100% Satisfied

This is my second order with Diamond Nexus, and again I'm completely satisfied. I honestly don't understand the appeal of mined diamonds anymore, especially when there are alternatives as good as these! This ring is absolutely beautiful!

Just what she wanted

This ring did the trick! My girlfriend was blown away by this ring. It sits low on her finger and does not get in the way of her daily work so she does not need to worry about wearing it. It is definitely an eye catcher and well worth the price.

I love my ring!!!

We bought the Callisto engagement ring last year. Can you believe it -- it still sparkles like new! We got the white gold and it still does not need to be re-rodiumed. I often forget to remove it while doing housework, yet it still looks new! This ring makes me happy every single day.
Happy customer, 12/4/2016


A-M-A-Z-I-N-G! This ring is so much more beautiful in and on hand. It was even shipped before the expected date. Thank you Diamond Nexus! You have gained a customer for life. Next purchase is a new wedding band for my husband.

I loved this ring. I say "loved" because I misplaced it a couple days before our wedding. Before losing it, I received so many compliments. Every time I looked at it I was amazed at how beautiful the ring is. Keep up on the cleaning because it does make a difference. It's been almost two years now and no sign of the ring. When we get the money, I will definitely want to purchase this ring again.

Diamond Nexus responds: We are so happy that you chose Diamond Nexus for your engagement ring. Though, hearing that you lost the ring does make us very sad for you! We are very happy to work with you to see a new Callisto ring on your finger so feel free to contact us at any time at and we can assist you in getting a new ring on your finger!

Love the ring..... wish it came with a matching band.. it is so pretty in person. Very different and people rav about it daily:-)

Don't believe what you read online.

I almost didnt order this ring because I read negative stuff about the company online. But, I realized that what I was reading was on the site of one of Diamond NExus's competitors. Seems like some people can't win on their own. My fiance got this ring in october and it's been perfect. I recently took it to a jeweler to have it cleaned and he couldn't get over what a amazing "diamond" I had!

Diamond Nexus saved us thousands and I have a beautiful ring that I treasure.
