Your engagement ring is not a simple piece of jewelry. It’s a love promise, which you hope to carry for a lifetime. Still, choosing that special one becomes a stressful experience for many. The market is full of options, and brides sometimes struggle to know where to start. However, one choice is gaining attention - the lab-grown diamond. It shines just like a mined diamond, is just as strong and beautiful, but comes without the environmental or ethical concerns and usually costs less.
So why the hesitation? Old myths and industry stories have left many couples wondering if a lab-grown diamond is “too good to be true.” Let’s discuss the seven most common lab-grown diamond misconceptions. You will know more about the modern origin of diamonds and whether such a gem is a decent choice for your engagement ring.
Myth 1. Lab-Grown Diamonds Are Fake

People keep saying that diamonds grown artificially are not real gems. Some even say that lab-grown diamonds are made of glass or crystal. However, it’s one of lab-grown diamond myths. Today, you can either mine diamonds or grow them in a laboratory. And in both cases, these are 100% real diamonds.
Both are pure carbon and have the same crystal structure. Both have the same brilliant shine. Their characteristics also match - they’re equally hard, durable, and experts graded them by the standards at places like the GIA and IGI. Even a professional jeweler can’t tell you which is which if it’s not in the lab.
So, what’s the difference? It’s their origin. Natural diamonds grow over billions of years under pressure and heat about 100 miles below the Earth’s surface. Today, we can create the same conditions in a controlled laboratory and grow a diamond in only a few weeks using advanced technology like HPHT or CVD.
The US Federal Trade Commission officially confirmed that lab-grown diamonds are real diamonds. When you buy one, you’re getting the same quality gem. The only nuance is that it was created in a less harmful way. So, are lab-grown diamonds real? Absolutely yes!
Myth 2. They Don’t Sparkle Like Natural Diamonds
Why are people ready to pay crazy money for diamonds? They pay for their irresistible sparkle that resembles magical fire. And it’s often said that lab-grown diamonds do not have this shine. This myth probably means diamonds grown in the 1950s – those were industrial grade and not meant for jewelry. Modern technology is different.
Cultivated diamonds do shine. Sometimes, they can shine better than natural diamonds. They have exactly the same structure, refractive index (2.42), and even dispersion. What makes the diamond sparkle? It’s the finishing done by experts. If this finish is low-grade, even a natural diamond will look dull. Every surface must be skillfully cut at the right angle. Only in this case, the stone provides that sparkle we know. If you cut a cultivated diamond expertly, it will ideally reflect the light, exactly like a natural gem.
Moreover, diamonds that form under controlled conditions in a lab have fewer flaws. That means these stones have ideal optical performance. Experts even conducted visual tests, and most people could not tell where a natural diamond was.
Myth 3. Lab-Grown Diamonds Have No Resale Value
Another big worry is that lab-grown diamonds engagement rings have no resale value. Many people claim these diamonds are mass-produced and won’t cost anything over time. So, what’s the truth?
Yes, lab-grown diamonds usually resell for less than mined ones. But it’s the same story about natural diamonds. Most people who sell a mined diamond only get back 25–50% of what they paid. The resale value of lab-grown diamonds is a bit less, around 20–40%. It’s easy to explain why it’s so - technology improves and production costs reduce.
Still, it doesn’t mean they lose their value. Many people are interested in sustainable production, and resale markets are growing. Some jewelers and online platforms now buy back lab-grown stones, and insurers even cover them like natural ones. Plus, most couples aren’t buying an engagement ring as an investment but as a symbol of love.
And here’s something to consider. Lab-grown diamonds typically cost 60–80% less upfront. It means you can choose a bigger or higher-quality stone for the same budget. In the end, their real value isn’t about resale. It’s beauty, ethics, and what that ring represents for you.
Myth 4. They’re Bad for the Environment

There are even claims that lab-grown diamonds aren’t eco-friendly. It’s because their creation requires much electricity. Partially, it’s correct; however, diamond mining is not good for the planet either. Let’s look at the details.
You must dig up around 250 tons of earth to get a single carat of diamond. It’s destroyed habitats, polluted rivers, and huge open pits on the Earth's surface. The process also requires fuel and water, and leaves a serious environmental impact.
Lab-grown diamonds are made by people. The labs are located in small spaces. They don’t use much water or bring any harm to the environmental systems. Many labs even use renewable power sources, which is also a big plus.
Actually, cultivated diamonds produce up to 90% fewer carbon emissions per carat than mined ones.
So if you are concerned about the future of our, the choice is obvious. A lab-grown diamond is a brilliant way to show your love and care.
Myth 5. Only Mined Diamonds Are Romantic or Authentic
Many people still think that only mined diamonds are truly romantic. In reality, it’s only a story that marketers have been telling us for decades. In that advertising approach, lab-grown diamonds are shown as synthetic or less special.
But the actual lab-grown diamond truth is different. No one’s feelings depend on how long a diamond has been in the earth. They depend on what the ring really means to you and your partner. You can make any ring priceless in the future.
Lab-grown diamonds have their own beautiful story. They’re created with science, care, and purpose. They represent the values of the young generation. Many couples today are environmentally conscious and prefer to avoid planet damage.
When you choose a lab-grown diamond, it’s also romance. You are just writing a modern love story. The age of the diamond doesn’t make it authentic. The stone becomes special for different reasons. Love doesn’t need billions of years to be real.
Myth 6. Lab-Grown Diamonds Are Low Quality
It’s often said that cultivated diamonds are cheaper because they’re lower quality. It’s not true. These diamonds go through the same grading process as mined diamonds. Experts use the same standards to assess them. It’s a 4C scale - cut, color, clarity, and weight.
In fact, these diamonds grow under control and come out cleaner and purer. Many of the lab-grown diamonds are type IIa – you can hardly mine such an exceptional clarity. So why do they cost less? The reason is in the supply chain. Natural diamonds pass through miners and then many hands until they reach the store. Each step increases the cost. Lab-grown diamonds go directly from the lab to the jeweler, so no middlemen.
You can often get a bigger and higher-quality diamond from the lab for the same budget. A flawless lab-grown gem can cost the same as a much smaller mined one.
Lab-grown diamonds aren’t low quality. They actually prove how powerful modern technology is.
Myth 7. You Can Tell the Difference

When you are told you will immediately spot a manmade diamond, it’s one of those lab-grown diamond myths. It’s impossible to visually catch that difference. Cultivated and mined diamonds are like copies, and even most specialists can’t differentiate them without special tools.
Their technical features are identical. And they look and feel identical when worn. You will need to test a diamond in a gemological lab to know its origin. Experts use special machines to detect tiny differences in trace elements or growth patterns. Sometimes, a cultivated diamond may have a small laser inscription to show its origin.
In real life, nobody, not even professionals, will ever tell you what type of stone is in your engagement ring.
So, wear your cultivated diamond with confidence. It’s real and beautiful, especially if you chose it with intention.
