Lab-grown diamonds have been expanding in popularity. And unsurprisingly, lab-grown diamonds are now sold on Amazon, too. That’s why we decided to review buying diamonds on Amazon.
But buying lab-grown diamonds and lab diamond jewelry is not the same as shopping for a memory card or Crocs. It’s a little more complicated.
There are a lot of aspects of lab-grown diamonds to be aware of, and if you’re not careful and aware, you’ll end up with a poor-quality diamond and disappointed. That’s why it is critical to learn how to shop for lab-grown diamonds before buying lab-grown diamonds on Amazon.
To help you decide if you should buy a lab-grown diamond or lab diamond jewelry on Amazon, we have reviewed what it’s like to buy lab-grown diamonds there. In this review of lab-grown diamonds on Amazon, we will uncover the potential issues to be aware of when buying lab-grown diamonds on Amazon.
Although Amazon is known for its convenience and endless inventory of products, the process of purchasing lab diamond jewelry is more challenging than most people think. The Amazon platform is not built for selling diamonds, and buying lab-grown diamonds online requires access to key features and information.

We’ll explore problems such as assessing stock or generic photos that may not accurately represent the lab diamond, limited knowledge about the specific lab diamonds used in jewelry pieces, and low-quality lab diamond options available.
Furthermore, we’ll delve into pricing concerns and value for money when purchasing from an online platform like Amazon. Finally, we will touch upon customer service limitations and how they might impact your overall experience when buying lab-grown diamonds on Amazon.

Amazon uses diamond stock photos
When searching for lab-created diamonds on Amazon, you’ll always run into the problem of generic images of lab diamonds or, worse, stock images that may not even be from the retailer or of similar diamonds. This can be pretty problematic for several reasons:
Quality of diamond images
The quality of stock photos used on Amazon often leaves much to be desired. These images are often generic and do not accurately depict the actual appearance or characteristics of a specific lab-grown diamond being sold.
Without access to high-resolution images or videos of the actual lab diamonds being sold, it’s impossible to directly compare different options or ensure that you’re getting the best value for your money.
Lack of diamond information
Stock photos provide very little information about the actual lab-grown diamonds being offered for sale on Amazon. Without detailed images or descriptions, it’s nearly impossible for you to make informed decisions when purchasing these gems online.
Our best-rated places to buy lab-grown diamonds always allow you to pick the actual diamond. They list high-definition images and 360-degree videos of the actual lab-grown diamond you are considering. You’ll also have access to the diamond certificate of the particular lab diamond.
Misleading diamond depictions
In some instances, stock photos may even misrepresent the true nature and quality of a particular lab-grown diamond available on Amazon. As a result, shoppers who rely solely on these images might end up with a product that doesn’t meet their expectations regarding size, color, clarity, or cut.
To avoid disappointment and ensure you’re getting exactly what you want when buying lab-grown diamonds, it’s crucial to have access to accurate visuals and comprehensive information about each gemstone’s specifications and origin – something sorely lacking when browsing through listings featuring only stock imagery.

Overall, the quality of stock photos on Amazon for lab-grown diamonds is lacking and often misleading. With this in mind, it’s important to understand what knowledge of lab diamonds is used when purchasing them online.
Diamond information on Amazon
When shopping for lab-grown diamonds on Amazon, one major concern is the limited information about the diamonds used in the jewelry. We have already touched on this in the previous section of our review of lab-grown diamonds on Amazon, not only the problematic images. As a buyer, you want to ensure that the lab-grown diamond you are buying meets your requirements and is accurately depicted and described.
Limited diamond information
The product descriptions for lab-grown diamond listings on Amazon often lack crucial details such as cut quality, clarity grade, color grade, and even carat weight! This can make it difficult to compare different options or determine if a particular diamond is worth its price tag.

In addition, you cannot see the diamond grading reports (also known as diamond certificates) for lab diamonds on Amazon. These are critical for understanding the quality of the diamond and giving you the certainty that the provided information is correct.
Unclear origin of diamonds
In addition to lacking detailed information about each diamond’s specifications, many listings do not disclose where their lab-grown diamonds are created or how they were created. Knowing this can help you understand more about the quality and ethical standards of diamond creation.

Inability to choose your own diamond at Amazon
Unlike lab-grown diamond jewelers, who allow you to choose individual loose lab-grown diamonds based on specific criteria like cut, clarity, color, and carat weight (James Allen or Ritani, for example), Amazon does not offer this level of personalization when buying pre-set jewelry pieces with lab-created stones.
We always recommend picking the diamond you want from the jeweler’s inventory of loose lab diamonds. That’s because you’ll be able to find the best diamond for your specific needs (e.g., a lower color grade for a piece set in gold). And even more importantly, jewelers tend to use lower-quality diamonds in pre-set jewelry. Later this review of buying lab-grown diamonds on Amazon will look closer at the lab diamond quality.
Since you cannot choose your own lab-grown diamond on Amazon, there is no guarantee that the diamond used in your jewelry piece selected will meet your criteria or expectations.
In summary, when buying lab-grown diamonds on Amazon, customers are faced with limited information about the actual stones being used and an inability to select their preferred diamond based on specific criteria. These factors contribute to uncertainty regarding overall quality and value for money.
Lab-grown diamond quality on Amazon
Unfortunately, many lab-grown diamonds sold on Amazon suffer from poor cut quality, low clarity and color grades, and limited carat weight options.
Poor diamond cut quality.
The cut of a diamond is critical for determining its overall beauty and brilliance. A well-cut diamond will maximize light return and create an eye-catching sparkle that distinguishes it from lesser-quality stones. In fact, when considering brilliant-shaped lab-grown diamonds, you should value the diamond cut grade over anything else!

Unfortunately, when purchasing lab-grown diamonds on Amazon, it is difficult to ascertain the quality of the cut due to a lack of information about the diamond cut grade, facets, and dimensions.
Some listings refer to diamond cut grades as “excellent” or “ideal”, which are the highest cut grades at GIA and IGI, respectively. However, in most cases, these claims are not backed up by independent lab diamond grading or certificates without providing factual information about the specific proportions or angles of the diamond’s facets.

This lack of transparency makes it difficult to know if you’re getting a truly well-cut stone or just an average one with an alleged cut grade.
Poor clarity and color grades
Beyond cut quality, other factors such as clarity and color also play significant roles in determining a diamond’s value and appearance. Unfortunately, when browsing through lab-grown diamond listings on Amazon, you may notice vague descriptions regarding these important attributes – sometimes even missing entirely.
Diamond clarity is determined by the presence (or absence) of internal flaws known as inclusions and blemishes. These can impact how much light passes through your gemstone unimpeded by imperfections within its structure.
Diamond color grades (in colorless diamonds) tell you if a hue, typically yellowish, is present in the diamond and to what extent. For fancy-colored lab diamonds, it’s a little different, but these, too, are graded.
Without proper grading information from a reputable gemological laboratory, such as the Gemological Institute of America (GIA) or the International Gemological Institute (IGI), it’s difficult to determine if you’re getting a high-quality lab-grown diamond or one with noticeable inclusions and color tinting.
Low carat-weight options
Another drawback when buying lab-grown diamonds on Amazon is the limited range of carat weights. While some larger lab diamonds are available, many listings only offer smaller sizes that may not meet your needs, particularly for engagement rings or other significant jewelry pieces.
This lack of variety can make it hard to find the perfect diamond. In contrast, lab-grown diamond jewelers often provide much more extensive selections and customization options so you can choose the exact size, shape, and diamond grades that suit your needs best.
Purchasing a low-grade diamond can be an expensive blunder, so it’s essential to consider cost and value for money when selecting one. When shopping on Amazon, you should consider factors such as transparency in pricing, quality assurance guarantees, and carat weight options before deciding which diamond is right for you.
When buying lab-grown diamonds on Amazon, it’s essential to be aware of the potential drawbacks such as poor cut quality, low clarity and color grades, and limited carat weight options. Without proper grading information from a reputable gemological laboratory like GIA or IGI, it’s impossible to know what you are buying.
Lab-grown diamond prices on Amazon
In our review of lab diamond buying on Amazon, we have so far learned that there are issues with lab diamond images, inadequate or misleading information, and poor diamond quality. But what about the prices for lab-grown diamonds on Amazon? Let’s look into that next.
Having read through the above sections of our assessment of buying lab diamonds on Amazon, it may not surprise that prices, too, are not fantastic. Here are the reasons.
Prices for lab-grown diamonds on Amazon are high.
Lab-grown diamonds on Amazon are often higher than those from reputable lab diamond jewelers. Particularly when considering the usually low quality and lack of quality assurance.
This could be due to various reasons, such as higher fees charged by the platform or sellers trying to compensate for lower sales volumes by increasing prices, regardless of why, you’ll likely end up paying a premium without receiving any additional benefits in return.
Lab diamond prices on Amazon are not transparent.
In addition to lab diamonds often being more expensive on Amazon, there is a lack of transparency when pricing on Amazon listings. As highlighted before, many sellers fail to list detailed diamond quality data, making it difficult for shoppers to assess lab-grown diamond prices on Amazon accurately.
Lacking authenticity and certificates
As we have also mentioned above, a significant concern when buying lab-grown diamonds on Amazon is the lack of guarantee regarding quality and authenticity. While some sellers may claim to offer certified diamonds, there’s no way for customers to verify this information easily.
In contrast, reputable online diamond jewelers in lab-grown diamonds always provide detailed certification from well-known laboratories like IGI or GIA, ensuring that you receive accurate and independent information about the diamonds you are considering.
While Amazon might seem like a convenient option for purchasing lab-grown diamond jewelry, it falls short in terms of pricing transparency and value for money compared to other places. You should be cautious when considering buying on the platform due to potentially higher prices, vague product descriptions, and a lack of verifiable independent diamond certificates.
Amazon diamond customer service and support
Unfortunately, when purchasing lab-grown diamonds on Amazon, you may also encounter issues with their customer service that can negatively impact your overall experience.
Limited customer service knowledge about lab-grown diamonds
The availability of knowledgeable customer service representatives specializing in lab-grown diamonds is limited on Amazon. As a result, getting accurate information about diamonds or addressing any concerns related to your purchase becomes challenging. In contrast, dedicated lab-grown diamond retailers usually offer personalized assistance from experts in the field, including virtual appointments with gemologists.
Difficulty obtaining refunds
If you’re unsatisfied with your purchase of a lab-grown diamond from Amazon due to poor quality or misrepresentation of the product details, obtaining a refund might prove difficult.
Different sellers have varying return policies. For that reason, you should always read the return policies carefully before making a purchase.
In contrast, our highest-rated lab diamond jewelers all offer more straightforward return processes and better guarantees for their products as they understand how important trust and satisfaction are in this industry.
Purchasing high-quality lab-grown diamonds requires thorough research and attention to detail – which may not be possible on shopping platforms like Amazon. To ensure you get the best value for your money and a satisfying shopping experience, consider exploring other lab-grown diamond retailers that specialize in providing high-quality diamonds, personalized customer service, and transparent pricing.
So, should you buy diamonds on Amazon?
Overall, buying lab-grown diamonds on Amazon is a risky proposition. Finding the perfect diamond is near impossible, and even if you do, there is no certainty of quality or value. Furthermore, stock photos are used instead of actual images of lab diamonds, and information about the specific lab diamonds used is limited. That’s why we don’t think you should be buying a lab-grown diamond on Amazon. Instead, buy your lab-created diamonds from a jeweler, not a bookseller.
Reputable lab-grown diamond jewelers on Amazon
While we highly discourage buying lab-grown diamonds on Amazon, there are a few reputable lab-grown diamond sellers on Amazon.

Grown Brilliance
Grown Brilliance started mainly selling on platforms such as Amazon but has since graduated to become a fully-fledged lab-grown diamond jeweler selling through its own high-quality and feature-rich website.

Amazon vs. Jeweler’s website?
Should you buy directly from them or through Amazon? Of course, you could buy lab-grown diamonds on Amazon from reputable sellers such as the above, but make sure you reach out to them first. And consider buying directly from their own website, where you can often pick the exact and actual diamonds, see HD diamond images, and access diamond certificates.
