My fiance loves it and can’t stop staring at it

This ring is gorgeous in person! The setting has a great weight to it and the prongs are so elegant! I got it as a gift for our 15th wedding anniversary. Never ordered a diamond ring online before so I was nervous, but am so happy I did! Great customer service as well. I ordered in a size 7, but then realized I needed a 7.5…customer service changed it for me before it shipped out 👍🏻 A+

Joan Davis (Las Vegas, Nevada)

Absolutely beautiful, we could not be more pleased with our purchase. Stunning ring at an unbelievable price. Nice job guys, thank you!!!

BRADLEY PIERCE (Boise, Idaho)

The diamond is GIA certified, which gave me peace of mind. I didn’t know much about cuts or clarity, but the gemologist explained it in a way I actually understood. Great company to work with.

Designed my dream ring with the team at Modern Carats!

We designed a custom piece together, and the team made it so easy! I thought it would be a long drawn-out process, but it was fast and way more affordable than I thought! We finalized the design in just a few days and I had the ring in my hands just 4 days later! Super impressed with my experience and telling everyone about Modern Carats!

J
Jameson BLAKE (Honolulu, Hawaii)

The payment plan made it possible for me to propose sooner instead of waiting another year. The ring looks amazing and she’s thrilled.

D
David Gray (Madison, Wisconsin)
Great experience. I'd highly recommend this company!

Great experience overall. The gemologist was the opposite of pushy. He asked what I was looking for and gave suggestions based on that - not what cost more. I ordered the ring that same day and it arrived fast, secure, and beautiful.

KEVIN Billard (Colerain, North Carolina)
Overall very happy with this purchase. Don't waste time like I did - just buy.

Compared the exact same carat/clarity combo across four sites. Modern Carats beat them all. And it wasn't even close. Don't waste time like I did - just buy from here.

Brandon garlicki (La Grange, North Carolina)
You guys took the stress out!

The ring is gorgeous, legit looks like it should've cost double. Being able to pay it off in installments made it way less stressful.

Jimmy Cochran (San Diego, California)
looked way better than anything I saw in person.

proposed at disneyland by the castle lol. she freaked out when i opened the box. the ring was shining like crazy. i trusted modern carats because they made the whole diamond thing not feel overwhelming. it got delivered super fast too. looked way better than anything i saw in stores here.

E
EVELYN Bowe (Everett, Massachusetts)
PERFECTION.

I had sent him Pinterest photos for months and I can't believe he found something so close. The ring looks exactly like what I dreamed of, maybe even better. He told me after that Modern Carats made it easy to pick everything out and the payments were simple too. All I know is the end result is perfection.

D
David Benavent (Waterloo, Iowa)

I was honestly scared it might look fake since it was cheaper than other sites. Nope. Certified, gorgeous, and even the jeweler who resized it was impressed.

S
Scott Garcia (Atlanta, Georgia)
Couldn't be happier!

Most jewelers gave me the "custom takes months and $$$" speech. Not Modern Carats. The design process was simple, they were responsive, and it came in way under budget. Couldn't be happier.

David McKimson (Stevensville, Montana)
I left the call with confidence and placed the order same day.

I told the gemonologist what I could spend and expected him to try to upsell me. Instead, he showed me smarter options. I left the call with confidence and placed the order same day.

David Heavern (Chicago, Illinois)
Being able to spread the payments out was huge.

We're saving for a wedding and a house, so money's tight. Being able to spread the payments out was huge. I ordered the ring on a Monday, it shipped Tuesday, and I had it by Thursday. The packaging was discreet so she didn't suspect anything. Honestly it couldn't have gone smoother.

Mia hagen (Midland, Texas)
He told me it cost way less than natural diamonds and I'm glad, because now we...

My ring is lab diamond and I wouldn't change a thing. It looks incredible, sparkles in every kind of light, and fits my hand perfectly. He told me it cost way less than natural diamonds and I'm glad, because now we have more to put toward our wedding and honeymoon!

Matthew Sprecher (Plainfield, Wisconsin)
It turned out PERFECT. Sparkles perfectly and fits like a dream.

We talked about getting engaged for a while and decided together to go with lab-grown. The savings were huge, and we were able to design a custom ring and matching wedding band without blowing the budget. It turned out perfect.

Daniel Johnson (Belton, Texas)
I did a lot of price comparisons and Modern Carats came out cheaper every time.

I did a lot of price comparisons and Modern Carats came out cheaper every time. Ordering was smooth, financing was simple, and the ring blew me away when I opened it. Definitely worth it.

James Campbell (Northport, New York)
I cut it way too close!

Proposal was already planned and I was cutting it close. Modern Carats got me the ring in 3 days. Lifesaver!!

David Thompson (Davison, Michigan)
Insane value!

I literally sent in a sketch on a napkin (not joking) and they turned it into a 3D model. I expected a crazy markup but it was actually less than some pre-made rings. Insane value.

C
Carlos Doughtie (Herriman, Utah)
I'm in love with my new ring, They really nailed the balance.

I proposed in Paris at night under the Eiffel Tower. Cheesy, I know - but she loved it. The ring sparkled like crazy under the lights. I kept second guessing myself when buying online but Modern Carats made it so easy and trustworthy. They custom made our bands too & really nailed the balance between education and quality!

With Our Planet In Mind

Not only are lab grown diamonds identical to a natural diamond, they are a much more environmentally friendly choice as they are produced in controlled conditions, eliminating the need for destructive mining practices. Traditional diamond mining can have a negative impact on local ecosystems and wildlife, as well as contribute to soil erosion and water pollution. By choosing a lab grown diamond, you can have a stunning, high-quality diamond without the environmental impact.

We'll Never Ruin A Surprise

We promise that your order will always be sent in an unbranded, plain shipping box that reveals nothing about its content or sender. We are committed to preserving the element of surprise!
