Help! Did I buy an OEC diamond with a fake GIA report?

Hi PSers - I need your help!

I’ve been on a hunt for an OEC to make into a pendant after seeing all of your wonderful post.

I found a deal on eBay that seemed too good to be true. A comparable (but new) stone is 4500+ on trusted vendors for the stone alone - e.g on old world diamonds.

Now I’m thinking the GIA report and inscription might be fake. I don’t have access to a gemologist right now due to COVID19.

Specs:
$2190 for diamond set in platinum prong and bunny ears (rabbit nail) pendant
Old European cut
.82 carat
H color
VVS2
GIA: https://www.gia.edu/report-check?reportno=5201900729
I did check the Gia laser inscription with a loupe but it’s hard to see. It looks like the right number.
Another concerning thing is the diamond is very bright - Looks higher than h to me!!!
This is the diamond next to my G color David Klass eternity ring.

eBay link of item I bought: https://www.ebay.com/itm/223911112276
Instagram link from jmjsjewelery (she uploaded these for me)
I did more sleuthing and this other listing from the seller looks weird. It’s listed as a round brilliant loose stone but it’s an OEC - Gia report classifies it as brilliant too: https://www.ebay.com/itm/223988192161
  1. My uploaded videos of pendant in different conditions

Is anyone doing man made with frosted/bruted girdles? I’m not sure but didn’t think so?
It looks like yours is?

Is your ring have any fluorescence? The pendant does, could that be what you are perceiving/ seeing, depending on the lighting you were in, especially if the ring stones don’t?

It is a pretty one!

I am not an expert, and hope the experts will come along soon to offer their advice.

However, please confirm if the so-called comparable stone in your original post is brand new or not.

Please bear in mind that new stones will always be more expensive than pre-owned ones.

I had sold jewellery pieces myself in the past via eBay at huge losses compared with what I paid for them originally.

As for the colour, it is needs to be a like for like comparison, as in size and cut, however, the experts will confirm if this is the case or not.

Personally, I believe you have begged yourself a bargain as the pendant looks nice to my untrained eyes.

What exactly makes you think the cert is fake? The colour? Or the other stone (which is a OEC). Did the vendor mix up the pictures?
Your stone looks very nice!

Hi Roselina - all the certs we’re done February 2020 from the seller and I saw another posting that looked strange that GIA graded it as brilliant cut with good cut when the picture is an OEC: https://www.ebay.com/itm/223988192161

For my stone that I bought, the color just seems very bright and glassy (vvs2?). All other searches and vendors I saw for these specs were 4500+ USD for a new stone with H and VVS2. And this stone was only 2190 with the platinum pendant setting on it.

the stone is listed as preowned and this is what the seller said when I asked why prices were so low.

“Hello again, I’m not sure where you are shopping but I mark my listings as wholesale price that is why my prices are the way they are.”
 
You say glassy... do you think the stone itself could be fake?

Yes I wonder if it’s just a simulant of some sort with a Gia report and fake laser inscription


it’s so much brighter compared to my diamond engagement ring and diamond eternity ring

Thanks @Rfisher! On the report it said medium blue fluorescence. I don’t have experience with flourescence at all so this is a good point!

Sorry, I was referring to the comparison stone that cost 4500+ in your original post, and you have confirmed my suspicion that it is a new stone in your other post.

Therefore, I believe I am right in saying that, like for like, one cannot compare the prices between a new and pre-owned stones, as a new one will always be more expensive.

I agree with this and dont think the price is crazy. I would be shocked to see a preowned H color OEC under 1ct sell for 4500.

Thanks for the verification @lovedogs @dk168 ! I’m new to the old european cut market and just saw that loose stones were very expensive on sites like jewels by grace, old world diamonds, ivy and rose, (all european old cuts are old stones right?) so compared to that it seemed like a bargain price and made me suspicious

Not all OECs are old stones. Not all are preowned. And there is no universally agreed upon definition for what makes a "good" OEC in terms of cut. It's all subjective so hard to compare stones directly since they have different "personalities " in terms of facet pattern. I think you got a good deal on a legit stone.

The price is good, but not unusual for the secondhand market. Do you have a UV light, to check if the stone indeed fluorescences?
 
(all european old cuts are old stones right?)
As the others have commented, it is a description of a type of cut, and it has no bearing on the age of the stone itself, as in one can have a precision cut stone of an old cut such as OEC and OMC as in Old Mine Cut.

One of the reasons your stone is not considered old european is that the table is too big. It is a pretty stone. There are several parameters GIA requires be met to classify a stone as a bonafide Old European stone. I have a K colored OEC and it does not look like it face up, has to do with the way the faceting is.
 
I've also seen what most would call oec or transitional makes with GIA certs that say round brilliant. that don't fit 'GIA classification' parameters.
I think you bought a nice secondary market pendant for a reasonable price which is getting harder to do!
 
You or a jeweler or an appraiser can match the stone to the report judging by its characteristics.

I would guess you are seeing the effect of fluorescence.

@DAF sorry for the confusion!

The stone & pendant I bought is classified by GIA as an old cut european for some reason even though the table is 57% and the cutoff is 53% by GIA standards according to this GIA standards link (https://www.gia.edu/gia-news-research-round-brilliant-cut-diamond-pay) - is that strange?

I linked another loose stone by the same seller that looks like an OEC but is classified by the GIA report as round brilliant - which I thought strange!

It just has to meet 3 of the 4 criteria to get Old European Designation, so the 57 table is not anything to be suspicious of. The other stones may have just missed the criteria, but still look like oec. Nothing suspicious. Also the price is in line for pre-owned. Based on your photos the table looks about 57%, which matches the report. Oec tend to face up whiter because the facets are bigger and can reflect bigger chunks of light, so what you're noticing is probably a mix between that and fluorescence.

@ForteKitty thank you so much for your knowledge and insight - I did not know this! That makes sense now why those two stones are classified that way.

@Rfisher I checked with a UV light today and it does have medium fluorescence like it says on the GIA report! I'm more reassured now, especially with the matching GIA inscription, table size, and dimensions and all of your comments.
