Clean Origin vs. Ritani: Introduction to Ritani

Since its founding in 1996, Ritani has worked in tandem with the famed jewelers of Julius Klein. Ritani started operating in the diamond retail industry in 2012 and has since developed into one of the top diamond dealers and jewelers online, even bridging the gap between online and physical jewelry stores (more on later).


In addition to wedding bands, engagement rings, diamond jewelry, and fashion jewelry, Ritani sells diamonds that have been mined and diamonds created in a lab. They also provide custom-made jewelry made to order at their New York location.

Clean Origin vs. Ritani: Lab-grown diamond selection

First, we’ll compare Clean Origin vs. Ritani’s diamond inventory and see which has the better diamond and jewelry selection, comparing both quality and quantity.

Clean Origin diamond quality and inventory

A wide range of premium lab-grown diamonds is available from Clean Origin—approximately 30,000 loose lab-grown diamonds in various forms, dimensions, and quality. Unfortunately, there were only 13 matches in their inventory when we looked for our reference diamond (see below). We wish they had a more extensive selection; however, expanding our search shows that Clean Origin, in fact, has a vast diamond inventory, and almost all are of exceptional quality.

Our reference diamond is a round brilliant-cut lab-grown diamond weighing between 0.93 and 1.07 carats. The reference diamond clarity is in the range of VS1 to VS2 and with a diamond color grade of I to J. The lab diamond cut grade is always the very best. For most lab-grown diamonds (certified by IGI) that grade is Ideal.

Additionally, Clean Origin offers a significant selection of ready-to-ship jewelry designs in various traditional and contemporary styles.

Ritani diamond quality and inventory

Ritani offers one of the most impressive collections of high-quality diamonds, both mined and lab-grown. The inventory of Ritani comprises 97,000 loose lab diamonds and over 165,000 mined diamonds – one of the largest we’ve seen anywhere.

We discovered 118 lab diamonds that corresponded to the details of our reference stone (0.93-1.07ct, I-J color, VS1-VS2 clarity, and ideal cut). Unfortunately, compared to what we found in our comprehensive Ritani review from 2023, there are fewer matches. However, Ritani’s extensive collection still astounded us, and there is a significant chance that you will be able to locate the ideal diamond for you.

Ritani enables you to design your diamond jewelry, much like all the top suppliers of lab-grown diamonds. By selecting a diamond from their massive inventory of loose diamonds, you may, for instance, create a unique set of diamond earrings or a diamond pendant. This is fantastic because you’ll be able to get the ideal diamond for your requirements while staying within your budget. Since pre-set diamond jewelry frequently pairs with inferior diamonds, we always advise choosing your diamond and designing your jewelry.

Clean Origin vs. Ritani: Diamond price comparison

Next, in our Clean Origin vs. Ritani comparison, we look at the diamond and jewelry prices of Clean Origin and Ritani. We’ll start with Clean Origin first.

Clean Origin diamond prices

Clean Origin has some of the most affordable and competitive pricing for loose lab-grown diamonds. In terms of pricing, only Ritani offers the same excellent prices as Clean Origin (see more below and in our review of Ritani’s prices). Consequently, when you purchase at Clean Origin, you’ll save a lot of money!

The cost of our reference diamond (see above) at Clean Origin ranges between $635 and $1,170. These lab-grown diamonds are among the most reasonably priced ones we’ve seen anywhere, based on comparisons with other diamond shops.

Clean Origin offers pre-set diamond jewelry at very reasonable prices, too. For instance, a 1/2 carat (tw) solitaire pendant goes for $695, which is less expensive than similar-sized but better-cut graded diamonds from Ritani ($1,356) or James Allen ($1070). In this case, as we’ll note below, we recommend going with the better-cut pendant from Ritani because you always want to go for the highest possible diamond cut.

But instead of purchasing pre-made diamond jewelry, we highly recommend that you pair your diamond jewelry by choosing the diamond from the seller’s inventory of loose diamonds. You’ll get a much better diamond if you do it this way. As it turns out, Clean Origin is one of the best places to create your jewelry.

Ritani diamond prices

As we documented in our Ritani review, they offer some of the market’s best-priced lab-grown diamonds; only Clean Origin has similar low prices.

Our reference diamond at Ritani is priced between $519 to $1251. This is substantially less costly than every other diamond vendor (bar Clean Origin). Moreover, because of their vertical integration, they can maintain their pricing so low. Learn why Ritani’s prices are so low.

Ritani will also recommend other diamonds that are a better choice (even if they are cheaper). The lowest prices from Ritani sometimes surpass those from Clean Origin, the other market leader in diamond prices.

Ritani’s pre-set jewelry costs are the same as James Allen’s and its closest competitors. But, a key difference is that Ritani exclusively uses diamonds with the highest cut grades (generally rated Ideal when graded by IGI).

As a result, Ritani’s ready-to-ship pre-set jewelry frequently offers significantly greater value than its rivals, including even top-rated James Allen, Brilliant Earth, and Clean Origin.

Summary of Clean Origin vs. Ritani diamond prices

In conclusion, there is not much difference between Clean Origin and Ritani’s pricing. However, when contrasting the costs of pre-set jewelry versus loose lab-grown diamonds, Ritani outperforms Clean Origin slightly due to the better diamond quality, while the prices of their loose diamonds are the same when adjusting for diamond quality. See the price examples below.

The Clean Origin shopping experience

Additionally, Clean Origin provides live chat, phone, and email support from diamond professionals. Each Clean Origin customer care team member has at least five years of expertise in the diamond business and has received the necessary training to assist you in selecting the ideal diamond.

The features aren’t all the way as advanced as at James Allen, but they’re very close and very good. In addition, you can visit Clean Origin’s store in Dallas or, if you’re not in the area, set up a video chat with them to walk you through the diamond-buying process.

The Ritani shopping experience

With Ritani, purchasing diamonds is relatively straightforward. They make all the information easily accessible and understandable, thus lessening the uncertainty of the purchase process. Because of this, Ritani is a breeze for first-time purchasers or those who don’t have much time to spend on diamond purchases.

Ritani provides stunning diamond grading features, high-definition photos, and 360-degree videos of its diamond jewels. As a result, assessing and contrasting diamonds is straightforward.

Clean Origin vs. Ritani: Ritani shopping experience.

One thing Ritani does to make the process even simpler is label diamonds that are fantastic deals. They offer options for you to think about and recommend the best stones in terms of value and quality. The proposed diamond is usually outstanding and worth taking into account.

The pricing transparency of Ritani is another critical feature. Ritani’s markup, expenses, and diamond purchase price are all readily visible! That is exceptionally honest and transparent. We wish that every diamond jeweler shared this.

Along with first-rate phone and email help, the live chat feature runs without a hitch. Additionally, you may speak with licensed and independent gemologists who can help you find the perfect diamond. We have found that they are indeed objective and fair, and given their highly transparent prices, their recommendations are trustworthy.

Ritani doesn’t have its own showrooms, but you may pick up your jewelry and try it on at a WeWork location participating in the program or a Ritani-partnered jewelry store. This is a fantastic option for anyone who wishes to physically inspect the diamond before making a purchase.

Next, see how the shopping experience of Clean Origin stacks up to Ritani’s.

Clean Origin vs. Ritani: Sustainability

As the ethical and sustainable diamond choice, just by selling lab-grown diamonds, Clean Origin and Ritani are great sustainable jeweler options. While Ritani also sells mined diamonds, Clean Origin focuses entirely on lab-created diamonds.

If sustainability is the key differentiator for you, consider Brilliant Earth or Vrai, the two leading sellers of 100% sustainable diamonds (and compare Brilliant Earth vs. Vrai).

Clean Origin sustainability

Clean Origin was started to promote sustainability and ethical diamond options. As a result, they have consistently advocated for lab-grown diamonds over mined ones since they are more environmentally friendly.

Additionally, Clean Origin guarantees that it will plant a tree for every dollar spent, and all of the company’s metals, including platinum, white, yellow, and rose gold, are recycled.

Ritani sustainability

Unlike many jewelers that sell mined diamonds, as Ritani does, they provide a wide variety of lab-grown diamonds. As a result, Ritani also offers a wealth of instructive information regarding the sustainable advantages of lab-created diamonds.

It would be wonderful if Ritani provided the same level of diamond sustainability as we saw in our Brilliant Earth review. However, given that lab-grown diamonds are already the more ethically and environmentally responsible alternative to mined diamonds, Ritani’s sustainability profile is already excellent.

Clean Origin vs. Ritani: Shipping and Returns

In addition to free returns within 30 days, Ritani provides free delivery on all items shipped in the United States via FedEx Priority Overnight (US) and Express shipping (Canada). Similarly, every domestic US order from Clean Origin comes with free FedEx expedited shipping that is fully insured.

Clean Origin’s generous 100-day free return policy, however, cannot be matched by Ritani, which offers a great but more customary 30 days of free return.

Both Ritani and Clean Origin’s customer service are outstanding, and among the best, we’ve encountered. Except for a few advanced features, they are as good as those of the also highly-rated James Allen.

Both Clean Origin and Ritani provide an extensive range of high-quality and low-priced loose diamonds that may be used to create custom jewelry. In addition, it’s possible to create most jewelry types online yourself. At the same time, both Clean Origin and Ritani require that you speak with customer support in some cases, such as if you want to use smaller diamonds or create a jewelry style that is not currently supported. Luckily, it’s very easy; just send a chat message.

Ritani does have a slight edge over Clean Origin when it comes to customization. They generally are a little more flexible and allow a broader range of diamond stones to be used in their settings. So if you’re looking for customization, consider Ritani first.

Where Clean Origin stands out is with its very generous 100-day return period. It’s the best and most flexible return policy we have seen among all jewelers. So if an exceptionally long return policy is essential to you, start with Clean Origin.

But it’s almost too close to call, and we highly recommend both Clean Origin and Ritani as some of the best places to buy lab-grown diamonds online.

Ritani is a little better than Clean Origin when it comes to jewelry customization, where Ritani is more flexible. Clean Origin and Ritani both offer the lowest prices on the highest quality diamonds, the best customer service, and buying experience, and we highly recommend both diamond jewelers.
