The process of "verification" for a consumer almost never stops at the point where the diamond is said to be correct. In almost every case we are then asked about how well the customer bought the stone. What were the financial considerations? Now, that is another task and not at all a part of verification.
We used to offer a simple verification service and found that consumers were totally angered at our unwillingness to do more. It was clear to me that what was really wanted by the vast majority was a complete service with absolutely zero extras. That's why we verify, create an AGA-CERT with a cut grade, and do a retail appraisal on the stone while including a final appraisal on the finished item of jewelry when the piece has been completed. We spend the necessary time to discuss what a fair price might be and answer all the questions people want to know about thier major purchase.
We are glad to "verify" a diamond matches for a small sum, but I doubt many would truly let the flow of information available come to a stop at that point. This has been our experience over thousands of stones and clients. There are always exceptional cases and I never say we refuse to help people. It just would be most unusual....
The full service is $125. Verification alone is just $35.
Verification is a one sentence result which states we examined the diamond presented and that we are satisfied that it matches, or does not match, the document. We give no advice or further details.... If that would make you or others happy, no problem. We just have found it does not.
