re: Lab grown diamonds

If we are considering a loupe specialized equipment, then we are having a very different discussion. Nobody has argued you can tell the difference with the naked eye. A skilled jeweler can absolutely use a high mag loupe to spot growth pattern differences.

Yes you can
There are many ways a layperson can distinguish CZ from diamond (lab or mined) without any equipment at all.

I'm going off what the GIA claims.

I’ve got no idea, but this sounds like something a jeweler would say to try to keep the value of “real” diamonds up while in reality if you gave them a randomized test they’d do horrible

Since you didn’t provide a link, did they include what specialized equipment they include and which ones a skilled jeweler doesn’t have common access to? Otherwise it is fairly irrelevant of a point, since again, nobody is arguing the naked eye can tell.

I’ve argued for lab grown multiple times in here, just pointing out it is silly to say they can’t be told apart. And let’s be honest, you line up a bunch of random natural diamonds, you’ll get a bunch of different ratings on them from a group of jewelers too.
ETA: can also make the argument that lab grown ones are too good. While obviously wouldn’t be a 100% definitive answer, if everything is too perfect on the diamond, a jewelry would probably be going out on a pretty sturdy limb to say it was lab grown lol.

I'm assuming GIA's definition of "traditional gemological observations" includes a using a loupe.

You can have a 2.5 carat lab grown that is almost perfect or a mined 1.2 carat with imperfections for same price
Eh, I'm old, so when I think of a "lab grown" diamond I definitely think of a CZ. And I do realize the game has changed significantly, but it's going to take some adjusting for me to unlearn everything I know about diamonds.
My issue is that beautiful diamonds are generally considered to be rare and valuable (I know all about deBeers, just talking in generalities), and that the value has typically been obvious to the naked eye by utilizing the 4C's. When you look at enough of them, you can tell.
This crop of young women just want them big and clear. So every newly engaged girl has a colorless and internally flawless 3 carat, which is just laughable. It's truly what gives it away. A natural diamond like that in a setting with a wedding band is upwards of $50k.

Who honestly gives AF if it is real or not. Will she be thought less of by others if it’s found to be lab grown? Does she care that much of what others think about her lab grown diamond?
Go order a fake arse ring off Amazon, I did that for my wife to replace her tiny 1 carat ring I bought when we were 20 and broke AF. She gives 2 shits it’s a fake and people compliment her all the time. She says thanks and looks at me and says if they only knew and laughs.

A fake Rolex does not do that for a watch.
Maybe an edge case but yes in that scenario it would be the same watch just produced illegally.

I should clarify, people looking at someone’s ring in passing, say at a party, would never be able to tell.
Bottom line, any jeweler worth a crap isn’t getting fooled by a lab diamond. There are multiple markets..
CZ, no resale
Moissanite, minimal to no resale.
Lab grown diamonds, minimal resale
Natural diamonds, resale value.
If there was no way to tell, the diamond market would collapse.
Anyone can justify buying a CZ, Moissanite, lab or natural diamond.
The guy buying CZ thinks the guy paying more for Moissanite is stupid, as does the Moissanite buyer think the lab diamond buyer is dumb for paying more, and from this thread, the lab grown fans think the real diamond buyers are stupid.
Let say D, IF @ 1carat listed retail price
CZ @ $50
Moissanite @ $300
Lab grown diamond $2200
Natural diamond $10,000
These prices wouldn’t be where they are if not for the differences that can be seen or tested for. None are the same.

The GIA also says that looking for inclusions is a way a trained jeweler can spot a lab vs natural, which can be done with a loupe. Growth patterns can be seen with a high mag loupe. That isn’t 100% definitive proof, but I never said it was. I very plainly in the first post said that generally specialized equipment was needed, but sometimes it isn’t. Hell, even a lot of the specialized equipment is mainly just looking for imperfections and isn’t truly 100% by itself.
If that is a sticking point to you, go for it

I don't get the argument. If it's a diamond, it's a diamond.

Mine wife insisted on a mined diamond so I made sure to get one that was smuggled out of the deBeers mine shoved up a malnourished slaves arse and sold to a black market dealer for a years wages ($13).

She's gonna have it appraised in 2 days after getting it.

If a woman has a preference of real vs lab grown diamond she’s definitely not the one. At least not for me.
Let me guess…. She’d also probably prefer him to not drive a fun car or hangout with his friends?

I’ve tried. My point is since it’s just vanity, why not buy a CZ? Why buy a “diamond” at all since it just for show?

Unless a gemologist is using specialized equipment or the stone has laser inscription and they check the cert, it’s not possible to look at a diamond and tell if it’s lab grown or mined.
Oh yes they can tell. A competent jeweler can absolutely tell if there are no inclusions in a diamond, which is suspicious af if it's large and the person bringing it in isn't an OT baller.
