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.

Pricing from $110 to $1,573,504 per diamond

Our cost comparison for lab grown diamonds was done by looking at all the lab grown diamonds at Ritani to get a full price range. Separately, we found the pricing for diamonds most ideal for buying a wedding ring. This focused our research on round and oval diamonds, and we also limited the options to 1-2 carats, clarity levels VS1-IF, colors F-D, and ideal cut. For the oval diamonds, there were no ideal cut options, so we had to include all cuts for those. Here's what we found:

  • Overall price range for lab grown diamonds: $110 to $1,573,504
  • Round: $506 to $42,560
  • Oval: $533 to $12,723

Free previews and free returns in 30 days

There are some fun perks when you buy with Ritani. For example, Ritani offers free in-store previews when you design a ring online. This means you can do all the work at home without any pressure and preview your ring in person before you buy. Ritani also offers a standard 30-day return policy. You'll be able to return your items for free within 30 days. Ritani provides a prepaid and insured FedEx 2-day shipping return label when you request your return. If you created a custom ring, however, these cannot be returned and are considered final sale.

Concerns about timelines at Ritani

According to our research, Ritani currently holds an "A+" rating and accreditation from the Better Business Bureau. However, on other third-party review sites, the feedback for Ritani is more nuanced. Currently, Trustpilot shows a mid-tier rating average of just 3 stars out of 5 for this jeweler. People have left recent complaints about slow or unreliable shipping dates, and about issues with customer service. Shoppers also had issues when sending in items for repairs or stone replacements, saying that some repairs were not completed when the items were sent back and that the entire process took weeks.

Good if you want a lot of options

If you're looking for a site with a massive diamond inventory and tons of custom designs, you'll probably enjoy shopping at Ritani. The prices are reasonable for lab grown diamonds. Regrettably, if you're in a rush to get your diamond (or ring setting), you may be disappointed. Reviews show that Ritani is a bit slow no matter what service you're getting from them. For this reason (and the lower ratings from customers overall), it earns an average score from us. But it's still worth a look if you want a massive inventory to pick through.

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.
