Infographic: Manmade vs. Mined

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.

I absolutely Love my East /West Emerald Cut Wedding Ring Set with the two matching Bands. My Fiance & I couldn't afford a true diamond of that size that he chose for me,,thank gosh for income tax returns!!. My daughter is the only one whom has seen it, & can hardly wait till she receives it one day.
My Fiance & I are to be married in June of 2020. I am so thrilled with the absolute Beauty of the ring & am anxious to start wearing it. Now I need to find some Nexus Jewelry to wear on my Wedding Day!!! 😜

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.

Will the stone or bands become dull or turn my finger green over time? Basically, we are looming for wedding rings so we need to know if these rings witll withstand daily wear.

Diamond Nexus response: Hi Christine! Great question. With proper care, the stones and band will stand up to daily wear. Because gold is prone to scratching, occasional polishing will bring the bands back to looking like new. The only reason they could turn your finger green is if you allergic to any of the metals that are added to gold to strengthen it such as nickel or copper. If that's the case, then a hypoallergenic metal type like platinum is a better choice for you. If you have more questions, give us a call at 500-509-4990!

Can these created diamonds be made in 4 or 5 carat stones and if so how much do they cost . I am only interested in the stone, not the setting. Otherwise a stone in a plain setting. Thank you .

Diamond Nexus response: Hi Judith! Yes, both lab grown diamonds and our diamond simulants can be made in the 4-5 carat range. The cost depends on the cut and size you choose.
