Have you heard of a GAI appraisal? Can you tell me more about it?

Yes, use it as toilet tissue..

Dylasia will get you know where in this case RUN.

I would like to note that it is for multiple 14 pointers already set. How do I confirm the color, clarity and quality of cut (might not matter much at this size)?

My guess is that they probably exaggerated by at least 2 grade. How much is the the ring? what are the specs?

 

[nkc]

It's not a ring. I just would like to know, in general, how to confirm the color, clarity and quality of cut (might not matter much at this size) of 14-15 pointers if already set.

Clarity is done with a microscope or hand magnifier.
Color is done by comparison with master stones and a standardized lighting environment.
The easiest way to do cut is with a magnified reflector, like an idealscope or ASET.

Denverappraiser, Thank you so much for your reply. Is it possible to do that if they're already set?
The seller says thet're G-H color and VS clarity. He says he can see some arrows. What would be a good price per carat (they're 14 pointers)?

 

[denverappraiser]

Yes, you can grade stones mounted but it increases the margin of error for obvious reasons. Appraisers do it all the time.

Arrows have very little to do with it.

Pricing varies dramatically and I haven't seen the goods or researched the market. There are other variables, like craftsmanship of the piece and the nature of the store, that likely will have a bigger effect on price than most of what you're asking about by the way.

 

[denverappraiser]

You're apparently willing to rely on GAI and the seller for the grading but not the pricing. May I ask why? The seller has chosen them as their expert and you chose the seller in part based on this information. If you support that decision, go with them. If you don't support it, hire your own expert, do it yourself, or find a different seller. Picking and choosing which datapoints you like and which you don't is going to bite you. If you decide the seller is asking you to make a decision based on faulty information, don't just hold it against the 'appraiser', hold it against the seller who is asking you to rely on them.

Thank you so much... How and why would the nature of the store affect the price?
Are you located in NYC?

I'm not sure why the seller is choosing GAI? It could be because of location, or any other reason. I don't know anything about GAI. I have dealt with the seller once before but there's always the possibility that he might not know the quality of service that GAI provides.

 

[denverappraiser]

He knows. And, by the way, I don't. I've never heard of them before. The traditional reasons for choosing 'pre-sale' type appraisers aren't necessarily in your best interest but it's a good sign that you know and trust the seller. You're relying on the seller, not GAI. Anyone who wants to can hang up a single and call themselves a gem lab. The key is that you don't have to care what you think. The burden is on them to convince you that their opinions have merit and the default answer is no.
