Love it!

Beautiful! Bought to replace lost wedding set I'd had for 28 years. Looks just like it, minus the carbon speck!

I absolutely love this ring! It is a replacement for a mined diamond that I lost, and I have to say this one is even more stunning than my original! I am so happy with this purchase that I am going to order the band that matches it.

Sizing runs large- pretty sparkle

I bought this in yellow gold at the 1.6 carat size at a 6.25 and it is too big for my finger, for sure, but I moved it over to the middle finger and it works nicely, the larger finger balances the HUGE stone. The stone sparkles and is quite pretty. I'd go smaller because the larger your stone the more obvious it is too perfect to be a "real" diamond. Even living in Canada where ethical diamonds are easy to obtain, I'd come back to diamond nexus for price any day.

Beautiful Man Made Diamond

This is one beautiful ring. It isn't the one I ordered but now that I have it I am glad for the mix up.
Disappointed with customer service.

lackluster ring set

My fiance and I looked into different made made diamonds, and although Diamond Nexus has mixed reviews, we decided to give it a try. I like the idea of a man made diamond being more environmentally friendly since there is no mining, and one doesn't have to worry about "blood diamonds," or controlled diamond markets.

Unfortunately, the ring doesn't live up to my expectations. It really doesn't seem to shine and sparkle like the real thing. Also, I have always worn a size 7 to 7.5, and after my fiance gave me a size 7, I had to send it back to be sized down. After having it size at a 6.75, it's still too big! I have to pay another resizing fee for a size that I have never worn in my life.

Now I'm sending my set in a second time, but this time for incursions that seemed to have been created by the complimenting band. I think the "hook" has worn spots into my supposedly hard-as-the-real thing diamond.

I am very disappointed, and at this point, would not want another diamond simulant from Diamond Nexus.

Diamond Nexus Response: Kate, we are very sorry that the rings did not meet your expectations. The look of our stones doesn't always please everyone's taste and that's why we do have our 30 day return/exchange guarantee. As far as the size of the ring, different styles are all going to fit differently. The Endless Days does have a thinner band and is mainly top heavy, so this may account for the smaller size being needed. We truly do hope that you will reconsider and give our product another chance in the future.

Stunning Ring

This ring is more than I could have ever imagined. The quality of the stones are amazing, and the way it looks on my finger is so elegant. I was hesitant at first knowing that this was not a mined diamond, but now that I have this ring, I don't think I will ever go back to an mined diamond again. People EVERYwhere should know about this company. It's rediculous what other companies charge for the EXACT same ring, and NOONE can tell the difference. And I know that as time goes on, the quality of this diamond simulant product will only improve so much that they will really be giving mined diamond companies something to sweat about...and it is already happening! The popularity of this company is only going to grow the more people know about how amazing their product is. I was in SHOCK at the quality, and the beauty of this ring when I saw it finally for the first time. This ring is STUNNING, and the packaging was fun and classy. Absolutely beautiful, and it sparkles so much I can't stop looking at it. Diamond Nexus, thank you!!

I just received this ring for Christmas and I can't say enough! It is STUNNING! It is everything I hoped it would be but even better. I will tell everyone to shop at Diamond Nexus!

I have natural diamonds and wanted a simulated set for travel. All of my best jewelry is yellow gold. The Nexxus set seem too flashy and I finally realized it is brassy look of the setting that I didn't like. Even in yellow gold, my "real" diamonds have white gold prongs; I now understand why my jeweler always makes that suggestion. Sadly, that option is not available here. Otherwise, I think it would have been a great set. I might order in white gold.

Diamond Nexus responds: Thank you for taking the time to post a review for the Endless Days. We want to let you know that many rings can be semi-customized to have white gold prongs. The best thing to do is contact our customer service department by email at customerservice@diamondnexus.com or by phone at 1-800-509-4990 to speak with a representative about the option and what rings can be altered. We have many customers request this and though it isn't shown on the website as an option when purchasing, semi-customizing can be done over the phone with our representatives.

Perfect and looks amazngly real

I was so worried everyone would know it was fake, but after I got and saw how perfect it was, everyone else would be fooled. There is such a stigma with not having a real diamond and I honestly don't like how diamonds are mined and all the politics behind it, but that is just meant to be my personal feelings. This ring is amazing. The setting is top notch. I've showed it to jewelers who admire the setting and when they look close enough at the stone, are only able to tell it is not real because it is too perfect and has no flaws. One even told me becasue of the imperfections, this would cost people upwards of $30k. I love it so much, it is bigger than I thought it would be, but if that is the only complaint I have, all is right in the world. I would recommend Nexxus Diamonds to anyone, except I havent told anyone! ;)

endless days

I just got my wedding set and all I can say is thank you it's the most beautiful ring I've ever seen.

Great deal!

Here is the same ring from Tiffany & Co. ( http://www.tiffany.com/Engagement/Item.aspx?GroupSKU=GRP10034#f+7/0/0/0/0/0 ) for upwards of $5,000!
Just goes to show that DN is the smartest choice when selecting your jewelry! It's so great to get a bargain without sacrificing quality.

I love it!

I bought this ring for myself 2 years ago, as an "I love Me" gift after the end a pretty stressful relationship. It's beautiful, the pictures really don't capture just how stunning it is. I was a little freaked out when, the day after it arrived, one of the side stones went missing. I sent the ring back, they replaced the stone and repaired the ring for free, then returned it in another lovely wooden box. This the initial issue, it has last through fairly rough daily wear, and still looks fantastic. Even with the smallest stone size, it's still pretty breath-taking, while still being delicate enough to look like it belongs on my small fingers. The setting did kind of hurt me for a while, but after digging in to my knuckles for a few months, it gave me a little callus at the base of my finger, so it doesn't bother me anymore. I paid a little over $400 for it, and it was definitely worth it...I'm not sure about close to $700, but I guess it beats $4,000!

Amazingly beautiful!

Have bought several times from diamond nexis and the items are always beautiful, and flawless! This set is absolutely beautiful and what I'm buying next!

My husband and I purchased all of our wedding rings back in May 2010, didn't know of Diamond Nexus at the time. (My engagement ring and wedding band looks just like Endless Days with the princess cut.)

Finally hearing about Diamond Nexus in May 2011 I started researching them and their products. My husband and I decided that we were so impressed we would order DN rings to replace my mined diamond rings for our 1 year anniversary. WOW!!! All I can say is the quality, craftsman ship and the diamond simulants themselves exceed the beauty of ANY mined diamond I have ever seen!!! I am truly blown away that I find myself looking at my new rings a lot!

Thanks DN for ... well ... everything that a woman could ask for (and more) in her wedding rings!
