Infographic: Mined vs. Manmade

I have read that if the diamond in the ring is lost or damaged it will be replaced, but what if one of the smaller detail stones has fallen out of the engagement ring. Would it also be covered under the warranty?

Diamond Nexus response: Great question, Olivia! While Nexus Diamond™ alternatives can be replaced for the lifetime of your ring, missing stones due to normal wear and tear are not covered. However, we will happily replace missing stones for just the cost of the stone and a nominal setting fee. For more information, contact a Customer Care Advisor 1-800-509-4990.

My daughter and daughter in law have Nexus wedding sets. Absolutely gorgeous! Both gals have had their rings over 10 years and they still are as beautiful as when they first got them! My daughter’s ring was damaged and she sent it back in and it was fixed and back on her finger in no time. I have lost the diamond on my wedding set and found myself looking online with Nexus for my replacement set. However, while I am deciding on which set I really want & while I wait for the “little bird” to come whisper in my husband’s ear for me, I understand that Nexus can also reset a replacement stone in the setting? Can you tell me about that process? Thank you.

Diamond Nexus response: Great question, Cassandra! We are so happy you're considering us for your stone replacement. The process is easy, just call a Customer Care Advisor at 1-800-509-4990 and they can walk you through the details and answer any questions you may have.

We bought my first Diamond Nexus diamond 5 years ago and it and the palladium wedding band has held up beautifully! We have bought two more rings since then. We couldn’t be more pleased with the quality, the cost, or the great customer service. Thank you!

Do you have a catalog with sample of men's wedding rings? I'd like one with larger than average stones. I tried calling your number, and it will not go through. You can email me back. Thank you.

Diamond Nexus response: Hi, Jesse! We're sorry you weren't able to get through to us. A Customer Care Advisor will be in touch shortly.

I absolutely love my princess Abigale engagement ring. What is the best thing to clean this ring with?

Diamond Nexus response: Hi, Jina! We recommend cleaning your ring with warm water, soap and a soft-bristled toothbrush. You can also request a Spa Day where we will thoroughly clean, inspect and polish your ring to perfection. If you have any questions, a Customer Care Advisor would be happy to help 1-800-509-4990.

We bought a loose Nexus diamond about 6 years ago. It has turned dull and scratched. We have it in our own setting. Will you cover any replacement on it?

Diamond Nexus response: Great question, Michelle. We're sorry to hear about the damage to your Nexus Diamond alternative. Our stones come with a Lifetime Stone Guarantee. If anything happens to your Nexus Diamond, we'll replace it free forever. The guarantee is void if another jeweler sets or works on your ring in any way. If you have more questions feel free to reach out to our Customer Care team 1-800-509-4990.

Does a nexus diamond show like a cz , just wondering !

Diamond Nexus response: Great question, Nicole! The Nexus Diamond is much closer to mined diamonds visually and in the manner in which they wear. While a well-cut CZ may look similar to a diamond when it is new, it is a weak and porous stone that easily deteriorates, scratches and becomes cloudy.

I see that your warranty will cover the stone (chip, scratch, discolor, lost) but does it also cover the cost for the ring band being resized?

Diamond Nexus response: Great question, Jackie! Along with our Lifetime Stone Guarantee, we include one free ring resizing on most new rings, up to one year after purchase. If you have more questions, give us a call at 800-509-4990.

what is the difference in the stone if it is "certified"?

Also, where are your stores located or are you only an online source?

Diamond Nexus response: Hi Sheila, great question! The difference is that our certified stones are sent to American International Gemologists (AIG) to be graded and certified exactly the same as mined diamonds. Certified Nexus Diamonds have a laser engraved certification number that is invisible to the naked eye but can be seen under magnification (and appears on your paperwork). Classic Nexus Diamonds are the same stones as certified stones, however they do not go through the certification process. We do not have retail stores and exist solely online.

How does the Nexus diamond compare to mined diamonds as far as hardness? Will I have to worry about it chipping? Do you warranty your diamonds/rings?

Diamond Nexus response: Great questions! The Nexus Diamond is a 9.1-9.2 on the Mohs scale of hardness, whereas a natural diamond is a 10 on the Mohs scale. They are covered under our Lifetime Stone Guarantee, so if anything were to happen to it, we would replace it for free.
