Minimum carat weight. You may receive a slightly higher carat weight.
Clarity grades how clean the diamond is. Fewer tiny inclusions means higher clarity.
All our diamonds are 100% eye-clean.
Color grades how white the diamond is. D is the whitest; Z has a faint yellow tint.
All our clear diamonds are F or higher, in the "colorless" range.
Cut is how well the diamond is faceted, not its shape. A great cut sends light back at you for that signature sparkle.
The top cut grade depends on shape: "Ideal" is the highest for round diamonds; "Excellent" is the highest for fancy shapes (oval, cushion, emerald, and so on).
Every Next Diamonds stone is graded the highest for its shape. Maximum brilliance, no compromise.
Shape is the outline of the diamond when viewed from above. Round, Oval, Cushion, Emerald, and so on.
All our diamonds are lab-grown, and they are real diamonds. Same hardness, same sparkle, same chemical structure as mined ones.
Created in a lab, not pulled from the earth: better for the planet, ethically sourced, and more accessible.
Every diamond comes with an IGI certificate, the world's leading laboratory for lab grown diamonds. This independent report verifies the diamond's exact specifications and authenticity.
The certificate is included in the package.
14K gold is durable and the most popular for daily wear. 18K gold is purer and slightly softer with a richer color.
Platinum is the premium choice. Heavier, naturally white, and hypoallergenic.
The shank is the band that wraps around your finger. Standard widths are 1.5–2 mm.
Thicker bands feel more substantial; thinner bands look delicate. We can adjust the width to your preference.
The total carat weight of all the diamonds, excluding the main stone.
The color grade of the side diamonds. We match them closely to the main stone so the whole ring looks consistent.
The clarity grade of the side diamonds. Matched to the main stone so the entire setting reads as one unified piece.
Side stones are also lab-grown. Same ethical sourcing and quality standards as the main diamond.

The ring is absolutely stunning! I couldn't be happier with our experience purchasing my "upgrade" ring for our 28th Anniversary. Ami in Customer Service was so helpful, the ring arrived within 10 days of purchase and I would gladly recommend Next Diamonds to anyone.
Such an easy experience! Website is super simple and can’t beat the price!!! The ring is perfect and I can’t wait to ask her to marry me <3
It is absolutely perfect! Phenomenal craftsmanship!
I HIGHLY recommend Next Diamonds, I was a little skeptical ordering off of Etsy but other reviews were encouraging so I decided to go for it and I’m extremely glad I did. Ami was super helpful in the design of my ring, she was patient and made sure I liked the final design. She was also fast to respond and helpful when some issues came up with shipping. These rings are legit! They come with all the paperwork and I even took them to a jeweler just to make sure and they checked all the boxes! I am IN LOVE with them. They exceeded my expectations and they will be on my finger for the rest of my life. 🫶🏼💎💍
Very nice product and great customer service!
It is beautiful! I have gotten so many compliments. Very, very happy. Thank you
Great communication with seller. The ring is gorgeous and as described. 10/10
I'm happy with it. Beautiful ring.
Absolutely obsessed! Ami was AMAZING, patient, and so great to work with.
I am beyond pleased and grateful for the diamond engagement ring I received. I opted for the 3 carat VS1 F CVD brilliant pear-shaped cut and couldn’t be happier. It came with the IGI certification with excellent marks for symmetry and polish. My now fiancé was thrilled with the choice. In her words, “wow. This is so stunning. You were so intentional with this process, and it shows in the ring and the energy. I have never had such a beautiful diamond, and to know that that was made/designed ethically and sustainably makes it even more special.” The outer box it came in was absolutely beautiful, as well as the ring box as well. NextDiamonds was very responsive and so supportive. I really felt at ease making this kind of financial investment with them, and their rave reviews are there for a reason. Thank you, so, SO MUCH!!
Gorgeous ring and the quality is wonderful! Responsive seller which was appreciative
This ring is absolutely stunning!!! It exceeded my expectations and the customer service was phenomenal. I was kept informed about my order through the entire process. I HIGHLY reccomended this seller and THIS RING!
Beautiful ring and excellent customer service from Ami. She got me just what I wanted and in a timely manner
The team at Next Diamonds were so kind and accomodating throughout the whole process with all my questions and messages to customise my dream ring. I ended up upgrading and modifying bits as my partner and I thought of new things and every bit of our dream came to life. Being from across the world, the time difference almost didn't matter since they were so responsive and transparent with each step of the way. The ring arrived beautifully packaged and it couldn't have been more gorgeous. The shipping was with an excellent courier and arrived across the world within 4 days! I'm already dreaming of my Next Diamonds from them, and I'm so thankful that I got to work with the kind and amazing Ami throughout this whole process.
I’m very happy with my ring. Everything came out perfect just like the the others I have done. I am a repeat customer continually coming back for the quality and outstanding customer service. Well worth every penny.
Always perfect and excellent customer service. Craftsmanship is top notch. Repeat customer always coming back.
Beautiful ring would definitely recommend
although I love the ring, I decided to return it as I’m going to wait a bit as we’re remodeling our kitchen!
Amazing looking ring and craftsmanship now fiancée loves it
I was able to get the ring of my dreams custom made through Next Diamonds. It’s stunning and exactly what I wanted. Thank you so much!
If I could give more than 5 stars I would. Just a great experience from start to finish and would highly recommend Ami and Next Diamonds to all of my family and friends. We were searching for an engagement ring and stumbled upon Next Diamonds. We reached out and Ami responded within minutes. I was in between vacations and had a small window to receive the delivery and they made sure to ship it on time on my specified date. The ring itself was beautiful and my fiancé loved it. We wanted to make further customization after the fact and Ami provided a shipping label for us to return it. This process was even more efficient than many large stores and retailers. Next Diamonds and Ami made the customization, shipped it back to us on the specified date, and was so responsive and great to work with.
This ring exceeded my expectations and I love it so much. It’s the most beautiful piece I’ve ever owned! I was unsure buying online but everything went great and I will definitely be making future purchases from ND!
Most beautiful diamond i've ever seen. Exceeding my expectations. My fiance has been wearing for months now and loves it.
The ring is beautiful and they were great to work with.
It is absolutely beautiful. A perfect ring for a great price. My fiance loves it.
Just received my ring and I'm thrilled! It's stunning to say the least. The craftsmanship is incredible and the ring is exactly what I had envisioned! This was my first time working with an online seller for jewelry, so I was a little nervous going into it, but Ami was amazing to work with and made the process for me super simple and stress free! Turnaround time between placing my order and receiving my ring was also very quick! I highly recommend Next Diamonds and will be back for any future jewelry needs!!
Stunning earrings. Super sparkly and excellent quality.
I purchased two slightly different Eternity rings that I wear on each side of my engagement ring and they are so beautiful together! The three rings together really elevate the look. I can't say enough good things about Ami. Great communication, kind and thoughtful through the whole process. Rest assured that Ami will make sure that you are happy with your purchase. I highly recommend Next Diamonds and I will be coming back for more.
Beautiful ring my wife was so surprised she bawled
great ring, beautiful and great customer service too
A+++ quality & seller! Ami is extremely responsive, knowledgeable, and put any concerns I had about the materials used, or buying experience online at ease. Although I cannot speak about longevity, the ring is higher quality than I expected!
The quality of the Ring let alone the diamond was impeccable. Ami's customer service was a prime attribute of why I had such a successful time shopping with their jewelry business. She was very helpful in all aspects and answering all of my questions and giving me advice. I will very much so recommend this jewelry business for all diamond increase and will be looking into buying more jewelry from them in the future. The item that I purchased from them was a complete match and much more beautiful in person. I can't wait to propose and present this ring to the love of my life.
My fiance loved that she was able to design her ring completely to her liking and it turned out beautiful! Ami was very accommodating and provided excellent customer service. I highly recommend!
Absolutely stunning! I loved loved my custom ring
My special order was absolutely perfect.
The ring is stunning! I couldn’t be happier with my purchase. It continues to my breath away each time I look at it!
Perfect!!! Ring is absolutely amazing and packaging was top notch!
Ami was absolutely amazing helping me customize this ring for my son and future daughter in law. The ring arrived super fast and is absolutely beautiful! I’ll have to update a picture once he proposes! The quality and clarity are stunning, a true work of art. And Ami’s customer service is top notch! So thankful I talked my son into using a custom jeweler rather than a box store. What a treasure our daughter in law will have! Thank you Ami!
This was for a return and a new purchase and I love the new rings! Quick turnaround and seller response
Absolutely gorgeous ring!!! I can't stop staring at it.
