2026 Lab Grown Diamond Store Reviews

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.

On the Grown Brilliance website

Grown Brilliance is a site that offers only the most sustainable and ethical methods for diamond buying. Instead of offering a range of natural and lab grown diamonds, Grown Brilliance focuses 100% on conflict-free lab grown diamonds. On top of that, all of the jewelry made at Grown Brilliance is crafted from 96% recycled gold to reduce the mining of gold for better sustainability. The company was founded by Akshie Jhaveri, who is a third-generation jeweler, and she has maintained a 75% female-led company through Grown Brilliance's years in business.

Quiz helps you pick your diamond

The browsing experience at Grown Brilliance is a little odd. For example, when you look through the available diamonds, they are displayed in drawing images rather than clear images of each gem. If you want to see a 360-degree interactive image of each lab grown diamond (or even a photo of one), you'll need to click on the individual listing to find what you need. As a bonus, if you're new to diamond-buying or unsure what kind of stone will look best on your finger, you can take a quiz to help you find the best fit for your purposes.

Pricing from $630 to $69,025 per diamond

To do a full price comparison at each retailer, we looked at two things: the price range for all the lab grown diamonds in stock and the cost for round and oval diamonds, which are the most popular shapes for engagement rings. We also limited our search to 1-2 carats, clarity levels VS1-IF, colors F-D, and only ideal cuts (as there were no astor ideal diamonds offered at Grown Brilliance). Here's what we found:

  • Overall price range for lab grown diamonds: $630 to $69,025
  • Round: $665 to $69,025
  • Oval: $665 to $48,335

30-day return policy

At Grown Brilliance, there are plenty of helpful policies to make you feel secure in your purchase. First, Grown Brilliance offers a 30-day return policy. This includes a free return shipping label through FedEx. You can make a return for any reason within that 30-day period. You also get access to a lifetime manufacturing warranty. The warranty applies to all products and includes anything to do with a manufacturing error. However, some things are not included like general wear and tear on your jewelry, trauma, loss of center stones, product loss, or problems caused by improper cleaning or storage.

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.
