The deeply fascinating Oval cut gemstone is actually a relatively recent invention; it was designed by a jeweler at Lazare Kaplan Inc. in 1957. Its smooth angles allow for its brilliance to be nearly just as bright and perfect as a round gemstone, but with a larger surface area. Furthermore, the Oval design in jewelry creates a gentle elongating effect for which elliptical gemstones are treasured.

- I needed to replace a 1 ct. oval diamond and chose to go with a lab created diamond through DiamondNexus. So glad I did. I'm thrilled with the quality of the stone and the repairs and work delivered. The time it took was reasonable and the price was way better than my insurance deductible. So happy with the experience. Doubt I'll ever buy another natural stone when these high quality stones are so much more affordable. I got the certified level and appreciated that objective evaluation of the stone.
Beautiful, have them set it for you!
- Bought the stone, and designed a custom platinum ring with forever artisans. I love it so much. It's perfect, and breath taking. I was definitely nervous about going with diamond nexus, but they did not disappoint! People always stop me to see it, and every one thinks that it cost a fortune. I'm so pleased, I'm ordering our wedding bands too. BUT PLEASE PAY ATTENTION!!!! the warranty is goid if you have another jewler work on it! They offer this service!!! Just use them for everything! Mine was a full custom design and every step was easy and pleasant. Michelle was my customer service rep, and helped me the whole time, every worried email or call, all of my million questions. She will get you the ring of your dreams. I've had my ring several months now, and I swear it gets more beautiful every day!!!
The website says, “A Diamond Nexus stone will last forever and never chip, scratch or discolor” - this is false.
My Fiance bought this diamond for me, 2.54 carats, July 2016. The stone was BEAUTIFUL! We had it put into a setting by a local jeweler and it was everything I could have wanted.
It's been almost 1 year since I've had the diamond, and it is scratched along the top. It is supposed to be as strong as a diamond and not scratch but you can see and feel the divets in the ring. Since we put the diamond into a setting by a third-party, the warranty no longer exists. In order for me to get my ring fixed, I have to purchase a new stone.
I don’t want my diamond to have scratches which is why I went to Nexus, because they seem so confident with their “lifetime guarantee” yet mine is scratched and they won’t fix it. So disappointed. I was going to buy more jewelry from them but now I just don’t know.
If they really feel confident in their rings than they should replace a stone that DID get scratched.
**Diamond Nexus Response:
Hi Zachary -
I am so sorry that you're disappointed with your purchase, that's not what we want at all. Unfortunately, any stone can chip or crack, including diamonds. While most people don't believe that, I have seen it time and time again. So while our stone is as strong as a diamond, that doesn't mean that it will never get damaged.
The reason why we don't cover our stones after someone works on them is that we can never be sure the quality of someone else's work and an inexperienced jeweler can easily crack any type of stone. However, we do offer an amazing setting service that allows you to send your ring to us insured, have it set with one of our stones, and sent back to you. I hope you take advantage of this should you choose to purchase from us again.
Let me know if you're interested in ordering a new stone and I'll be happy to wave the setting fee for your troubles.
