Are you sure you didn’t get scammed by the seller o fthis diamond? Where did you get your gem from? I know there are some scams out there, so just want to make sure you didn’t get taken advantage of

 

If it is an authentic lab diamond, I would find a new jeweler. Lab diamonds are common enough and have been around for awhile. I wouldn’t trust someone working on my ring who does’nt know about it

Diamond Nexus drives me insane because they use the term “lab diamond” when what they actually mean is “diamond simulant”. Diamond hybrid is just marketing speak for diamond simulant. It’s so misleading and unfair. Diamond Nexus is NOT chemically, mechanically, or otherwise identical to a diamond. Lab diamonds are a real thing but they aren’t made by Diamond Nexus.

A true lab grown diamond can be mounted exactly like any other diamond because in every way it is identical to a diamond except the way it was grown. If you perform testing on it, it will appear exactly the same as a diamond- again, because it is one. This is the kind Brilliant Earth sells.

Diamond stimulants, such as the treated CZ “diamond Nexus” brand stone, CZ, and moissanite all have different physical properties. Testing can be done to see whether or not it is identical to a diamond because the lattice structure/chemical makeup of the stone is different, and lattice structure is what determines things such as hardness and reflectivity.

You should honestly be able to mount all diamond simulants same way as a regular diamond, but CZ is much more prone to scratching and chipping than most other simulants which are more prone to scratching than real diamonds. But if you’re careful with them it should be fine.  

The one thing I would warn is to make sure your jeweler doesn’t try to polish the stone at any point.

lilikoiheller : And if your jeweler looked with a loupe, it should be indistinguishable to a mined diamond. I’m glad you didn’t get scammed! I almost fell for diamond nexus’s advertising so just trying to help. 

I think you should find a new jeweler, though I’m not an expert about how jewelers set stones, i think you should work with one who’s familiar with your stone and its properties

12_Elle :  I just showed my husband your post because he bought my engagement ring from diamond nexus and I F’in hate that stone. I just wanted to dig at him again over his cheap buy, not that I need it anymore since we have inherited diamonds but thank you for explaining diamond nexus

KKJohnson :  haha glad to be of service! I mean I don’t really have an opinion on the quality of Diamond Nexus and I’m all for diamond simulants in general (science grown stuff is more romantic than dug out of the ground in my geeky mind). But the way that company advertises is so shady and underhanded that it really gets my hackles up. It’s like calling an ebook a paperback and then shrugging your shoulders and saying “haha, should have read the fine print!” when people get mad.

 

 

lilikoiheller :  If it’s a lab grown diamond it should be fine to polish because the structure will be the same throughout. Any diamond simulant (CZ/moissanite/Nexus) I would be much more hesitant about polishing because they are often made of a hard scratch-resistant shell protecting a softer/sparklier inside. Think of it like laminate flooring vs a hardwood that can be sanded and refinished. Realistically there’s no reason to polish any stone unless the jeweler accidentally scratches it during settings, but I’ve heard stories of Bees on here having their simulants ruined by polishing so it’s worth checking.

Can you tell the name of the seller or post your certification? Companies like Chatham and D.NEA and Pure Grown are legit lab-grown, chemically identical to earth-mined (although I hate that term, I mean where else would could they be mined from).

If it tests as a diamond with a thermal tester, then it’s lab grown.  Otherwise, it’s a coated cz, or a moissanite, or one of a hundred different types of sims. 

Mind you-any vendor can sell something and call it a lab grown diamond, and have it come with “paperwork”.  This is how the ebay vendors get away with selling cz’s as lab grown diamonds.

lilikoiheller :  I just ran the ID number on the IGI webpage and it came up as an error.. idk if there was a mistake but I would look into it. That would scare me a bit. I also just got a diamond that was graded by IGI and it’s cert looks totally different. They could be just different pamphlets from the same company, but I’d definitely look into that since the ID didn’t come up. Brilliant Earth is very reputable though so I’d be shocked if something shady is going on??

lilikoiheller :  just make sure that jeweler gives you the same diamond back.  My mother in law had a jeweler try to give her a different diamond then what she had.  Just be careful.  This was years ago years.

marriedalready69 :  you’re right sorry!! I ran it on their North/South American site and it didn’t come up probably because (like she said) she’s from a different country!

I was gonna say Brilliant Earth is crazy reputable I can’t imagine any fishy business going on
