    2. Brilliant Earth

    Brilliant Earth is a highly popular online retailer that focuses on diamond and gemstone ethics. Their natural diamonds and mined gemstones have GIA Origin Reports to help put wary minds at ease over conflict diamonds. 

    Colored Gemstones

    They also carry colorless lab grown diamonds and fancy colored lab grown diamonds. It's a small collection of 20. Almost all of them are a vivid yellow. Some of them have this gorgeous orangey swirl in them too, like this one below: 

    1.32 Ct. Fancy Vivid Yellow Radiant Lab Created Diamond

    Majority of these yellow diamonds are over 1 carat and GIA certified. These are the only lab yellow diamonds certified by the GIA on our list today. The stock at Brilliant Earth frequently changes. Today you might see 20 yellow lab diamonds in their inventory, but there might only be 3 the next day. 

    The prices of yellow lab colored diamonds at Brilliant Earth are going to be a bit higher than other online retailers. They also have a wide selection of ring settings.

    They also offer a 3 year maintenance warranty with an option to re-up at the end. The price of it depends on the cost of your purchase.  

    3. Clean Origin

    Fancy Color Diamonds

    Clean Origin is a retailer that exclusively sells lab-created diamonds. Like the others, you can select from their inventory of loose yellow lab diamonds and build your own engagement ring

    Currently, they carry around 20 yellow lab created diamonds of different diamond grades. Clean Origin usually sits near the top a lot of our guides and comparisons on where to buy lab grown diamonds, but not today. 

    It’s a small selection, so you don’t have a lot of wiggle room with your choices. If you’re looking for high intensity, this is not the one. I do love a couple gorgeous banana-yellow diamonds that I haven’t seen at our other picks. But the others are mainly light yellow

    The carat weights don’t go over 2 carats. They’re all certified by the International Gemological Institute too.

    I think that Clean Origin’s prices for colorless lab diamonds are great, but I don’t feel it’s the case with these. A couple of them may be worth it, but the majority seem like too much for how light they are.

    The ring settings at Clean Origin are unique and beautiful. I’ve always liked them as a whole. I also love the way their 100 day return policy gives customers some added peace when receiving their purchase in the mail.

    4. Ritani

    Yellow Diamonds

    Ritani is a ring setting designer that has ventured into the world of loose diamonds. The ex-CEO of Blue Nile joined the company in 2014, bringing all their ideas with them. 

    They only carry fancy yellow diamonds. You have the option between lab-created yellow diamonds or natural fancy yellow diamonds. 

    Compared to the others on our list, Ritani has the smallest selection of lab grown yellow diamonds. Currently, they have 4 yellow lab diamonds in stock. Stock always changes though, so keep your eyes peeled. 

    I do like that they have radiant shaped yellow lab diamonds. James Allen’s lab grown yellow diamonds in the radiant shape were square radiants, not the elongated shape. All of them are IGI certified.

    1.01 Carat Radiant Yellow Diamond

    Ritani’s ring settings are expensive compared to other online retailers. That’s to be expected though, since they’re a setting designer first. If you’ve got your heart set on a classic solitaire settings, I wouldn’t get it from Ritani. But if you’re looking for something that stands out with lots of sparkle, you might want to take a look. 

    They’re one of the very few online retailers to offer a lifetime warranty for their ring settings. James Allen is the only other retailer on our list today that gives all of your routine maintenance free for life. 

    FAQs When Buying Lab-Created Yellow Diamonds Online

    Here are some of the most popular questions asked about buying yellow cultivated diamonds online. 

    Are Lab-Created Yellow Diamonds Good For An Engagement Ring?

    Synthetic diamonds have the same overall durability as mined diamonds. Their hardness level for scratch resistance is 10. 


    Even buying natural yellow diamonds isn't as expensive as other fancy colors, but having a lab-grown option still makes them affordable for people who might not be able to afford otherwise.

    And with the growing interest in colorless diamond alternatives, a lab created yellow diamond will make a perfect engagement ring.

    Is It Cheaper To Buy Lab-Created Yellow Diamonds Online?

    You’re going to have the best luck finding lab-created yellow diamonds online instead of locally. Honestly, it’s got less to do with price and more to do with finding them. 

    Five years ago, places like Kay and Jared refused to carry a loose diamond in their inventory online or in-store. They also refuse lab grown diamonds in their cases. Today, that’s not true. The diamond industry is changing. 

    Most types of yellow gemstones are for people with a specific taste. Many physical stores aren’t going to pay a bunch of money to a vendor of yellow lab diamonds, hoping they’ll sell. These stores only sell what’s popular and what everyone wants. 

    Overall, lab grown diamonds and natural diamonds are cheaper online than in-store.

    Are Lab-Created Yellow Diamonds More Expensive?

    Natural fancy colored diamond jewelry is highly expensive due to the conditions needed to be gem quality. However, a yellow natural diamond the cheapest price of most fancy colored diamonds. . 

    Lab grown diamond rings can be between 20-70% cheaper than a natural mined diamond ring of the same grade. For lab grown colored diamonds, you’ll see around a 20-40% difference. 

    Here’s a price comparison of our online retailers between their natural yellow diamonds and lab grown yellow diamonds. Clean Origin only carries lab diamonds, so they’ll have no direct comparison. 

    What Should You Look For When Buying Lab-created Yellow Diamonds?

    Here's the things to keep an eye out for when looking for yellow lab-grown diamonds online: 

    Cut & Carat

    We often put having the best cut grade above anything else with colorless diamonds. It controls the overall brilliance and beauty of your white diamond

    It’s different with colored diamonds. Instead of round diamonds being the best shape-they're actually the worst shape for colored diamonds. 

    The best diamond shapes for yellow diamonds are radiant cuts, cushions, or ovals.

    Here's why...

    These shapes display diamond color much better than a round yellow diamond. You should avoid them because the color is diffused. 

    Don’t worry about the cut grade. You should be looking at its length-to-width ratio and other proportions to see if it matches the “ideal grades” for that diamond shape. 

    Like all diamonds, the price of a lab grown yellow diamond will rise as you increase carat weight. However, the increase isn’t too bad if you’re starting lower, like from a 1 carat to a 1.5 or 2 carat diamond. Going from a 1 carat to a 4 carat will cost you a pretty penny. 


    Lab-grown yellow diamonds should be eye-clean, or free of inclusions. Inclusions happen during the formation process. 

    Natural diamonds have a variety of different inclusions, but lab grown diamonds have metallic inclusions instead of crystal inclusions. Those types of inclusions aren’t as noticeable. 

    Most of the eye-clean lab-grown yellow diamonds I’ve seen have SI clarity. 


    Fancy colored diamonds are graded by the 4Cs, but their color has special grades too. Colored diamonds are assessed by their tone, saturation, and color hues. 

    Light yellow diamonds are very popular and less expensive. Yellow lab diamonds are most often a vivid yellow since those are in demand and go for higher prices. All they have to do is introduce nitrogen atom to the pure carbon atom

    The most valued lab-yellow diamonds are going to have a bright yellow look throughout the stone. A yellow diamond that has no orange or brown in it is considered top-quality (even if you’re like me and love that orange swirl color).

    Gemologists call these canary diamonds, and they are still a lot cheaper than blue lab created diamonds.

    Red Flags When Buying Lab-Created Yellow Diamonds?

    Here’s just a couple things to watch out for when buying a lab-created yellow diamond engagement ring.

    Canary Diamonds

    Gemologists call diamonds with pure yellow hues canary diamonds. If you look them up on the web, you’ll find reports of sites saying all yellow diamonds are canary diamonds. There’s no actual set standard on the requirements for a canary diamond

    Grading Report

    You’ll want to make sure the stone you’re getting is indeed a lab created yellow diamond. The best way to ensure that is through a grading report from a reputable lab. For lab yellow diamonds, we recommend GIA, AGS, HRD, and IGI grading reports.

    You shouldn’t ever buy a center diamond without a grading report.
