Your feedback on this particular diamond (GIA cert)...

[pranks]

Hiya folks! I plan to pop the question to my girlfriend next month - that being said - I have recently started looking into buying a beautiful engagement ring. After many hours (days) of research, I have decided to only go with GIA certified diamonds. Currently I am dealing with a diamond broker who will be showing me this particular diamond along with other diamonds this coming weekend. I am no expert and it is my first time buying a diamond ring... or a diamond for that matter .. I would greatly appreciate your feedback.

hmm.. interesting.. no one seems to help me out here...

Please folks - my appointment is tomorrow. Experts your thoughts will be truly be helpful to make my final decision. I have seen many stones with different wholesalers, retailers and now a broker. Since I am no expert - all of the stones looked beautiful to me but just having a hard time picking the most brilliant one.

My diamond broker insists that this particular stone won't be disappointing. I just want to confirm

Thanks again,

P

It's hard to say how the stone will look because GIA Ex covers a considerable range. When I punch the angles into the HCA Tool (https://www.pricescope.com/tools/hca) it gives a score of 1.1, which is excellent, and is within what it calls the "Brilliant Ideal Cut" range. This means that the stone will have excellent return of white light but may not have quite the "fire" or sparkle in lower light that some diamonds have - although it should have excellent fire.

You need to gather more information to evaluate the stone. The most important thing is to look at it, and be sure to look at in in all lighting conditions and from all angles. In particular I would look for inclusions; an SI1 stone should be eyeclean from the top but not all are. You should also consider asking for idealscope or ASET images of the stone to fully evaluate symmetry and light return.

I am not as expert as some of the other posters here on searching for the best deal online, but I did a quick search on James Allen and it looks like you might be able to get an equivalent stone for about $500 less, if you're willing to buy online. For example:

http://www.jamesallen.com/diamonds/E-SI2-Ideal-Cut-Round-Diamond-1450975.asp

That said, based on numbers alone it sounds like a fine diamond.

Do you have a Jareds near by? If so, you should go look at their Peerless line of diamonds before you go to your
appointment. That way you will have a good idea what a well cut stone should look like (for comparisons sake).

Also, look at the stone in all different lighting conditions to make sure it is eye-clean to you. Take it outside and any other
place they will let you go (they'll usually go with you).

Edit - not sure but this stone may fall into the 60/60 range (60% table, 60% depth). You can find some info here.

Thank you for your tips guys and I will definitely have the diamond looked at different lighting conditions.

@chriEs - I know this particular diamond got an "excellent" grade on HCA compared to the other diamonds that you have posted here from Jamesallen.com that got 2.5 rating.(maybe why $500 more expensive?) But, I am confused at your statement "this means that the stone will have excellent return of white light but may not have quite the "fire" or sparkle in lower light that some diamonds have."

My main concern is how would I confirm that the diamond I will be seeing is an actual GIA certified diamond? What I mean is that he can bring me a GIA certificate stating the diamonds specs but show me a diamond that is certified from an unknown lab..

I am dealing with diamond broker and not a retailer that is why I have this concern.

Thanks

Regarding the HCA outputs, I suggest you read this page: http://www.diamond-cut.com.au/
And particularly: http://www.diamond-cut.com.au/23_bicfic.htm

As for being sold a fake diamond, if there's a certificate you shouldn't worry too much about that. Stones can be switched, but I believe that doing so is criminal fraud: the possible repercussions far outweigh the profit from one (or even many) such sales. (Caveat: this is not legal advice, if you suspect fraud you should contact an attorney or law enforcement agency in the appropriate jurisdiction.)

But if you want to be absolutely sure, "GIA 2126810450" ought to be laser-inscribed on the stone; I imagine that the seller ought to be willing to show you the inscription under a microscope.

Edit:
Moreover, you should receive the original GIA certificate with the stone, meaning that even if the seller switched stones he would then be without the certificate and unable to claim that the real diamond was GIA certified. It's not going to happen to you. Conversely, if the seller won't give you the original certificate, run screaming.

i wouldn't buy a stone with 13% crown height. this is a flat top stone.

Like I said, the OP needs to examine the stone from all angles and in all light. Might be that he doesn't mind flatter stones.
