Hello, I am new here and this is my first post, so bear with me. I am buying a used diamond, and looking for a little advice. I basically have two questions, bolded below for easy reading since I am probably unnecessarily verbose (first diamond, nervous and babbly, etc).
The first is on the diamond itself. This is the GIA report:
Round Brilliant
Measurements: 6.17 - 6.20 x 3.86 mm
Carat Weight: 0.90 carat
Color Grade: F
Clarity Grade: SI1
Cut Grade: Very Good
Proportions:
Depth: 62.4%
Table: 56%
Crown Angle: 35.5°
Crown Height: 16.0%
Pavilion Angle: 40.8°
Pavilion Depth: 43.0%
Star length: 50%
Lower Half: 80%
Girdle: Medium to Slightly Thick, Faceted
Culet: None
Finish:
Polish: Good
Symmetry: Very Good
Fluorescence: None
It is currently set in an 18k gold setting with .50 carats of baguettes, but I'm not certain the girlfriend will like the setting, so we may have the stone set in a different setting. She will make the call when we go see it, but we are buying the whole ring regardless. Is $4,250 an acceptable price for that diamond and the setting? If tastes matter at all, she is most concerned with sparkle, so the cut grade was the only thing that I was iffy on. From my research I know GIA won't give an ideal cut rating if polish is only good, but all the other characteristics are within the bounds of an ideal cut. I've read online that polish does not affect the sparkle of a stone that much unless it is fair or poor, though, so I thought it might be a good stone. Is that true, not true, or is it just something we have to see in person?
Speaking of in person, that gets at my second question. The stone, as I mentioned, has a GIA cert, but I obviously want to make sure the ring I'm getting has the same stone in it as the one on the cert. I was planning on meeting at a neutral jeweler's to have them verify the stone. Do I have to go to a special appraiser or someone with special credentials, or since it's already certified can I just go to any diamontologist at any jewelery store (this will be in Philadelphia, btw)? Is this an expensive process on the order of an appraisal, or is this just a glance under a loupe and a, "Yup, on your way, sir"? Basically, I'm looking for advice on how to actually transact the purchase of a used diamond, while being as paranoid as possible. I have no reason to be, in fact he seems to want to cover his bases as much as I do, suggesting we meet at a bank to perform the transaction. I just want to be as cautious as possible, just to be on the safe side.
Anyway, thanks in advance for your help. This site is a great resource - I was pumped when I found it!
