The experts here will give you their analysis on the data in the certificate, however I’m surprised you would consider the GIA VG grades rather than asking the vendor to only see GIA 3X within the parameters you’ve specified. If cut is your top priority, a GIA VG cut grade is not the best starting point.
In this case the VG cut grade is actually due to girdle being “very thin” - not a statement of poor proportions. These sorts of stones can (keyword - can!) be fantastic value if they’re priced commensurately lower than similar GIA EXs
thank you all for your kind replies . I had the gemologist sitting with me ( South African guy who really seemed to know his stuff ) I viewed the ring in the shop through a loop( is that what it’s called?) and outside in the street snd also went on Stone algo and that rated it 8.9 for cut? I’m so confused now as the diamond looked so sparkly and fire was amazing .. I did mention I was worried about the girdle snd they said they deemed it safe? It’s up for £1000 less than the triple excellent diamond …why would the cut be deemed better online than the triple excellent if ot isn’t? Like I say I’m not an expert but I thought I could trust the gemologist?
It’s confusing. It’s not just you.…why would the cut be deemed better online than the triple excellent if ot isn’t?
It’s confusing. It’s not just you.
GIA has a range of proportions that it calls EX. And a range of proportions that it calls VG. And a range it calls Good.
The range of proportions that it calls EX include stones that are #verybeautiful, #beautiful, and #notsobeautiful. of the EX stones will be #verybeautiful and #beautiful, and a few will be #notsobeautiful.
The range of proportions that it calls VG also includes stones that are #verybeautiful, #beautiful, and #notsobeautiful. Most of the VG stones will be #notsobeautiful and a few will be beautiful, and a very small number will be #verybeautiful.
Your EX is one of the few EXs that is #notsobeautiful. And this new VG option is one of the rarities that is either #beautiful or #verybeautiful (we can’t tell anything from those photos - too blurry and far away).
There are a number of proportion factors that are considered in these cut grades. Some influence the diamond’s appearance more than others. A “very thin” girdle is one of those factors that will downgrade overall cut grade (a “thin” girdle would have qualified for EX) but doesn’t by itself have much influence on the diamond’s appearance.

These any better ? They have told me to take it home wear it for a few days and if I have any problems to call them and go back .. it seems to sparkle and shimmer beautifully .. it was darker in my car but think that is a reflection of the ceiling in my car as it is all black including the ceiling .. the loop showed it as eye clean and I could not see any chips or scratches? But is that because I don’t know what to look for?
Do NOT take it home and try it for a few days. This is a recipe for disaster, given your current situation.
Again, did you read @MillieLou’s and my posts??
The stone may very well be DAMAGED right now. You have no idea what current condition is. But I GUARANTEE that if you take it home, decide against it, and bring it back, they’ll inspect it closely and any damage they find will be YOUR LIABILITY.
You need an updated report or independent appraisal BEFORE you take possession of this stone/ring in any capacity, temporary or permanent.
1000000% agree. I have a million concerns about this stone, and taking it home is a very bad idea
So why a million concerns? Thought proportions weren’t to bad and were better than the first ? Is a very thin girdle horrendously bad and could get damaged that easily? Wouldn’t I see any damage in the pictures and loupe? This is all getting me extremely anxious now ! Are the pictures that bad?
Also, If you are able to get your money back and start again I would do that.
@bananahead please don't be upset. This all sounds quite standard for the UK. Chances are these are honest people who want you to be happy and aren't trying to scam you.
The issue is that knowledge of well-cut diamonds is, in general, atrocious in the UK. The US is very far ahead. The jewellers probably genuinely think that both of these are good quality diamonds as they are GIA certified and are relatively high colour and clarity, and have very good / excellent cut. If you go to 99% of jewellers in the UK you will walk out with a badly cut stone, no matter how good their intentions.
There are some jewellers eg Durham Rose which carries diamonds which are an exception to this rule. You can also buy from reputable online US sellers like , or if you want the convenience of all taxes etc sorted for you and easier returns etc, with the help of Pricescopers you can pick a nice stone from eg (but get help with this). The link I showed you is an example of what you could get for your money.
It's worth asking if you can apply the deposit to something else (a credit for the ring setting, a necklace / earrings etc) and starting afresh with the diamond search. You may end up financially ahead as you can get a better diamond for less than you're paying. You could also ask if they are able to call in diamonds with the parameters you give them, or that you find online, for a fee.
Personally I would take the ring back and ask the question. But ultimately it's your ring and if you are happy with it, IMHO you will still have a better cut diamond than the great majority of people in the UK.
Yes, VTN girdle with a 10 yrs old report....So why a million concerns? Thought proportions weren’t to bad and were better than the first ? Is a very thin girdle horrendously bad and could get damaged that easily? Wouldn’t I see any damage in the pictures and loupe? This is all getting me extremely anxious now ! Are the pictures that bad?
