See a live preview of your diamond

When you're shopping for a lab grown diamond, it's easy to get started with Blue Nile. If you're looking for just the stone, you can use a sliding tab that allows you to see either lab grown or natural diamonds. If you're looking to get a ring, Blue Nile allows you to start a "create your own ring” process using only lab grown diamonds, so you don't have to worry about the selection getting mixed up. One of the best features of Blue Nile is that you can see the diamond from any angle with a real 360-degree photo of each gem. This way, you can see how the diamond catches the light before you put it in a setting.

Pricing from $250 to $1,857,300 per diamond

When we priced out lab grown diamonds, we looked at two things: the price range for all the lab grown diamonds at each retailer or jeweler and the prices for the most popular size for engagement rings, which is 1-2 carats in the most popular cuts (round and oval). For these shapes, we also limited our search from clarity levels VS1-FL (the top five), colors F-D (the top three), and only cuts that are ideal or astor ideal. Here's what we found at Blue Nile:

  • Overall price range for lab grown diamonds: $250 to $1,857,300
  • Round: $940 to $2,690
  • Oval: $990 to $2,600

Free services and 30-day returns

Your purchase from Blue Nile will come with a lifetime manufacturer warranty. All items will be free of manufacturing defects, and if you believe it is damaged due to a defect, Blue Nile will repair or replace the item.

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 Diamond Store FAQ

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.
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.
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.
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.
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.
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.
100%. They have the same hardness, toughness, and resistance to scratching and chipping.
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.

Continued from above...

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:

  • Price. Lab grown diamonds are less costly than their earth-bound counterparts, but there is still a difference in price depending on where you buy. Make sure the cost is worth the size (carat) of the gemstone you're grabbing.
  • Cuts. Not all diamonds are the same. Depending on your taste, you may want a different shape or cut that suits your style. Check if your chosen retailer offers your preferred cuts, whether you want round, princess, heart, pear, or something else entirely.
  • Grading report. Some sites sell diamond simulants which are listed as lab created diamonds. However, this isn't the same as a lab grown diamond. You'll want to look for a grading report from a reputable lab like the IGI, EGL, or GIA to ensure that you're getting a real lab created diamond and not a knock off.
  • Reputation. Look to see if your chosen retailer has a top-notch reputation. Check out customer reviews on purchases and returns before you buy. You can also look up your retailer on sites like the Better Business Bureau to see how it stacks up against competing retailers.

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!
