Hi everyone,

How does SuperbCert and Engagement Rings Direct H&A diamonds compare to Good Old Gold. I know that GOG puts stones through all sorts of tests and that the diamonds are GIA Excellent and AGS Ideal (or estimated). Do SuperbCert and ERD have as good of a reputation? I have done searches on this site and both seem to get good reviews...I just want to know if they are equivalent to GOG.

Thanks in advance!
 
I''m not sure I understand the question, but you can get diamonds of equivalent quality from all three vendors. You just have to know what you are asking for and how to evaluate the diamond.
 
equivalent in which way?

Round stone quality case by case basis.
Princess quality - gog SuperbCert then ERD
Cushions it once was ERG then GOG but GOG has come on strong and is on top I think.
Asschers - gog rocks with video and Jon''s eye, if ERD figures out how to take good pictures they will be strong here. They find some good products.
Emerald cuts - ERD gains some ground there but gog is tough to beat with video.

As far as being trustworthy..
I would rank them: gog and erd are good with superbCert still proving themselves after some bad history with some PS members. so far so good.

As far as providing information:
gog then superbcert then erd(fix the photo setup)

Which criteria are you interested in?
 
I agree with Storm, depends what you are looking for. I bought an asscher and an oval from GOG. I have been very pleased with them.
 
Should say I was assuming round stone. And what I meant by equivalent was AGS 0 H&A would be easily sourced by all three, if that was your criteria. But Storm is right... it depends on what you want and what you mean by equivalent.
 
I would venture to say that price is a criteria too!
 
All the vendors you mention carry great stones.

But as other have said, it depends on what you''re looking for.

Off topic: I have the same pic as the one in your avatar. St. Lucia, Jalousie Beach, right?

amazing place.
 
GOG''s customer service is absolutely outstanding.
 

Thank you for your responses! I am actually looking for a round H&A diamond. I would like to find something that is both GIA Excellent and AGS Ideal (or estimated). I know that GOG provides both GIA and AGS (or estimated) scores. I would buy the stone from GOG, however, I find ERD prices to be a little better. If a stone is GIA Excellent, is there any way that Mark at ERD would be able to let me know if the diamond would also be estimated as AGS Ideal? Or is it only Jonathan at GOG that can do that?


elle_chris -- yes!! It''s a photo I took of Jalousie Beach in St. Lucia when my boyfriend and I were on a cruise. It''s a gorgeous beach!!

I just bought a stone from GOG this weekend. According to Jonathan, GOG leases the proprietary equipment that AGS uses to analyze the cut and has the software that goes with it. In that way, he is able to take diamonds that have been certified by GIA and provide "AGS-type" info for it. I hope that I explained that correctly.

I have no idea if ERD does this or if other vendors do this as well.

gog is the only one I know of using the AGS software combined with a scanner to give AGS approved AGS light performance scores with GIA graded diamonds.
