Despite all of their claims about being a "perfect man-made diamond", Diamond Nexus labs was revealed to be ordinary cz in independent gemological testing by the International School of Gemology.

They have posted their full review on their website here:
http://www.yourgemologist.com/DiamondNexusLabs.html

Update - this is an old thread, but the summary is DNL sued Intl School of Gemology to force them to take it down. Not wanting to pay the legal bills for fighting it, they removed.

However, a helpful email I received yesterday pointed out that archive.org still has the original report...so here you go:

If you are up for scrutiny, you need to be able to back up your claims.

Robert is a good, non-biased, reference for authenticity.

Re: Diamond Nexus fails independent gemological re

I was going to purchase from DNL until I found BTD!

It is interesting to me that a couple of my friends have been complaining because their email accounts are being inundated with DNL email advertisments!

So what's going to happen to their company? Is this just considered false advertisment?

It is outright fraud, but good luck getting any one to do anything about it...

Re: Diamond Nexus fails independent gemological re

It IS outright fraud. But what it really highlights are the problems with ecommerce. If these guys were just ripping people off locally, someone could contact the news and the police, probably rally together enough disgruntled customers, and put them out of business. They could be fined and possibly do some jail time.

But since they are ripping people off over the country, one person in Cali, another in New Jersey, another in Texas, what recourse are these people left with? None. They can contact the local police dep't, but they aren't going to act, especially if you live out of state and you are disputing $500.

I'm not sure how many people they are ripping off, but I can see the profit margin and it is VERY large. They advertise like crazy under hot key terms such as Moissanite and they nearly always rank near the top which can cost as much as $2 to $3 a click. If they can do that, and possibly be forking out $500 - $1000 a day in advertising, you know they are scamming many, many people.

RussianBrilliants.net is another that forks out mega $$$ for advertising. They don't make the same outlandish claims that DNL does, but after reading their FAQ for 30 seconds, you can tell they are trying to play the same game (i.e. sell CZ as a synth diamond). If you click on one of their loose stone pages, under the add to cart button, they call their stones 'Russian Brilliant Cultivated Diamonds.' These guys are 'proud members of the BBB.' Maybe its time someone gave the BBB a phone call about them too.

Re: Diamond Nexus fails independent gemological re

It looks like word is getting out to some degree. By doing a quick google of Diamond Nexus Labs (even without the quotes), it doesn't look so good for the company.

http://www.google.com/search?client=fire...G=Google+Search

Several forums popup near the top saying BEWARE!

I know people are still fooled everyday, but at least thanks to the International School of Gemology, answers do exist (ranked 4 on google). You just have to look a little bit.

Re: Diamond Nexus fails independent gemological re

It's about time! I found their site last year when I was researching Moissanite. I hated the way they dissed Moissy, and after 45 or so more minutes of reading the site, I found 'ZrO2', and knew wot they were really selling. Oh, the site was the first thing that came up under the Google search for 'Moissanite'.

Re: Diamond Nexus fails independent gemological re

from DNL website:
http://diamondnexuslabs.com/jewelry/information/faq.htm

Has the elements in Diamond Nexus Labs' gem material been verified by independent laboratory testing?
<br>
Yes, Diamond Nexus Labs has engaged three independent laboratories to confirm what chemical elements are present in our diamond simulants. DNL has chosen independent element analysis because the chemical elements found in DNL jewels are the basic building blocks. Independent testing means that the findings were verified by laboratory technicians outside the control of DNL. A chemical element, also called element, is any substance that cannot be decomposed into simpler substances by ordinary chemical processes, a substance composed of atoms having an identical number of protons in each nucleus. Elements are the fundamental materials of which all matter is composed.
<br>
Diamond Nexus Labs has learned there is some speculation about the atomic components or structure of its gem material, coming primarily from those claiming to be jewelers or gemologists, often misinforming others. Upon investigation, it did not surprise DNL to learn that not only were these so call "experts" not qualified as material engineers or scientists, but that they have not subjected a single DNL gemstone to the rigors of X-ray Fluorescence Spectrometry to actually make any bona fide statements with respect to the elemental composition of DNL's gem material , and most have never even seen a DNL gemstone. Clearly, unsubstantiated misinformation is always the product of those with their own agenda. DNL's independent laboratory testing was intended to put misconceptions to rest with results that meet the most stringent independent standards.
<br>
The elements in Diamond Nexus Labs' gem material in order of atomic weights are: C (6), O (8), S (16), Fe (26), Co (27), Ni (28), Y (39), Zr (40), and Hf (72). These finding have been reported and verified by independent laboratory testing with three separate independent laboratories.

Would someone please email this co and ask to see these 3 independent reports (please post their response)?

They are claiming Carbon, Oxygen, Sulfur, Iron, Cobalt, Nickel, Ytrium, Zirconium, and Hafnium in their stones.

In my opinion, the reality will be Zirconium, Ytrium, Oxygen and maybe Hafnium....in otherwords, a CZ formula.

We are going to be sending off some Asha samples with different thicknesses of amorphous diamond coating/infusion to a lab to further prove our coating (we will publish the results) as well as for some of our own research...and while we are taking the trouble to do this, we thought it might be interesting to test a diamond nexus stone via XPS (xray photoelectron spectrometry) and settle their claim above once and for all (they are claiming Carbon in their stone, and they complain no one is doing Xray spectroscopy...but we will <img src="http://talk.jewelry/styles/default/xenforo/smilies/graemlins/default/smile.gif" alt="" />.

Re: Diamond Nexus fails independent gemological re

My fiance purchased 1.5 ct from the site and it was the most gorgeous thing to ever grace my finger... NOT!

First off, they go around to random diamond forums, having their staff pose as actual happy customers, why would you do this if you have a good product, that sounds too good to be true? All of their info on their website is actually other sites that are talking about their CZ product as a plus. When plagiarizing, they forget to leave out the part is actually talking about the stone being a CZ!!!!

Sorry to spout off on the subject, it was just very upsetting when I starting looking at the stone, and realizing how fake and shallow it looked.

Anyway, my fiance threatened to report them to the BBB, and they were more than happy to give a refund for the ring and all of the shipping charges.

There's nothing wrong with CZ, but at least own up to what you're selling. Poor guys like my fiance would have never known, and I would've been stuck with a dud.

Re: Diamond Nexus fails independent gemological re

Its a signity cz. Nothing more. Hence the reason that Diamond Nexus does not have any labs. They rent an office suite in Franklin, Wisconsin. They purchase signity cz and call it synthetic diamonds. This is why they have no proof or evidence to the contrary. Only fake testimonials. Just like that collection of steak knives you see on TV at 2am whose price is just to good to be true.

Classic, I love your lead off in this post...for a second I thought you were one of their 'happy customers who post all over the web' as well <img src="http://talk.jewelry/styles/default/xenforo/smilies/graemlins/default/smile.gif" alt="" /> (I've seen a few myself, they were quickly outed on other boards...)

Glad you were able to get a refund.

Also, I'm glad you noticed the plagarizing - for a bit, they had some stuff right off our FAQ on their site with a very minor change...

Oh well the good news is word does seem to be spreading about this company.

Re: Diamond Nexus fails independent gemological re

Gosh, I am so glad that I found this site before I got engaged! We were looking at DNL for the fact that they were #1 popping up every time we searched and positive information seemed to be all over the web concerning their product.

how long have they been around? it just seems like recently they are getting a lot of negative marks.

I tried. Here are there responses:

Thank you for your inquiry.

We have not published the laboratory analysis of the Diamond Nexus gemstone on our website as the full analysis is dozens of pages in length. The new website we are building, which we internally call DNL 2.0, will have a much expanded gemstone science section including some videos of the manufacturing process. Look for this late in the year.

Please let me know if I can be of further assistance to you.

Warmest Regards,

I wrote back asking for just the names of the labs and this was their reply:

Thank you for your inquiry.

The names of the labs that have performed the tests have not been released from the boards as of yet, but this will be on the new version of our site also. Believe me, this is just as suspenseful for you as it is for me. Since my introduction into this company, I’ve loved learning as much as I can about our product. It’s extremely fascinating!

Please let me know if I can be of further assistance to you.

So there you have it. Nameless, faceless, and most likely fictitious 3rd party labs. But at least we can look forward to a DNL 2.0!
Complete with videos and more junk science.

It kind of reminds me of that diet drug, Lypozene. If you google it, there is a non-profit organization that tests a lot of these fake diet drugs and posts the results. They have proven that its nothing more than a fiber supplement (which will curb your appetite, but only a little). On their commercial they speak of clinical trials performed at a "university." However several groups including this non-profit organization have tried to find out which "university" performed the test, but they refuse to divulge the name.

I wonder if this same university happens to have 3 independent laboratories on campus . . . .

I am respectfully posting this information. I appreciate all of the information posted about DNL because I am searching for a ring and that company was at the top of my list. Of course I will stay away after reading these posts. I know the ads at the top of this board rotate and there is a message saying they are provided by google...but DNL has one that keeps popping up. I copied and pasted from this message board header....SEE BELOW.... I wish there was a way to block this ad on the boards. I think others may associate it with betterthandiamond, as I did.
