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 Diamond Simulants display the coveted "Hearts and Arrows" effect.

2 years later cracked. warranty not valid  by Angelina on 6/12/14

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.

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.

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.  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!
