve accepted it''s current score."

I am certainly not convinced that it is the right stone. I simply want to understand how much should I be paying for.

Which is the proper link to determine fair price?

Starting fresh...your option is probably lovely, whether or not it makes newest AGS0 for light performance. Since it''s close to dead center in an HCA calculation (.5 TIC), just use this "search by cut" db price defibrillator instead...giving you a guess square, based on internet pricing, of $6K, give or take $1K. comparing to diamonds also scoring 0 - 2, between 1.15 - 1.25 carats, with the same clarity & color.

A significant problem with your second link is that, although you could choose to compare to either 1A or 1B (on Dave''s site he writes:
"1A grade:
All characteristics are best when 1A, but may include a single 1B characteristic. You pay a premium for this cut and you should insist on getting exactly what you are paying for."

....so, given the pavilion angle issue, you be the judge...

but the main problem is that a wide range of certificates are included, being a greater factor for price variability.

And...re your first link...sorry...I tried it and changed my mind...that''s a better link, providing lots more comparables and therefore detail, and treating Winks option as the correct outlier it is. So, make that $5500 approx, with a $1500 spread, plus or minus. Set up the same constraints as before, but this time, constrain for only AGS certificates.

Finally...

''It did once score ideal top for AGS, and they''ve accepted it''s current score.''

Probably this link will give the helpful background. AGS uses a newer system you''re aware of...but might only recently be not giving their highest grades to anything but those diamonds which show the 0 for light performance. In other words, AGS felt it appropriate to continue to lend their name & authority to certificates which still performed under their old system. So...maybe that is changing. Then again, who''s to say what they''ll give zero to in 2 years.

Meanwhile...although it''s hard not to get a controversial score on the HCA when it''s below 1 (sorry, go back to school on this if you want), and you''re best off if you can get reflector images of your option for further confirmation...if your diamond will come with a modest return policy, and you''re satisfied enough, how bad could it be?

Ideally, you''ll compare with others. That''s always best.

Warm regards,
