Question about uncerrted stones

[Dizzie]

I was just looking through Pricescope search and realized that even in the large stones 2.5 ct +, there are now and then uncerted ones. Considering that the cost of the certificate is rather marginal to cost of a 3-4 carat stone in a mid color/clarity range and uncerted stones are sold with the discount, why would vendors do this?
Is it solemnly driven by the attempt to sell a stone with an issues or do I oversee any relevant reasons.

Thank you

Are most of the larger uncerted stones you are seeing old cuts?
I think the value of the cert maybe somewhat diminished in that case.

I do see many private sellers with larger stones go through the grading process in order to get a better price and appeal to a wider range of buyers. Some jewelers clearly feel their in-house grading is sufficient and for many one-time buyers they will never learn about GIA, AGL, or EGL.

Maybe others will chime in as well.

Such a good question. I'm a newbie so I would love to know too...

I'm not sure what stones you are looking at, but all the uncerted stones I see are virtual stones being offered by one particular vendor. I have always just assumed that whatever list the vendor was pulling those stones from was missing cert data, or maybe the data is in a format that doesn't play nice with the Pricescope interface, or maybe whoever linked the list to the Pricescope database just made a typo.

Pick a couple of stones you're curious about and see if you can find a diamond with identical dimensions and stats being offered by another vendor. I bet it will have a cert.

At my jewelers, they sell uncertified studs, that were tempting for a while. They looked sparkly, but I didn't consider them seriously b/c I have anal mindclean issues with everything that won't let me spend that much on non-certified stones.

Why would they do it?

If you are talking about a modern cut stone owned by a store?

Then it is likely that if they certified the stone it would come back unfavorably in some respect.

If you are talking about a consignment stone or an old cut... then there may be other reasons.

I did almost buy an certified pear from GOG once. They were very honest about the stone though. So there are exceptions. I ultimately didn't like the tint (strong brown tint) and decided against it.

If it's an uncertified stone carried by one of the following vendors: GOG, BGD, Wink (HPD), Todd Gray, or WF, ERD, JA, JBEG (or whatever their 2 new stores are called)... I would just ask the vendor why. Because I would trust them to tell me the truth.

But not all vendors in the PS search engine are equal. And there are several I would not purchase from.

The stone could be newly cut and they have not sent it away yet, that happens with a number of reliable vendors on here. The stone could have been a trade-in or preloved and it never had a cert, in which case they might try and sell it first without one and then eventually get around to getting it certified.

Many old cuts and older preloved items do not come certified. People lose certificates or they never had them in the first place.

Vendors that make a habit of selling modern cut non certified stones also have the habit of mis-grading most of their stock. I would suggest this is to intentionally mislead their customers so that they can sell stones that would come back several GIA gradings lower in colour and clarity compared to their over inflated opinions or in some cases valuations that they write themselves. This should raise a red flag to any potential buyer.

This was my thought. It's easier to fib about what the stone is without a piece of paper telling a different tale.
