  • Wedding bands: Find both women's and men's wedding bands in either plain metal or set with lab diamonds.

Clean Origin Pricing + Comparisons

Among other retailers, Clean Origin offers the best pricing for lab diamonds by a long shot. You can expect to pay around $1,000 - $1,300 for a good quality, 1-carat diamond.

Here are some real pricing comparisons against James Allen and Brilliant Earth (two other popular lab diamond retailers).*

Clean OriginJames Allen Brilliant Earth
1.0 carat, Round, H, VS1, Ideal$1,204$1,820$1,510
1.0 carat, Princess, G, VS1$1,376$1,880$1,990

*Pricing information from in-stock diamonds as of 10/28/21. Examples shown are the lowest-priced available diamonds from each retailer that fit the specs. We chose IGI certified diamonds for a fair comparison.

If you're looking to maximize budget, Clean Origin should definitely be on your consideration list. With the cheaper diamond pricing, you can get a larger stone or choose a more luxe setting.

Does Clean Origin ever have sales?
No, Clean Origin doesn't have sales, because they always offer the most competitive prices right from the start. There's also no price match program, as their prices are already lower than other retailers.

But Clean Origin does offer discounts for government, military, nurses, responders, students, and teachers.

Website Experience

Clean Origin's website is very user-friendly. It's easy to search for the diamond you want by setting filters for carat, color, clarity, cut, budget, and more.

The only downside is that when you click on a diamond, you don't get an actual photo of the diamond. You have to click on the 360 button, which opens up a 360 Viewer on another page.

Not being able to view the diamonds on the page itself is inconvenient. The 360 Viewer can be slow to open. It detracts from the website experience, but isn't a dealbreaker.

After you pick the diamond, you can add it to an engagement ring (or vice versa). All the settings have stunning 360-views that show you what it looks like from every angle.

You'll get a breakdown like this (below) showing you the final price and selections. You can make changes if you wish.

Overall, despite some kinks, Clean Origin's website is intuitive and helps you navigate the ring design process.

Downsides of Clean Origin

Clean Origin is a top choice for lab diamonds, but here are some downsides to be aware of.

Not all diamonds have a real photo
A lot of diamonds don't have a real photo or 360 video. If you find a diamond with the right price and specs, you may need to buy it blind.

All Clean Origin's diamonds are prescreened to be eye-clean, but it could still be nerve-wracking to buy a diamond without even a photo.

Pricier settings
Clean Origin's setting prices tend to be higher compared to James Allen. For example, the most basic solitaire ring costs $535 on Clean Origin, while James Allen has a similar one for $240.

But with the low diamond pricing, you should still be able to save overall.

No upgrade/buy-back
Sometimes people start off with a smaller, cheaper diamond and upgrade it later when their finances are more stable.

But because lab diamonds don't really have resale value, Clean Origin does not offer an upgrade or buy-back program.

If you think you may want a bigger diamond later on, just keep in mind that you won't be able to get some money back from your lab diamond ring to help offset the cost.

Not global
As of now, Clean Origin only ships to the United States, Canada, United Kingdom, and Australia.

Returns / Resize / Warranty

  • 100-day returns: You get free returns within 100 days, no questions asked. This is the most generous return policy we've seen among online diamond retailers.

    You need to first get a return shipping authorization code from Clean Origin. You must ship your return within 7 days. Returns must include all documentation/certificates and be in original condition.

    Clean Origin will provide a FedEx shipping label (for U.S. customers only).

  • 100-day resizing: If you accidentally got the wrong size, you get 1 free resizing within 100 days of the original shipment date. Clean Origin will also pay for the shipping both ways. Some styles, like eternity rings, cannot be resized.

  • Warranty: Clean Origin offers a lifetime warranty against manufacturer defects. This means if the problem is from when they made the ring, they will repair or replace it. But it does not cover damage from poor care or normal wear and tear.

  • Free shipping. U.S. and Canada customers get free FedEx 2-business day delivery. Return shipping is also free. UK and Australia customers get free fast international shipping. All shipments are 100% insured.

Financing & Discounts

Before checkout, you have options to select financing and/or check for discounts.

If you don't have enough for the entire ring right now, you can split up your purchase. Clean Origin offers 6, 12, 18, or 24-month financing with Affirm (depending on the price). It takes just minutes to get a decision on approval.

Affirm will show you the interest rate and monthly payment so you know exactly what you'll be paying.

Clean Origin also offers discounts for government, active-duty military and veterans, nurses, responders, students, and teachers. You get $100 off any engagement ring purchase that includes a lab diamond. It's a pretty sweet perk to thank you for all the hard work you do.

You must sign in with to confirm your status. After verification, your discount code will be activated.

How it Compares

There may be other lab diamond retailers you're considering for the big purchase. Here's how Clean Origin compares against other popular brands.

Clean Origin vs. Brilliant Earth

Brilliant Earth is the leading ethical diamond retailer. It offers both natural diamonds from ethical mines and lab-grown diamonds.

Just like Clean Origin, all Brilliant Earth rings are also made from recycled metal. It also has ethical gemstones if you're looking for a less traditional ring.

Another thing that really sets Brilliant Earth apart is their gorgeous ring designs. It has a lot of nature- and vintage-inspired settings. If you really fall in love with a Brilliant Earth setting, that may seal the deal.

Brilliant Earth also donates a portion of their profits to improve mining communities in Africa. Plus, it contributes to Tropical Rainforest Conservation in Brazil. This may appeal to you if you want to do good with your purchase, even if diamond prices are slightly higher.

Clean Origin vs. James Allen

James Allen is one of our top recommended retailers for its great pricing and large variety. It has a large selection of natural diamonds, lab diamonds, gemstones, and settings.

James Allen's lab diamond prices are not the lowest on the market. But there are other perks to make up for it.

The settings tend to be a little cheaper (plus, they have sales throughout the year). There are over 600 different ring styles on James Allen, so you're more likely to find something you really love. It even has designer rings by Verragio, Danhov, and more.

You also get a lifetime of free service, which could very well make up for the higher price. James Allen's warranty covers cleaning, polishing, prong tightening, rhodium plating, and other maintenance and repairs. It's even partnered with Jared, so you can get these services done in person.

Common Questions

Are lab diamonds fake?
Lab diamonds are very much real diamonds. They have the exact same properties as earth-mined diamonds. The only difference is how they're made. Lab diamonds are made in labs that replicate the natural creation process.

Which grading lab is the best?
Clean Origin offers lab diamonds graded by GIA, IGI, and GCAL. GIA is widely accepted as the best lab because it has the highest grading standards and consistency. Diamonds graded by GIA are slightly more expensive because it costs more to get certification from them.

Most lab diamonds are graded by IGI and GCAL, since lab diamonds are not as valuable. In this case, IGI is probably the most reliable lab certification for lab diamonds.

Do lab diamonds last?
A lab diamond will last just as long as a real diamond. They have the same hardness - 10 on the Mohs hardness scale, which is the hardest gemstone available. You don't have to worry about your lab diamond getting scratched and cloudy.

Do lab diamonds hold value?
This is one downside to lab diamonds. Since they are mass-produced in labs, the resale value is weak. There is no historical or rareness value. Since Clean Origin doesn't have a trade-up/buy-back program, your lab engagement ring is for keeps.

Bottom Line

Clean Origin is a top choice if you're looking for a lab diamond engagement ring. It offers high-quality stones at some of the lowest prices on the market.

All their lab diamonds and metals are ethical, so you can feel good about your purchase. Plus, there's a very generous 100-day free returns policy. You can have peace of mind knowing that you're not stuck if you don't 100% love your purchase.
