GIA report with T&Co inscription

[Dede59]

Hi all,

I have been shown a diamond from a local jeweler and the GIA report shows an inscription from T&Co. Does this mean the diamond is second-hand? How else would a jeweler have access to a Tiffany diamond?

I’m very new to the diamond shopping experience so any other tips and helpful advice is welcome.

Thank you

"Used" diamonds are probably often sold as new.
Unless it was owned by someone famous its provenance is discarded; your jeweler may not have even been told it was "used" and had no way to know it did not come directly from a mine.

When someone dies or divorces they don't throw the diamonds away.
Those not kept by the family reenter the system.

Personally I don't mind.
They are already billions of years old and I'm not superstitious.

I believe they started laser inscribing the origin of diamonds. Never heard of just T&Co - anyone can do that rather inexpensively.
Here is a discussion

Tiffany laser inscription hidden under prong?

I'm looking at a second hand Tiffany six prong diamond ring. The seller isn't able to find a laser inscription on the diamond. Is it possible that the original Tiffany jeweler covered the inscription with a prong? I feel like that's something they would consciously try to avoid, but was just...

I’ve seen a stone with the Tiffany logo laser engraved. It’s been at least 10 years …. But I recall it was the stylized logo.
As Garry points out, laser engraving a diamond is relatively simple and cheap.
In the case of the stone I recall it was a boutique style cut……at the time I did believe the inscription to be legit.
None of this actually helps the OP to figure out what they’re looking at in relation to Tiffany.
What was the GIA grading for the stone?

Tiffany & Co stopped using GIA around a dozen (?) years ago and issue their own Diamond Certificate now. That said - back when they were using GIA - the girdle was inscribed "T&Co" or "Tiffany & Co."

It's not unusual for diamonds to change hands over the years. If the diamond was initially sold by Tiffany, with a GIA report, it would also have been accompanied by a Tiffany Valuation Letter and Tiffany documentation. Any chance those things were passed on to the local jeweler?

Great info John!!

From what I remember the inscribed logo was a stylized font- clearly associated with T&Co.....like a logo.
Not that it couldn't be faked......but it looked very nice

I don’t believe there is any t&co documentation, but I haven’t asked either. The GIA report is from Feb 2020 though..

Thank you, Gary. According to the GIA report are numbers also included in the inscription along with T&Co

The GIA report on this stone is dated Feb 2020, so it may seem that it was sold by T&Co years ago and got sent to a GIA lab for recertification in 2020?

I haven’t officially seen the T&Co inscription, I only noticed it on the GIA certificate of the stone.

The GIA grading is 0.84 H IF 3Exc None Fluor

That meets their color and clarity criteria. If you have the proportions I can tell you whether or not they fall into the cut criteria required by T&Co.

 

[Rockdiamond]

I agree with John.
Furthermore, it's highly unlikely someone would fake a stone like this....
In all likelihood, the diamond you're being offered was, at one time, sold by Tiffany.....

Hi John, thank you so much for your help. I have attached the image of proportions from the GIA report.

Is it possible to see when this diamond was originally sold through the T&Co serial number? I wasn’t able to find a serial lookup through T&Co website.

Should I even be concerned about this? Only reason I am concerned is because the jeweler seems to be skirting my question “is this a second-hand stone”. To which I wouldn’t mind if it was, as long as the price reflects that.

Those proportions are common for Tiffany, but not what I would choose.

May I ask why not?

I think its cut is quite deep. I would not go over 62 depth as you would lose a bit of the face up spread. Also fairly steep crown angle 35 plus fairly steep lower pavilion at 41 degrees may result in not best light return and possible light leakage. But I am not an expert, just my opinion.
