Where is the Best Place to Find Lab Grown Diamonds?  Diamonds are a girl's best friend (and honestly, they're great for guys too), but there's one huge snag that keeps people from grabbing those glittery rocks: cost. Most people think of diamonds and think of dollar signs (and lots of ‘em). However, there are more cost-effective options. And, no, we're not talking about fakes or cubic zirconia lookalikes.

Brilliant Earth is a jeweler that got its start in 2004. The founder and CEO, Beth Gerstein, wanted to find a diamond engagement ring that was ethical and struggled to do so. So, she founded Brilliant Earth to offer a more sustainable and ethical way to buy diamonds and other gemstones. Brilliant Earth promises full transparency: the company tracks where all of its precious metals and gemstones come from and can tell you exactly how each piece of jewelry is made. That way, you never have to question the supply chain or carbon footprint of your beautiful lifetime pieces. As a bonus, 99% of the gold and 95% of the silver used in the jewelry at Brilliant Earth is recycled.

Selection of 391,000+ diamonds

Brilliant Earth has a massive selection of lab grown diamonds. You can expect to see 11 shapes including round, oval, emerald, cushion, elongated cushion, pear, radiant, princess, marquise, asscher, and heart.

Helpful previews of all diamonds

Browsing lab grown diamonds on Brilliant Earth is simple. You can either choose to shop for a ring type (engagement ring or wedding ring) or jump straight into loose diamonds themselves. The top filter bar offers an easy-to-find button that limits the listings only to lab grown diamonds, since Brilliant Earth offers natural diamonds as well. Each diamond has a live video that shows you a 360-degree view of your chosen gemstone. You can look at it close up or far away to give you an idea of how it will look in person and at the size it will be in your ring or other setting.

Pricing from $160 to $163,050 across all diamonds

When we compared prices for lab grown diamonds at each retailer, we looked at two things: the price range for all the lab grown diamonds and the individual costs for round and oval diamonds (the most popular shapes for engagement rings). For the round and oval diamond prices, we also limited our search to diamonds that were 1-2 carats, clarity levels VS1-F, colors F-D, and only ideal or astor ideal (the top two cut levels at Brilliant Earth) cuts. Here's what we found:

  • Overall price range for lab grown diamonds: $160 to $163,050
  • Round: $700 to $41,940
  • Oval: $800 to $5,050

Free warranty and diamond replacement

You can feel a sense of security when choosing Brilliant Earth. This retailer offers a free lifetime manufacturing warranty with every order, which protects against any manufacturing defects. Brilliant Earth will also replace any damaged fine jewelry within 60 days of purchase. Outside of those 60 days, Brilliant Earth will replace any jewelry pieces under $1,000 in value. Brilliant Earth also offers a free lifetime diamond upgrade, which includes lab grown diamonds. Any loose diamond purchased can be exchanged for a credit of your diamond's original value that allows you to upgrade to a stone at least 2x greater in value.

Free shipping and 30-day refunds

On top of protection and replacement, Brilliant Earth offers impressive free shipping both ways, whether it's to you or as a return. The shipping includes insurance and registration of all items for their full value. You'll also get free 30-day returns for any purchase (for a refund or an exchange), and up to 60 days to resize your ring free of charge.

Where is the Best Place to Find Lab Grown Diamonds?

Diamonds are a girl's best friend (and honestly, they're great for guys too), but there's one huge snag that keeps people from grabbing those glittery rocks: cost. Most people think of diamonds and think of dollar signs (and lots of ‘em). However, there are more cost-effective options. And, no, we're not talking about fakes or cubic zirconia lookalikes.

We're talking lab grown diamonds. These diamonds are just as real as the diamonds you find in the earth, but they come at a fraction of the cost. So, what exactly is a lab grown diamond? First - lab grown diamonds are real diamonds. According to diamond experts at the Gemological Institute of America, "lab grown" diamonds and "natural" diamonds have the same hardness and level of durability, the same level of clarity, and are both certified as diamonds.

Lab grown (or man made) diamonds have been created in a controlled laboratory environment. Using techniques like High Pressure High Temperature creation, diamonds can be crafted to look exactly like earth-mined diamonds and have the same chemical and physical makeup as their natural counterparts. The only differences between lab grown and earth-mined diamonds are so tiny no one will ever see them except under serious magnification.

For example, natural diamonds have nitrogen due to the process of being created over millions of years under the pressure of the earth. Lab grown diamond creation simulates that process and cuts down production time to a couple of months. Plus, there isn't any dangerous mining involved in lab grown diamonds, making it much safer, far less costly, and in many cases a more ethical or carbon-neutral choice. The price difference between lab grown and natural diamonds is usually around 30-50% less for a lab grown gem of the same cut and quality, making it possible to purchase a much larger certified diamond without breaking the bank.

So, whether you're looking to get a diamond for your engagement ring, hoping to buy something shiny to treat yourself, or looking to create a new family heirloom, finding a reliable place to get quality lab grown diamonds is important.

If you're not sure which lab-grown diamond jeweler or gemstone retailer is going to be your best bet, don't worry. We've put together a few factors to help you choose the best spot:

To help you enhance your sparkle, Top Consumer Reviews has researched and ranked today's most popular retailers and jewelers for lab grown diamonds. This way you can enjoy the discounts and know you're getting a certified diamond for you or for your special someone. Enjoy your new bling!

Lab Grown Diamond Store FAQ

What are lab-created diamonds?
Lab-created diamonds are gemstones that are grown in a laboratory instead of being mined from the earth. They have the same chemical, physical, and optical properties as natural diamonds.
Are lab-created diamonds real diamonds?
Yes! They have the same characteristics as natural diamonds and can only be distinguished from natural diamonds using specialized equipment. Your lucky recipient - or your friends at girls' night - will never know.
Are lab-created diamonds more ethical than natural diamonds?
Lab-created diamonds are usually considered more ethical than natural diamonds because they are not associated with environmental destruction or human rights abuses. However, the environmental impact of producing lab-created diamonds and the working conditions of lab workers may also be factors to consider.
Are lab-created diamonds more affordable than natural diamonds?
Yes, lab-created diamonds are typically less expensive than natural diamonds of the same quality and size. This is because the cost of producing lab-created diamonds is lower than mining natural diamonds.
Do lab-created diamonds have the same resale value as natural diamonds?
Unfortunately, no. These man-made gemstones have lower resale value than natural diamonds because they are not as rare. However, this may change as lab-created diamonds become more popular and widely accepted in the jewelry industry.
How are lab-created diamonds made?
Lab-created diamonds are made using two different methods: High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD). HPHT mimics the natural diamond formation process by subjecting a small diamond seed to high temperature and pressure. CVD uses a gas mixture to deposit carbon atoms onto a diamond seed, which eventually grows into a diamond.
Are lab-created diamonds as durable as natural diamonds?
100%. They have the same hardness, toughness, and resistance to scratching and chipping.
Can lab-created diamonds be used for engagement rings?
Absolutely! They are a popular and ethical alternative to natural diamonds and offer the same beauty and durability. It's a great way to get a stunning ring at a much lower price than you'd spend for jewelry with natural gemstones. And unless you tell her (or him), your intended will never know the difference.
