Best Places to Buy Lab-Grown Diamond Rings

Purchasing an exquisite ring may not be as expensive as you think. In recent years, lab-grown diamonds have been soaring in popularity and declining in price.

Lab-grown diamonds are indistinguishable from mined diamonds, last just as long, and can be set in any piece of jewelry – but at a significantly more affordable price. And perhaps most compellingly, they can be created in labs using renewable energy without any of the negative consequences of the mining industry, such as unfair labor practices, environmental degradation, and pollution. 

Numerous well-known retailers specialize in lab-grown diamond rings and offer various sizes, styles, colors, and cuts. Here are some of the best places to buy lab-grown diamond rings. The high-quality lab-grown diamonds they offer are just as beautiful and brilliant as any natural diamond – and you’re likely to be pleasantly surprised at what you can afford when you consider a lab-grown diamond ring.

The diamonds on (both natural and lab-grown) have been graded for clarity by the Gemological Institute of America (GIA). These grades range from I1 (included 1), in which some inclusions (slight internal imperfections) may be visible to the naked eye, all the way up to FL (flawless), in which the diamond is completely free from internal and external flaws. On the website, it’s easy to filter diamonds based on the clarity you want.

Like earth-created diamonds, most lab-grown diamonds have a slightly yellowish color. Thus, they are rated based on their proximity to being colorless, with totally colorless diamonds having the top color grade and the most expensive. Color is more visible with larger stones. James Allen offers lab-grown diamonds with color grades from J (a slight color visible in diamonds over 1 carat) to D (totally colorless). James Allen also has a wide range of fancy color diamonds in stunning hues such as yellow, pink, green, orange, and black, all rated for their color intensity.


James Allen offers the same cuts for lab-grown and natural diamonds. The quality of the cut determines how well the diamond reflects light, which defines its overall sparkle and brilliance. Customers can browse lab-grown diamonds in Good, Very Good, Ideal, and True Hearts cuts on the James Allen website. They can also find diamonds in the classic shapes – round, princess, cushion, marquise, pear, oval, etc.


James Allen offers diamonds of practically every size and weight. Lab-grown diamonds are sized in the same way as natural diamonds, in carat weight and millimeters. On their website, available lab-grown diamonds range from 0.3 carats to stones that are more than 6 carats. James Allen offers natural diamonds of over 20 carats for customers looking for a colossal stone. 


As with natural diamonds, the price of a lab-grown diamond depends on a range of factors, including cut, clarity, color, size, and shape. There is a vast range of prices available on the James Allen website. For a 0.30 carat loose round diamond, prices start at around $270, up to over $71,000 for a 5.65 carat diamond. However, many customers will want their stones set in a ring rather than buy a loose diamond. The type of metal and the setting style also affect the price (i.e., white gold vs. platinum, solitaire vs. three-stone). For lab-grown diamonds with excellent cut and clarity ratings, a 1–carat round-cut white gold solitaire costs around $1,700. 

Special Services

The James Allen website offers users an easy way to find the perfect diamond and design their own ring or another piece of jewelry.

Brilliant Earth sells natural and lab-created diamonds with clarity grades ranging from SI2 (semi included 2) to FL (flawless). Diamonds at the lower end of the scale have flaws visible under 10x magnification and may be visible with the naked eye. Very very slightly included, internally flawless, and flawless diamonds have almost no visible inclusions and are correspondingly more expensive.


The color options for Brilliant Earth’s lab-grown diamonds range from J (near colorless) to D (completely colorless). Diamonds closer to the colorless side of the spectrum are rare and are thus more expensive but allow the maximum amount of light to pass through for intense sparkle and fire. Brilliant Earth has a relatively small selection of yellow, pink, and blue diamonds, which are natural instead of lab-grown.

Brilliant Earth’s lab-grown diamonds have the same range of cut quality as its natural diamonds. There is no limitation on the cut quality of a lab-grown diamond. Brilliant Earth’s inventory includes Good, Very Good, Ideal, and Super Ideal cuts, with prices increasing in line with the quality of the cut. Only 3% of jewelry-grade diamonds have the symmetry, uniformity of facets, brilliance, and light reflection properties to earn a rating of Ideal or above. The vast majority of Brilliant Earth’s lab-grown diamonds are rated Ideal or Super Ideal.


The larger lab-grown diamonds stocked by Brilliant Earth are just as high in quality as their smaller lab-grown diamonds, so customers can choose a stone from a vast range of weights and sizes. Brilliant Earth advertises lab-grown diamonds ranging from 0.26 carats to more than 16 carats. 


Customers can design their own rings by selecting the shape, cut, size, clarity, and setting type that they want. As you would expect, there is a vast range of prices for diamond rings. Loose lab-grown diamonds range in price from $260 to $210,000. Because each stone and setting is unique, no two Brilliant Earth rings are unique, so they are priced accordingly. For a 1–carat round-cut white gold solitaire with a high cut and clarity rating, you’re likely to find prices in the $1,800 range. 

Special Services

Brilliant Earth sets itself apart by focusing on ethical and sustainable diamonds and pledges to be carbon neutral. In addition to their lab-grown diamonds, all of their natural diamonds are “beyond conflict-free,” so they have met higher standards for labor practices and environmental sustainability. Customers can virtually “try on” engagement rings by uploading a photo of their hand and then customizing their ring. Brilliant Earth offers flexibility by allowing customers to design every aspect of their jewelry or choose an existing style.

Many people enjoyed meeting with a diamond specialist over Zoom from the comfort of their own home and had fun “trying on” their rings virtually.

Brilliant Earth Pros

  • In addition to its lab-grown diamonds, Brilliant Earth has a significant focus on transparency, environmental stewardship, and ethical sourcing of natural diamonds.
  • Website users can go beyond the basics of cut, clarity, and carat by using additional filters such as symmetry, polish, depth%, and fluorescence to narrow down their search. 
  • Customers can design their own rings with the help of multiple filters, choosing from a range of cuts, sizes, settings, and metals. There are also many ready-to-ship jewelry pieces available.
  • IGI, GIA, GCAL, and HRD reports are available for the most knowledgeable shoppers.
  • Customers have plenty of options when it comes to customer service – they can go to a Brilliant Earth store, arrange a free consultation over Zoom, or contact the company via message, email, live chat, or phone. 

Brilliant Earth Cons

  • The user experience when browsing for loose diamonds on the Brilliant Earth website is a little confusing. It’s good for comparing price, cut, clarity, and shape but is not very visual.
  • You can’t zoom in on Brilliant Earth diamonds to the extent of magnification as some other retailers.
  • Brilliant Earth has a smaller selection of colored diamonds than some other retailers, and none of them are lab-grown.
  • Brilliant Earth’s free shipping, returns, and ring resizing policies apply to customers in the US, UK, and Australia – customers in other countries will need to speak to a customer service representative to find out their country-specific policies.

Customers can browse diamonds with clarity grades ranging from SI2 (slightly included 2 – some flaws visible to the naked eye) to FL (flawless) on the GemsNY website. Most customers who want their diamond to be free from visible imperfections will be satisfied with a diamond with a VS1 (very slightly included 1) or VS2 score.

Each lab-grown diamond stocked by GemsNY has a color rating, ranging from K (slight coloration that impacts the amount of light passing through) to D (the highest grade – completely colorless). Gems with higher ratings offer more sparkle, but they are rare and thus significantly more expensive. You can filter the lab-grown diamonds on the GemsNY website by color, as with other characteristics. 

On the other hand, customers who prefer a brightly colored stone may be interested to know GemsNY also stocks a wide range of colored gemstones such as emeralds, rubies, and sapphires. However, these are all natural stones rather than lab-grown gems.


GemsNY’s lab-grown diamonds range in cut quality from Fair to Ideal Plus. Most of the company’s diamonds are on the top end of that scale. There are no limitations on the cut quality of a lab-grown diamond. Likewise, GemsNY offers the same diamond shapes for lab-grown diamonds as natural diamonds. Customers can choose from popular shapes such as round, princess, and oval and more unusual shapes such as marquise, radiant, and heart shapes.


GemsNY carat

Every diamond on the GemsNY website has a precise carat size, which measures its weight and is a good predictor of the stone’s overall size. The most petite lab-grown diamonds sold by GemsNY are around 0.26 carats, while the largest are over 15 carats. As with natural diamonds, the quality of GemsNY’s lab-grown diamonds is not limited by size or weight. Instead, the diamond’s cut, clarity, and color determine the stone’s quality. 


The lab-grown diamond rings sold by GemsNY tend to be less expensive than comparable jewelry items made with natural diamonds. A vast range of prices is available, from $227 for a 0.25-carat lab-grown diamond to over $85,000 for a 7.06-carat lab-grown diamond. Variations in color, clarity, cut, and the type of setting can significantly impact the ring’s overall price. Overall, though, GemsNY has attractive pricing, with a 1–carat round-cut white gold solitaire with a high cut and clarity rating retailing for around $1,100.

What is a lab-grown diamond?

Lab-grown diamonds are diamonds created in a laboratory or factory rather than being mined. They are “real” diamonds – they have the same appearance and chemical makeup as mined diamonds and are used for both jewelry and industrial purposes. Lab-created diamonds are also known as synthetic or cultured diamonds.

Most natural diamonds were created over a billion years ago with the application of immense heat and pressure deep below the Earth’s surface. Lab-grown diamonds are made using the High Pressure High Temperature system or the more recently discovered Chemical Vapor Deposition process. Thanks to this new technology, the cost to produce a lab-grown diamond has dropped dramatically in the last 20 years.

What’s the difference between lab-grown diamonds and natural diamonds?

Lab-grown and natural diamonds are indistinguishable, both visually and at the molecular level. The difference between them is their origin – they are created in a lab rather than mined from underground. They have the same properties and chemical composition – pure carbon atoms arranged in a crystal structure.

Recent technological advances have eliminated the inconsistencies and discolorations of earlier lab-created diamonds. Special tools such as X-rays and UV light are required to distinguish natural and synthetic diamonds. The Federal Trade Commission considers lab-grown diamonds just as authentic as mined diamonds. 

What to look for in a lab-grown diamond engagement ring?

Lab-grown diamond engagement rings are soaring in popularity, with nearly 70% of millennials saying they would consider buying synthetic diamonds. There are a few things that prospective buyers should know when shopping for a lab-grown diamond engagement ring

As with any significant purchase, it’s essential to source a lab-grown diamond engagement ring from a reputable vendor. Well-established brands such as GemsNY, Brilliant Earth, and James Allen are known for their high-quality gems, reasonable prices, and stellar customer service. 

Just as you would with a natural diamond, you’ll want to consider characteristics such as shape and cut quality. The shape is a matter of personal preference – some people like the look of a classic round, princess, or emerald, whereas others prefer something more unique, such as a pear, oval, or cushion. If you’re shopping for a diamond engagement ring, you’ll want to choose a beautiful gem of the highest cut quality, so look for either Ideal or Excellent cuts. Other factors to consider include colorlessness (a diamond in the F-H color range should appear colorless) and clarity (a diamond with grade VS1 or VS2 should be free from visible blemishes).

Of course, a ring is more than just a diamond. You’ll also want to consider the type of setting, such as solitaire or halo, and perhaps find out the recipient’s style preferences before making this choice. 

If this sounds overwhelming, you can always reach out to the customer service team at a top jeweler specializing in lab-grown diamonds. They’ll answer your questions and give you an honest assessment of the ring you’re considering. Companies like James Allen, Brilliant Earth, and GemsNY offer returns, so if the jewelry you receive doesn’t meet your expectations, you can always return it for a full refund.

What are the benefits of lab-grown diamond rings? 

Even though they are identical to natural diamonds, lab-grown diamond rings tend to be significantly less expensive – even though they are better for the environment and have a far lower human cost. 

It’s thought that lab-grown diamonds are responsible for significantly fewer gaseous emissions (such as carbon and sulfur oxide) than mined diamonds and can be produced using renewable energy. Unlike mining, synthesizing diamonds doesn’t result in habitat destruction, pollution of water sources, or moving colossal amounts of earth.

Historically, the diamond mining industry has been fraught with human rights abuses such as child labor and prostitution. Even today, many diamond miners in Africa earn less than $1 a day, with the diamond profits going to large corporations rather than to the communities that mine them.  

Frequently Asked Questions About Lab Grown Diamond Rings

Buying a diamond ring is a significant investment, so it’s essential to feel confident and informed. If you aren’t familiar with lab-grown diamonds, there can be even more uncertainty about what’s available. Here are the answers to the most common questions about lab-grown diamond rings. 

What is a lab-grown diamond?

A lab-grown diamond is a diamond created in a laboratory or factory instead of being created underground by the natural forces of temperature and pressure. Lab-grown diamonds are identical to natural diamonds both visually and chemically.

Are lab-grown diamonds real?

Lab-grown diamonds are real. Just like natural diamonds, they are made of pure crystallized carbon. They are indistinguishable from natural diamonds and can be used in the same types of jewelry. The Federal Trade Commission also considers lab-grown gems to be real diamonds.

How are lab-grown diamonds made?

Lab-grown diamonds are made using one of two processes. The High Pressure High Temperature system involves subjecting a diamond “seed” and pure graphite carbon to extremely high temperatures and pressure. The newer Chemical Vapor Deposition process involves heating carbon-rich gas around a diamond seed. 

Where to buy lab-grown diamonds?

Many top jewelry retailers around the world specialize in lab-grown diamonds. Brands such as Brilliant Earth, James Allen, and GemsNY offer high-quality lab-grown diamonds with the exact specifications of mined diamonds, such as clarity, cut grade, and carat weight. 

Do lab-grown diamonds depreciate in value?

Both natural and lab-grown diamond rings depreciate immediately after purchase, losing around half their value the moment you buy them. With a few exceptions, diamond rings are not strong investments. Some jewelers won’t buy back lab-grown diamonds because of their limited resale value.  

Are lab-grown diamonds cheaper?

A lab-grown diamond is significantly cheaper than a natural diamond of the same carat weight, clarity, and cut grade. There’s a lot of variation in the market, but lab-grown diamonds are typically 20% to 50% less expensive than natural diamonds of similar quality. 

Do lab-grown diamonds last as long as real diamonds?

Lab-grown diamonds are just as real as mined diamonds, and they will last just as long. 

Are lab-grown diamonds cubic zirconia?

No, lab-grown diamonds are not cubic zirconia. Although they are created in a lab or factory instead of underground, they are real diamonds with the same chemical composition and appearance as natural diamonds. You can easily distinguish cubic zirconia and other diamond simulants, as they lack brilliance and sparkle.
