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.

Financing was a gamechanger

I loved that they let me finance the ring over time. Honestly made the difference between getting a smaller diamond or the one she really wanted.

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!

The ring looks even better in person than the photos. I catch her staring at it constantly, and honestly I do too!

I had the ring appraised after it came, and the jeweler said I got an excellent diamond for the price. That alone made me feel confident in this purchase!

I spent way too much time price shopping!

I compared prices across like 20 other sites! Modern Carats beat them all by a good margin, especially for a certified lab diamond!

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

The ring showed up in only 3 days, which saved me because I was cutting it close on timing. The packaging was nice and discreet, so she didn’t suspect anything.

Great experience and great company to work with!

I had a couple questions during checkout and just texted them in. It felt casual and easy, not like some pushy jewelry store. Ended up with a gorgeous ring and a simple payment plan that worked for me.

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.

Installments was a life saver!

I was worried I'd have to wait months to afford a ring. Installments let me get it now. She said yes, and I'm paying it off easy.

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.

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.

It was even better than I imagined!

Honestly, the diamond search felt like a cheat code. I knew nothing about diamonds, but after playing with the filters, I had a short list of amazing stones in under 10 minutes.

Almost wasted $1200!!

The diamond I got from Modern Carats was over $1,200 cheaper than a near-identical one from a well-known site I won't name. Just as sparkly, just as certified, 10x better value. Came in 3 days. Win all around!

The ring arrived in 2 days

I don't usually write reviews, but this company deserves one. I was clueless about diamonds before this, and the website made me feel like I knew what I was doing. Ordered in like 15 minutes, payments set up instantly, and the ring arrived in 2 days. When I opened the box it honestly looked like something from a luxury brand. She couldn't stop showing it off to her friends.

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.

Diamond selector tool was fun to play with.

I had the ring appraised after it arrived just to make sure I didn't get ripped off. The jeweler looked at it and said I got a killer deal. That was all the confirmation I needed. The ordering was simple, the diamond selector tool actually helped me narrow it down, and the ring looked incredible on her finger.

Ordering was smooth, the payment option was flexible, and the ring is just perfect.

One of the things I liked most was how clear the communication was. They kept me updated the whole time and even helped when I was worried about sizing. Ordering was smooth, the payment option was flexible, and the ring is just perfect. Even my mom said I did good, and that means a lot.

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.

I didn't want to max out my credit card. Their installment option was a lifesaver. Simple and fast approval.

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.

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.
