Details

The Round Brilliant cut is by far the most popular and most researched stone shape available today. For almost 100 years, diamond cutters have been using advanced theories of light behavior and precise mathematical calculations to optimize the fire and brilliance of the Round Brilliant cut. Due to the refractive qualities of the curve of the stone, the Round Brilliant is known as the brightest, most sparkling design there is. A testament to our cutters, all of our Round Brilliant cut Contemporary Nexus Diamonds™ display the coveted "Hearts and Arrows" effect.

  • Available in a range of carat weights. See menu above.

So Happy.

In Dec 2016, my center stone from my engagement set fell out and was lost. Replacing the stone was not a priority at the time because kids sports, bills, etc took precedent. After much discussion, we decided to start looking at alternatives to replacing the stone. My husband and I came across Diamond Nexus website and started doing research, and reading a ton of reviews. 6 mos after starting the research, we finally made the decision to have a loose stone set into my ring. Because of the amazing pricing, we even upgraded the size of the stone (from original .75 carat to a 1.03 carat). We spoke to a customer service rep who walked us through the process. We sent for the kit, and once it arrived, we sent in the ring and paperwork. My ring arrived today! I am so excited about the beauty of it!! It is BEAUTIFUL and I couldn't be happier to be wearing my ring again!

Mistake on shipping but they more than made up for it! Glad I shopped here!

I loved how brilliant the stone was. I DID have some trouble when ordering. My shipping address was different than my billing address and they accidentally sent it to the billing address. So happened that I was leaving out of town with my fiance the same day I expected the shipment and was going to pop the question on the trip. UPS and DN couldnt resolve the issue for me even though they tried their hardest. Since I had planned an ENTIRE expensive trip around the proposal their customer service department basically gave me a blank check to cover the expense of the trip so I could re-do it. I was impressed at their willingness to try and make up for the mistake. I was able to call in a favor from a friend of a friend that worked high up at UPS and was able to get the package held up at a UPS store and I saved the day. I told this to the customer service rep that the discount was not needed but they still gave it to me!!! Thank You DN!!! The ring is beautiful and I'll be ordering the wedding band from you as well!

Great customer service

The stone was scratched up after 5 years but customer service offered to resolve it with a replacement.
ennifer, 2/1/2017

Wow, Just Wow!

Outstanding quality, brilliance and craftsmanship. I purchased this 2.55 carat stone and had the awesome jewelers at Diamond Nexus set it in a gold ring that I owned. The process was easy. I get compliments on it every single day!
Susannah, 11/1/2016

Fantastic Diamond

I loved this diamond. I returned it to get a bigger one! It is flawless and my jeweler was stunned at how it sparkled. I can't wait to put it in my engagement ring, such a great purchase.
Dani, 10/26/2016

Don't order, it's a scam

The weight of the real stone that you will receive are different then the information that showed on the page.
I purchase 0.25 carat and got 0.35 carat
another stone should be 0.46 carat and got 0.9 carat.
It mean that those stones are just big fake.
I contact support they offer me to send back the stones to have the refund, I used a logistic company to send it outside of U.S and it's not worth to send it back.

** Diamond Nexus response:

Hi Dani -

I'm sorry for the confusion: we use carat weights that are equivalent to the same diamonds. That way a customer can understand how big their stone will be compared to a diamond. I'm hoping that's the case here and that we didn't simply send you the wrong stones. If the latter is the case though, please let me know!

Thanks,

Kyle Blades

Excellent!

I purchased a 3 carat nexus diamond to replace the centre stone in my wedding set. It is absolutely stunning. The deliver was quick as well. I will definitely order again. Glad I found you!!!!
Mary, 8/17/2016

I love my Nexus diamond!

My husband researched man made diamonds and found Nexus to be the most brilliant. He was right. I had a 2 carat engagement ring with a faux diamond that we had planed to replace when we could with a real diamond. Now that we have found Nexus diamonds, we don't feel the need to replace with another diamond. Nexus is a diamond, its just man made. I have a real diamond double row ring enhancer (guard) that my solitaire sits in, and together they are stunning. I get compliments almost daily. I take it to a local jewelry store once a month to have it cleaned and they always tell me how "brilliant" it is. I love it.

Beautiful diamond

This loose diamond is very beautiful. I am very happy with the purchase. Their customer service is top notch and they really care about your needs. Thank you.

2 years later cracked. warranty not valid

Why buy a loose stone with a lifetime warranty that is void the second you have your jeweler set it for you????????? I bought the 1.75ct round in 2011, in 2014 it cracked, called customer service and was told I would have to send my wedding ring to them, BUY a new stone and have it shipped back to me for a new warranty to be valid. what is the point? You know it doesn't cost them nearly a much to make the diamond nexus that I paid $175 for. The jeweler who set it in 2011 was a fine jeweler and if something was wrong it would have happened alot sooner than 3 years!!!!!! So I am out the money and they want me to buy a new stone. BAD customer service, no point in buying a loose stone because it's voiding the warranty as soon as you have it set. extremely disappointing to say the least.

Diamond Nexus responds: We are very sorry about your experiences but we don't honor a lifetime warranty on our stones when another jeweler sets them or works on any ring with our stones in it, and this is on our warranty information that comes with every purchase. We do have a lifetime warranty on our stones as long as our jewelers do the work and repairs. Please contact us here at 1-800-509-4990 with further questions.
Roi , 3/17/2014

I've been waiting more then 20 days and still didn't got my order yet

I paid $50 for the shipping and you send it by regular mail and not express-20 days and counting

Diamond Nexus responds: We are sorry for any inconvenience, but if you can please contact us here at 1-800-509-4990 with your order information we will be happy to look up the order and look into the status for you.

...

the stone I got from diamond nexus is very pretty, but I am very disappointed with the fact that to set the stone on a ring setting I got from another store with Diamond Nexus is so expensive! it is literally going to be the same price as the stone itself...
My wife loves the stone but is still unable to wear her ring because of this.
the kid, 10/29/2013

on fire.............

When the loose stone arrived......I opened the box, and I could feel my face smile. The 1.5 round stone was brilliant and sparkeld like a twinkling star at night. My wife and I have been married for over a year, and I gave up trying to find a diamond. For now, this will be the stone on her finger, that all will see with envy. thank you Diamond Nexus

Impressed the jeweler.

Just took my stone into the jeweler to have it set into a necklace with existing diamonds. He asked where I got the stone and said it was a very good quality. Was happy to tell him about Diamond Nexus and
how happy I have been with the stones I have purchased. You won't be disappointed.

Beautiful Classic cut diamonds

I have nothing but great things to say about the beautiful diamonds I purchased. They are of great quality and very affordable. I am glad I found this company and highly recommend buying a diamond simulant from this company!!
love it , 3/25/2013

a keeper

i purchased the 3.05 ct classic round and it looks so real, the size was perfect, why spend thousands and thousands of dollars when you can not tell the difference honestly. it has a nice weight to it that made it feel more real too. you will not be sorry!!!!!!
MayaD, 2/28/2013

Oh, So Happy

I bought 2 of the round classic .46 carat stones to replace the bloom cut cz ones that came on my Tacori IV engagement ring. Google it. The stones that came on my ring looked very fake and have very little sparkle in most lighting situations. When I got my Diamond Nexus stones I compared them to the CZ that I was replacing and a pair of natural diamond stud earrings that I have in direct sunlight, fluorescent light in the kitchen, low indirect lighting, and my bathroom lighting. The Diamond Nexus reacted to each lighting situation with the same fire and sparkle as the natural diamonds. The Diamond Nexus made my natural diamonds look dirty and yellow in comparison! The CZ looked like glass and I am so happy they aren't in my ring! The cut of the Diamond Nexus stones is the perfect hearts and arrows cut, it makes the stones look completely realistic!
Discovered :D, 2/27/2013

Beautiful Work with Fire!

After a decade of having the setting left on a shelf I decided to upgrade my wife's wedding ring. She has a problem with conflict diamonds and would not let me replace the missing stone. So, discovered the Nexus option. Ordered the loose stones and had it upgraded. The local Jeweler had never seen anything like it!

Reset the piece with larger "diamonds" and it came out Amazing! There are so many positive and uplifting adjectives to descibe the finished work...

Yes, a jeweler can tell upon close examination but it will impress the other .99999% of your peers. Next year? A much larger solitaire in a single setting! Wow!
greytexplorer, 2/21/2013

WOW!!!

Great color and clarity! You have to see it to believe it! :)
Jeff, 2/13/2013

Looks Good

It looks good but when it was mounted it for sure didnt fool the jeweler like some have claimed the Jeweler said it looked like CZ which could be because i meant to buy the signature series and bought this instead but just know it only fools peoples eyes not a jeweler. here is to hoping it doesnt get cloudy
Jon H., 1/7/2013

Amazing rock, but keep in mind...

I ordered a loose round stone, and it arrived much sooner than I had expected, nicely boxed, and elegantly presented.
It shined a little nicer than the CZ that came on the setting I wanted to have the DN stone mounted on. I was excited to get it to the jeweler and see what she had to say, without me mentioning that it isn't a real diamond. Well, as soon as she held it, she immediately said it isn't a diamond, because it felt twice as heavy as a diamond of the same size. She grabbed her little magnifying piece and looked into it, and said the facets are not cut like that of a diamond, so that was another indicator. Lastly, she said you can never read small font letters through a diamond (which I had heard somewhere), but sure enough, you can read through one of the DN stones if you lay it on top of a paper with small writing.

None of these are bad things, but it is MUCH easier than I had thought for someone to tell that it isn't a diamond.
My jeweler did comment on how much more brilliantly it shined than the CZ she had removed from my setting, and on the colors that it refracted, or the "fire"; basically saying that it was prettier than a CZ, but again clearly not a diamond (I could barely tell the difference between the three, haha).
Another advantage she said was likely the hardness (resistance to scratching) that this rock should have, even though I don't know the numerical value on the Mohs Scale (I'd assume 8.5 - 9), and it's likely not to loose it's shiny qualities with time.
I think it was the best way I could get my now fiancé a ring that she would love, and I can currently afford, considering we're just starting to make some money after college :D
Well she LOVES it, and doesn't even think it's necessary to replace it with a naturally mined diamond when we can... Either way, this one will be special to her forever!
I hope it passes the test of time, so good luck to everyone else thinking about doing the same...
B Evans, 9/25/2012

Jeweler approved!

I purchased under a half carat I think a few years ago, when I took it to have it set into a ring, the jeweler smiled and asked if it was the Leo diamond by Kay! I told him it was Synthetic and he was shocked! He examined it and said it was the best synthetic he had seen. I love it and so does everyone else!
Neesie, 3/6/2012

Perfect Balance

I bought a stone to replace one from a custom piece that had been lost. I have ethical issues with stone mining and production around the world. It's hard to balance the pretty sparkly things you want with what it take to get them to a sales floor here. I thought I would try the man-made route.

I couldn't be happier. The shipping and service is second to none. All questions were answered promptly and none were too silly. I was made to feel welcomed and never rushed. Important because stones and jewelry of this type are important matters not to be treated frivolously.

My jeweler huff and puffed a little bit but finally admitted it was mostly because I didn't buy the stone from him and grudgingly admitted that he felt the quality was superb for a synthetic stone.

The replacement stone was set and it looks lovely. Noboby knows except me and that's as it should be,
schotze, 12/2/2011

Beautiful Stone

I have the 2.55 round. I had it mounted in a 6 prong white gold solitaire setting. The jeweller was impressed, said it looked better than moissanite, and asked where it came from.

I was in church one evening and overheard 2 ladies in back of my seat, talking, one of them said (while peeping at my ring) "Girl..that's the real thing I know one, when I see one.., wow" I just turned and smiled.. lol

I can not wrap my mind around spending 8-20,000 grand for a "flawled" stone, but I want quality. Diamond Nexus does it for me!

Oh.. I have had the 2.55ct stone for 5 years, no discoloration at all.! I also have other rings by Diamond Nexus...
Cathy, 11/28/2011

DIAMOND NEXUS LABS..FABULOUS!!!! GET ON BOARD

I FIRST PURCHASED 3 LOOSE STONES AND HAD THEM PUT INTO A SETTING (PAST.FUTURE.PRESENT)ALWAYS WANTED ONE, WELL MY JEWELER HIMSELF WAS IMPRESSED..THE RING WAS SET IN WHITE GOLD AND THE MIDDLE STONE IS 1CT AND THE SIDES IS .5CT THATS A 2 CT RING THAT COST ME 500.00..IF PURCASED IN A STORE IT WOULD BE 10,000...EVERYONE COMMENTS HOW LUCKY I AM TO HAVE SUCH A WONDERFUL HUSBAND..WELL I AM BUT NO-ONE NEEDS TO KNOW THE REAL DEAL...THEN I PUCHASED THE PENDANT..1CT..NOW I JUST BOUGHT EARINGS...HAVE TO HAVE THE SET...AS IM WRITING THIS I THINK I WILL PURCHASE A 1.28CT TO REPLACE MY WEDDING RING...ITS ABOUT TIME TO UPGRADE.

Beautiful Stone

I originally bought the Angelix ring and matching band to replace my engagement ring/wedding band. The ring was beautiful but I couldn't wear it since I had a deep sentimental value on my original set so I returned it and decided to purchase a loose stone and have it mounted on my engagement ring (the original diamond was 1/5 of a carat). I had a 1.24 loose diamond simulant mounted on to my engagement ring by diamond nexus labs and soldered my wedding band to my engagement ring together. It's absolutely breath taking! I decided not to purchase the certified stone because I was told by the representatives that there is no difference in the 4 c's of the stones. At times I feel like my diamond looks "fake" because it's flawless and my wedding bands (I have two channel bands on either side of my engagement ring) are real diamonds with poor clarity and color so the DNLdiamond stands out a lot more. I have recieved a lot of compliments on my DNL stone and no one knows it's a simulant and not a diamond. Sorry DNL but you will remain my best kept secret!

A Wedding too Remember

Since my Fiancee, loved her engagment ring so much it was only fitting, that I get her the stones from DN to make her wedding band and our 1 year anniversary band... Now that the bar has been set its only right I keep the standard up. purchased 8 .25 carat stones and she loved them just the same.
Prince Charles, 10/30/2011

Engagment to Remember

Wanting to propose to my Fiancee required the right ring and since all the recent media coverage on blood diamonds had us both concern we decided that the better option from on would be to purchase a lab created diamond regardles of the occassion. my quest to just that is what led me to diamond nexus. I purchased a 2 carat loose stone for her that was set in a setting of my design. To say she loved it was an understatment and the compliments that she receives are unbelieveable even from jewellers.

I wanted to propose to my Fiancee and I knew money was no object, however with all the recent media coverage regarding blood diamonds she was concerned that the diamonds she already own may be blood diamonds. After much discussion she decided that she felt a lab created one was the way she prefer to go from now on, elimiating any doubt. And my quest to find that perfect stone which led me to "Daimond Nexus". I purchased a 2 Cart loose stone to be set in the setting of my design. Long story short she loved it she was in tears the day I proposed and once she learned there was no chance of it being a blood diamond ever she was even more trilled. The complimets she get from every one that seen it is just unbelieveable, she happy and I'm just excited she said yes. However only one problem she refuses to by anything else where so now I've gotta to purchase only diamond nexus stones for her lol...

An upgrade that really gets noticed!

I sent my original engagement ring in to DNL and had them replace the original stone with a 1.67ct round stone. They did a fantastic job. They called and discussed the new prongs and were able to put in new ones in platinum. Fantastic sparkle!
Gee, 10/21/2011

Simply stunning!

The diamond I ordered is so beautiful! It's taking my breath away, and everyone else's every time someone glimpses at it.
I am 200% satisfied with my purchase!
