Grown Brilliance
Grown Brilliance really stands out if you’re looking for a huge selection of lab-grown diamonds. Seriously, they have thousands of options, which is pretty amazing. You can find everything from simple solitaire rings to more unique pieces like earring jackets and anklets. They cover a lot of different styles too, from vintage vibes to super modern looks.

What’s also cool is that if you can’t find exactly what you want, they’ll work with you to create a custom design. And get this – they can often have custom pieces ready and shipped in as little as 14 days. That’s super fast, especially if you’re a last-minute shopper or just get excited about a new piece. They source their diamonds directly from growers and have artisans who work exclusively on their jewelry, which sounds like a good way to keep quality up.
They also have some nice perks, like a 10 percent discount for first responders, military, and teachers. Plus, they offer a lifetime warranty and monthly payment options, which can make buying a bigger piece more manageable. They even have a price matching guarantee and run special offers pretty often. Shipping is free and usually takes two days, and you have 30 days for free returns. It’s a solid choice if variety and customization are high on your list when looking for lab-grown diamonds.
Vrai
When you think about Vrai, the first thing that probably comes to mind is their serious commitment to sustainability. They’re all about lab-grown diamonds, and get this – their diamonds are made in a zero-emissions foundry powered entirely by hydropower. Pretty cool, right? Even Leonardo DiCaprio is an investor, which says something about their forward-thinking approach.

What I really appreciate about Vrai is how transparent they are. You can find all the details about pricing and their policies right on the product pages. Plus, every lab-grown diamond comes with a certification that actually includes the country of origin, which not all places bother to do. They also offer a lifetime warranty on their diamonds.
Beyond the eco-friendly aspect, Vrai really focuses on craftsmanship. Their diamonds are hand-chiseled and polished by artisans, and you can totally see the difference. The sparkle on their cuts is some of the best I’ve seen. Some standout pieces that caught my eye were their Knife-Edge Round Brilliant Engagement Ring, some classic Solitaire Studs, and a really nice Tennis Bracelet.

Ritani
Ritani is a solid choice if you’re looking for lab-grown diamonds, especially if you appreciate a really detailed look at the stones. They have this cool platform where you can filter diamonds not just by the usual stuff like shape and carat, but also by things like delivery date, fluorescence, and even the length-to-width ratio. It’s pretty unique, honestly. Plus, they’re really upfront about their pricing, giving you a full cost breakdown, which is always nice when you’re spending a good chunk of change. They also match prices if you find a similar diamond cheaper elsewhere.

- Sustainable Sourcing: All diamonds offered by Ritani are created using 100% sustainable hydropower, appealing to eco-conscious shoppers.
- Lifetime Warranty: They back their products with a lifetime warranty, offering peace of mind.
Things to Consider

It’s a great spot for shoppers who want to know exactly what they’re getting and why it costs what it does. If you’re someone who likes to compare every little detail, you’ll probably feel right at home here. They also have some really popular engagement ring styles, like their Petite 6-Prong Knife-Edge Solitaire, which is a classic for a reason. You can also find lovely necklaces and earrings if you’re not in the market for an engagement ring. For those looking for ethically sourced and beautiful diamonds, Blue Nile offers a wide selection that’s worth checking out too.
Clean Origin
Clean Origin really focuses on just lab-grown diamonds, which is pretty cool if that’s all you’re looking for. They’ve been around for a bit, and the company was started by someone who’s been in the diamond business for a long time, like three generations. That’s kind of a neat background, right?

They use both the CVD and HPHT methods to create their diamonds, and they also try to use recycled metals in their jewelry designs. That’s a big plus for anyone thinking about the environmental side of things. Plus, all their engagement rings come with a lifetime warranty against manufacturing problems. That’s pretty reassuring.
What I found really stands out is their return policy. You get a full 100 days to return something, which is way longer than most places. They also offer free 2-day shipping on everything, which is nice. If you’re looking for a ring, they have ready-to-ship options that get to you fast, or you can design your own. They also have rings for men and bridal sets, and the prices seem pretty reasonable.
One thing to note is that if you’re looking for something under $1,000, you might not find as many choices here compared to some other stores. But if you’re willing to spend a bit more, they have some really beautiful pieces.
Here’s a quick look at what they offer:
- Return Policy: 100 days, free returns.
- Shipping: Free 2-day shipping on all orders.
- Warranty: Lifetime manufacturing warranty on engagement rings.
- Materials: Uses recycled metals in designs.

They really seem to put a lot of effort into making sure customers are happy, which is always a good sign when you’re buying something as important as a diamond. You can check out their selection of lab-grown diamond engagement rings on their site.
With Clarity
With Clarity is a great spot if you’re looking for a personalized touch when buying a lab-grown diamond. They really focus on helping you create something unique, which is pretty cool. You can start with a loose stone, pick a setting, or just browse their pre-made rings and add your own flair. They have a ton of customization options, like over 8,000 ways to tweak a ring, which is a lot to sift through, but it means you can really get what you want.

One of the standout features is their Home Preview service. You get to try on two sample rings at home before you buy. They 3D print them based on your choices – like carat size, shape, and metal – and you can keep them for three days. It’s a smart way to see how a ring actually looks and feels on your finger, something you can’t always get from just looking at pictures online. They also offer free engraving and one free resizing within 30 days of purchase, which is a nice bonus.
While it can sometimes be a little tricky to filter specifically for lab-grown diamonds on their site, a good tip is to look at the categories and sort by price. Often, the more affordable options are the lab-grown ones. It’s worth the extra step to find those hidden gems.
They also have a rewards program and offer financing, making it easier to manage the cost. They even have a lifetime warranty on their products, which gives you some peace of mind.
What you’ll love:
- Home Preview service to try before you buy
- Thousands of customization options
- Free engraving
- Lifetime warranty
Keep in mind:
- Filtering for lab-grown diamonds can be a bit confusing at times.
Rare Carat
Rare Carat is a bit different from the other places on this list. Instead of making their own diamonds, they work with a network of suppliers. Think of it like a curated marketplace for lab-grown diamonds. This approach means they can offer a really wide variety of stones and styles, often at competitive prices. They also provide a free diamond analysis service, which is pretty neat if you’re not sure what you’re looking at.

What I like about Rare Carat is their transparency. You can sort diamonds by all the usual things – shape, carat, cut, color, and price – and then pick your metal. They also have gemologists you can chat with, which is helpful for getting unbiased advice. It’s a good option if you want lots of choices and a little expert help without feeling pressured.
Here’s a quick look at what they offer:
- Managed Marketplace Model: Works with various suppliers for variety and good prices.
- Free Diamond Analysis: Get expert insights on price and quality.
- Gemologist Consultations: Chat with experts for informed decisions.

They really try to make the process of buying a lab-grown diamond straightforward, even if you’re new to it. The free analysis and access to gemologists are big pluses for anyone wanting to be sure they’re getting a good deal.
Rare Carat also offers free insured shipping on all orders and free 30-day returns, which is pretty standard but always good to have. They also provide complimentary ring resizing for 90 days.
