Clean Origin Diamonds

Clean Origin company history

Clean Origin was started in 2017 by three jewelry industry veterans: A former global managing director for the Danish jewelry conglomerate Georg Jensen and a third-generation diamond trader; a former CMO of one of the most popular jewelry brands in America, Alex and Ani; and a former CEO of Signet Jewelers, Sterling Jewelers and chairman of Zales and current chairman of the board for Abercrombie and Fitch.

It is no surprise how perfectly they have executed their mission of bringing the best customer service and premium-quality diamonds at the most competitive prices direct to consumers with such a strong team.

Clean Origin has quickly become one of the leading sellers of lab-created diamonds and has made its mark on the industry. They have quickly positioned themselves as leaders in the lab-grown diamond space and direct-to-consumer jewelry sales. Throughout our Clean Origin review, you’ll learn how.

Quick Clean Origin facts

Is Clean Origin legit?

Clean Origin is a legit company that has existed for many years and has amassed thousands of positive reviews from satisfied customers. Clean Origin’s customers love their exceptionally generous 100-day return period. Clean Origin sells some of the highest quality lab-grown diamonds at the best prices we’ve found. Clean Origin is a trustworthy company and one of the best places to buy lab-grown diamond jewelry.

Is Clean Origin a good place to buy diamonds?

Clean Origin is one of our top-rated places to buy diamonds online in 2023. Clean Origin specifically focuses on lab-grown diamonds and is a leading lab-grown diamond jeweler. Their diamonds are exceptionally high quality, and their prices are the best on the market. Clean Origin is an excellent, if not the best, place to buy diamonds.

Does Clean Origin have stores?

Clean Origin primarily sells diamonds online, which is one reason why Clean Origin’s prices are so competitive. However, Clean Origin has expanded its showroom presence, and you can currently find them in Washington DC, Columbus (OH), Chicago, Dallas, and at two locations in Houston. Unlike the Vrai showrooms, at Clean Origin, you can also buy lab diamond jewelry in the showrooms, but some customizations are only available online.

Lab-grown diamonds only at Clean Origin

Clean Origin exclusively sells lab-created diamonds and jewelry. So when you shop diamonds at Clean Origin, you are guaranteed to avoid conflict diamonds and can rest assured that your stone will have a minimal negative impact on both people and the planet.

Clean Origin sells diamonds produced using the two main techniques, High-Pressure High Temperature, and Chemical Vapor Deposition, which you can read more about in our guide to lab-grown diamonds.

Together, the techniques allow them to sell diamonds of almost any size and quality – all at a much lower cost than mined diamonds. Without the negative societal impact and unnecessary carbon emissions.

Clean Origin diamond prices

Based on our in-depth analysis of the lab-grown diamond market and countless reviews, we have consistently found Clean Origin to offer the most competitive prices. Not only are their diamond prices 70-80% lower than for similar mined stones, but often 10-20% lower than many of their competitors in the lab-grown diamond space. The only other diamond seller with comparably low prices is Ritani (read our Ritani review). Clean Origin’s lab diamond jewelry tends to be cheaper, while Ritani’s loose lab diamonds are slightly more affordable.

Loose diamond prices

When we compare the prices of diamond jewelers, we use a reference diamond to compare the range of diamond prices. This is not an exact comparison, but it gives you an idea of the price levels. We’ll do the same in this Clean Origin review.

Our reference diamond has the below specifications and is one of the most popular types, and the grades are within what we typically recommend buyers look for.

The prices at Clean Origin range from $562 to $985, making them as cheap as Ritani and cheaper than any other lab diamond jeweler we have compared with.

While we would not recommend every diamond in the above selection, most are excellent and recommendable. However, always study the 360-degree diamond images and certificates since lab diamond grading is somewhat subjective and can vary.

See more in our price comparison for 1-carat lab diamonds, 2-carat lab diamonds, and all the way to 6-carat lab diamonds, and you’ll find that Clean Origin is consistently among the cheapest of the lab-grown diamond jewelers we recommend. And significantly cheaper than any mall jeweler or mined diamond seller.

Diamond jewelry prices

When it comes to lab diamond jewelry, our Clean Origin review finds that it also consistently ranks among the cheapest for any lab diamond jewelry. In fact, in most cases, Clean Origin’s lab diamond jewelry prices are unbeatable.

Comparing the prices of lab-created diamond stud earrings, the most popular lab diamond jewelry apart from lab diamond engagement rings shows how low the prices at Clean Origin are. A pair of 1-carat total weight lab diamond stud earrings are sold for less than $800, which you would easily pay several thousand for at other jewelers.

Similarly, the normally prohibitively expensive but impossibly elegant diamond tennis bracelet can be acquired for less than $1,000, and a 3-carat tw. version for less than $1,500. If you look at places such as Zales, Kay, Jared, Helzberg, or Diamonds Direct, you’ll often pay 2-3 times as much! And 5-6 times more if you go for mined diamonds.

You should note, however, that the quality of pre-set diamonds varies and that we recommend that you customize any jewelry. That means picking the loose diamonds from Clean Origin’s vast selection and pairing them with whatever setting you had your eyes set on.

Luckily, as we’ll get into later, Clean Origin’s friendly customer support will gladly help you find suitable diamonds. We have found that their support is extremely patient and helpful. And, importantly, they do not try to pressure you to pick more expensive diamonds but will recommend diamonds that actually are the best fit for your needs.

Simply contact Clean Origin’s customer support and ask for their advice on what diamond to pair with, and you’ll get much better diamonds for the money and won’t overpay for a sub-par pre-set quality (more on their customer service later in the Clean Origin review). We also advise that you read our lab diamond buying guide packed with tips for finding the perfect lab-grown diamond.

Clean Origin selection of lab-grown diamonds

Clean Origin exclusively sells lab-grown diamonds, so you don’t have to worry about diamonds being conflict-free (they are) or the carbon footprint (it’s much smaller).

As we have found in this Clean Origin review, their dedication to lab-created diamonds clearly shows. This includes the vastness and quality of their lab diamond selection.

Clean Origin offers an extensive selection of loose stones and ready-to-ship lab-created diamond jewelry. Currently, they have nearly 70,000 lab diamonds available in all possible sizes and shapes.

Loose lab diamond selection on Clean Origin's website found during our Clean Origin review.

The largest selection is of round brilliant diamonds, the most popular diamond shape. But they also offer a big enough selection of fancy-shaped diamonds to ensure everyone can find something for their taste and budget.

The only thing we miss is a broader selection of fancy-colored lab-grown diamonds. While Clean Origin does sell colored diamonds, they are limited to pink, yellow, blue, and green, and the choice is smaller than what we’ve found at James Allen and Brilliant Earth. But the prices are better at Clean Origin!

Clean Origin lab diamond jewelry selection

You can choose between an impressive variety of jewelry settings and pre-set jewelry pieces. You can find both classic diamond jewelry, such as diamond stud earrings and tennis bracelets, and more creative designs and fashionable jewelry.

And while you’ll find more unique diamond jewelry designs at places such as Grown Brilliance, Kimaï, and Vrai, the selection at Clean Origin is broad enough to cover almost anyone’s needs.

In our review of Clean Origin, we have found that they offer an extensive selection of lab diamond jewelry.

As always, we highly recommend picking the jewelry design and setting you prefer and then searching for a diamond that fits your needs.

If you change your mind, you can use their generous 100-day risk-free money-back guarantee to change to another setting – completely free of charge! More on that and their fantastic customer service next in our Clean Origin review.

Clean Origin customer service

In this part of our Clean Origin review, we’ll take a closer look at their customer service and the shopping experience.

Clean Origin has built its company around customer service and ease of doing business. They’re a digital-first direct-to-consumer company, and it shows. The shopping process is made truly simple, and whenever you have any questions, you can just initiate a chat for an immediate response (not a bot!).

You can choose between ready-to-ship jewelry or pick out your own lab-grown diamonds and match them with your favorite setting by choosing between a vast selection of settings of any type, style, and metal imaginable for complete customization and a personal piece of jewelry.

One of the things we like in our Clean Origin review is their diamond ring customization features.

We always recommend choosing your own diamond to go with your preferred setting. This way, you’ll get the exact diamond that fits your needs. And while it can be a daunting task to find the perfect diamond, Clean Origin will guide you through the process. Read more about that next in our Clean Origin review.

We also recommend you learn about the diamond 4Cs and read our lab-grown diamond-buying tips.

Clean Origin shopping experience

Like other diamond sellers who have embraced the technological possibilities of showcasing diamonds online, Clean Origin offers high-definition 360-degree inspection of all diamonds. While they may not be quite as advanced as the pioneering James Allen, they are among the very best, and most buyers will be delighted with the level of due diligence possible at their site.

Diamond inspection in HD and 360 degree view at Clean Origin's website found during our Clean Origin review.
360-degree and high-definition views of all diamonds are available at, so you can inspect the diamonds in every detail before you purchase.

Below is an example of the 360-degree diamond view. This is a critical part of the diamond inspection and buying process. Make sure that you don’t see any significant blemishes and inclusions and that the light reflection is vivid and vibrant.

Clean Origin provides 360-degree images/video of all diamonds.

You can also assess the dimensions of the diamond, such as the width, table, depth, girdle, and culet. However, these are better studied with the diamond diagram, which Clean Origin also provides for all diamonds.

In our Clean Origin review, we've found that Clean Origin offers diagrams of all diamonds.
You can find the dimensions of all diamonds at Clean Origin on the product page.

As part of the diamond inspection process and your due diligence, you would also study the diamond certificate, which we’ll get into next in our Clean Origin review.

Clean Origin diamond certification

Lab-grown diamonds are graded and certified by the same laboratories and grading institutions as mined diamonds. And the certification is performed using the exact same standards and procedures. Therefore, you can rest assured that your lab-created diamond is exactly the same as a mined diamond, and you can compare them like-for-like using the 4C grading system (read more about the 4Cs here).

All diamonds purchased through Clean Origin are graded and certified by the best diamond labs. Most grading is carried out by the renowned International Gemological Institute, the leading institute for lab-grown diamonds headquartered in the diamond capital of Antwerp, Belgium.

This means you can trust their diamond grading. And always remember to choose the highest diamond cut grade, which for IGI is ideal.

Clean Origin uses leading diamond grading institutes like the International Gemological Institute and GCAL - Clean Origin review

It’s very easy to find the lab diamond certificates at Clean Origin, which are accessible right from the diamond product detail page for all diamonds.

In our review of Clean Origin, we have found that the diamond certificates are readily available from the product page.

The diamond certificate will show you key information about the diamond, including, in many cases, the presence, type, and placement of inclusions and blemishes.

In our review of Clean Origin, we have found that the diamond certificates are readily available and often includes a diamond clarity chart.
The clarity diagram shows where any blemishes and inclusions are located and their type.

Clean Origin customer service

As part of our lab diamond jeweler reviews, we always test customer service. This includes interactions, the professionalism of the advice given, responsiveness, friendliness, as well as return policies and shipping. And we’ve done the same for this Clean Origin review.

Responsive customer support

If you are less familiar with buying and inspecting diamonds, you can get help from the qualified customer service team at Clean Origin, and that’s what we’ll review next.

It’s very easy to contact Clean Origin via chat, email, or phone, and they are incredibly responsive regardless of the inquiry type. We recommend using the chat or email option when deciding on a diamond since you’ll get an immediate reply and have time to read through the responses in detail after your interaction (buying a diamond requires thoughtful consideration).

Clean Origin is adamant that all your questions are answered and that you’re satisfied with their support. Speaking or chatting with Clean Origin’s representatives is a true pleasure, and we’ve rarely encountered such friendly, knowledgeable, and customer-centric service. And we’ve interacted with a lot of jeweler customer services!

Professional guidance

Clean Origin’s customer service is staffed by diamond experts, and they are ready to guide you expertly through the buying process. In our experience, they are highly transparent, do not try to push more expensive stones, and even recommend cheaper diamonds when appropriate.

It’s evident that they are true experts at their trade and possess deep-diamond knowledge. We were particularly impressed by their patience and friendliness, how no ask was too big, and how they strived to make the customer happy.

Virtual appointments

Clean Origin now also offers virtual appointments, similar to James Allen, Ritani, Grown Brilliance, Brilliant Earth, and With Clarity.

This dramatically improves the diamond shopping experience, particularly if you need help finding the exact diamond for you and perhaps a lab-grown diamond engagement ring.

Clean Origin offers virtual appointments to help you find the right diamond for you - Clean Origin review.
In our review of Clean Origin, we've found that it's very easy to book a virtual appointment.

As noted above, Clean Origin’s professional support is exceptionally honest and, unlike what you may have experienced at a physical jeweler, wants the best for you. They’ll even advise you against a more expensive diamond if it’s not right for you!

Clean Origin free shipping and free returns

Clean Origin offers free FedEx Overnight shipping on every order and free return shipping on all orders (currently US only). Orders are shipped securely overnight following a 7-10 day production time, but they also offer flexible delivery options to avoid ruining any surprises. Shipping is fully insured, and order delivery must be signed by the receiver.

Returns are entirely hassle-free using the same premium standard of shipping with the option to send through a FedEx-staffed shipping station if you need any assistance. We tested Clean Origin’s return process, and it’s effortless and straightforward.

Clean Origin’s 100-day money-back guarantee

Clean Origin offers a very generous risk-free 100-day money-back guarantee. Not only do they provide a full refund, but you can also choose to exchange your purchase for another setting or stone while relying on their expert guidance throughout the process.

You should always ensure that any diamond purchase includes risk-free and easy returns. Our best-rated lab diamond jewelers offer at least a 30-day return period. But Clean Origin outdoes them all by offering a staggering 100-day return period!

Clean Origin environmental impact

Clean Origin devotes much attention to the environmental benefits of lab-grown diamonds versus mined stones. By purchasing lab-created diamonds instead of mined, you avoid disturbing land and decrease mineral waste by more than 6,000%! No animal habitats are disturbed, and growing diamonds in a lab leave no huge holes around (some of which you can see from space).

Energy consumption is 25 times lower, and water consumption is 1/7th of the mined counterparts per diamond carat. Whether it is gold or platinum, even the metal is recycled, keeping the environmental footprint minimal. It’s safe to conclude that buying a lab-grown diamond through Clean Origin instead of a mined diamond is better for the environment.

Lab-grown diamonds from Clean Origin use only 15% water in their production compared to mined diamonds - Clean Origin review.
Only 15% water is used compared to extracting diamonds from mines

The only area where Clean Origin could raise its environmental bar would be to rely solely on renewable energy, as a few producers do. These include Vrai through Diamond Foundry, and what Pandora is aiming for, or the sustainably rated diamonds from Brilliant Earth. In our review of Clean Origin, we would have liked to see a little more commitment to the clean energy cause, but overall Clean Origin scores very high on the sustainability report.

You can read more about all the benefits of lab-grown diamonds here.

Clean Origin human impact

Diamond mining has a poor track record of leaving conflict, human and workers’ rights violations, political turmoil, and conflict in its wake. Mining also harms local communities and brings disease, pollution, and corruption to mining communities, while working deep in mines results in injuries and health-related issues.

Diamonds created in a laboratory have none of those issues, and the human impact is solely positive. In our Clean Origin review, we appreciate and applaud their dedication to setting things right and educating consumers. You can learn more about the benefits of lab-grown diamonds in our in-depth article here.

Our Clean Origin review verdict

Clean Origin review logo summary

In our Clean Origin review, we award them fully 5 stars out of 5 for their unbeatable prices, a massive selection of high-quality lab-grown diamonds, and stellar customer service. We cannot recommend them highly enough.

This does not change for our updated 2023 review. Clean Origin, together with James Allen and Ritani, is still our favorite jeweler, and we have yet to find competitors with stronger offerings or better prices.

The only possible improvement area would be relying on 100% clean energy (which would also go well with their name) and a more extensive selection of fancy color lab diamonds, but these limitations are negligible.

Our 2023 Clean Origin review again gives Clean Origin a perfect score, and our final verdict is an exceptional 5 out of 5 stars.

Clean Origin customer reviews

Customers agree with us and leave rave reviews all over the internet, and their sentiments are closely aligned with our Clean Origin review. So you can feel confident in purchasing through Clean Origin.
