Impressed the jeweler.  by jane on 5/1/13

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.

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!!

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!!!!!!

Oh, So Happy  by MayaD on 2/28/13

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!

Beautiful Work with Fire!  by Discovered :D on 2/27/13

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!

Looks Good  by Jeff on 2/13/13

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

Amazing rock, but keep in mind...  by Jon H. on 1/7/13

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...

Jeweler approved!  by B Evans on 9/25/12

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!

Perfect Balance  by Neesie on 3/7/12

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,
