Diamond with H&A inscribed on it.

[discostu]

Looking at a GIA certified stone that has H&A on the report only because the cutter inscribed it on the stone. Am I wrong in thinking that I would be paying a premium for this when it is meaningless since it is not an actual H&A but the cutters opinion?

How have you determined that the stone does not display the H&A image?

Looked at it. It pretty much had the pattern of what I have seen as H&A but I can''t be 100% sure.

There are no enforced standards for H&A, but that doesn't mean the diamond you are looking at does not have a strong H&A pattern. If it has good proportions, top light return and exhibits a strong H&A pattern it can be considered H&A and may command a slight premium. A few important things to learn: Is the diamond a great performer? There is no reason to pay extra for H&A precision if it does not have top light return. What are the proportions and what are the finish grades? How did you view the optical symmetry (through a H&A viewer?).

Quality H&A diamonds usually fall within a proven range of measurements and are crafted well enough to earn high polish and symmetry grades.

Certain stones sell at a premium for the Hearts & Arrows patterns. How much of a premium is often negotiable. The point of looking for the pattern is that this is evidence that the stone has high precision cutting. Hopefully, this is coupled with good optics. Usually it does, but not always. They will generally defend this claim by presenting grading reports, Brilliancescope reports, Idealscope photos, Sarin models and the like to back up what they say. The writing on the girdle is mostly to help you recognize a particular stone and match it to the supporting documentation. On it''s own, seeing a good pattern in the scope doesn''t get you much more than something to talk about at parties. I suppose that''s worth something but I whouldn''t pay a whole bunch extra for it.
