When you're shopping for a diamond, it's easy to get overwhelmed with all the options. One of the biggest decisions you might face is choosing between lab grown diamonds vs natural diamonds. If you've heard the buzz about lab-grown diamonds but aren't sure what they really are or how they compare to natural diamonds, you're not alone.
In this post, we'll break down everything you need to know—from how lab-grown diamonds are made and if they're "real," to what makes them different from traditional, mined diamonds. Whether you're buying an engagement ring or just curious, you'll leave with a clearer picture of which option is right for you.
A lab-grown diamond is a diamond created in a laboratory setting rather than forming naturally over millions of years beneath the Earth's surface. These diamonds are produced using advanced technological processes that replicate the high-pressure, high-temperature conditions under which natural diamonds develop.
As a result, lab-grown diamonds possess the same chemical composition, physical properties, and optical characteristics as natural diamonds, making them virtually indistinguishable to the naked eye.
Yes, absolutely—lab-grown diamonds are 100% real! If you're wondering whether they're just fancy knockoffs or something entirely different, let's clear that up.
Lab-grown diamonds have the exact same chemical composition, physical structure, and sparkle as natural diamonds. They're made of pure carbon atoms arranged in a crystal structure, which is what gives a diamond its brilliance and strength.
Just like natural diamonds, lab-grown diamonds are tested and graded on the famous "4Cs" standards—cut, color, clarity, and carat weight. They can also come with diamond certifications from the Gemological Institute of America (GIA) or the International Gemological Institute (IGI), so you can be sure you're getting exactly what you're paying for.
Even gemologists need specialized tools to tell the difference between lab grown vs natural diamonds. So, when you hold a lab-grown diamond in your hand, you're not holding a "fake" or "synthetic" gem—it's as real as any natural diamond.
Lab-grown diamonds are made using advanced technology a controlled laboratory setting that recreates the natural processes responsible for forming diamonds deep beneath the Earth. There are two primary methods: High-Pressure High-Temperature (HPHT) and Chemical Vapor Deposition (CVD).
In the HPHT method, a small diamond seed is placed in a chamber with pure carbon. The chamber is subjected to extreme pressure—about 1.5 million pounds per square inch—and temperatures exceeding 1,500°C. Under these conditions, the carbon melts and crystallizes onto the seed, forming a new diamond. This process can take several days to weeks to produce a gem-quality diamond.
The CVD process involves placing a diamond seed in a chamber filled with a carbon-rich gas mixture, typically methane and hydrogen. The gases are heated to form a plasma, which breaks down the gas molecules, causing carbon atoms to deposit onto the seed.
Over time, these carbon atoms build up layer by layer, forming a diamond crystal. This method allows for precise control over the diamond's characteristics and can produce high-quality diamonds in a matter of weeks.
When comparing lab grown vs natural diamond, the key difference lies in how they're made and their marketed value. Let's take a closer look:
Natural diamonds are formed 90-120 miles beneath the Earth's surface, crystallizing over 1-3 billion years under immense heat and pressure. Lab-grown diamonds, as we've learned, are created in laboratories over a few weeks using advanced technologies like HPHT or CVD that mimic natural diamond-forming conditions.
Both lab-grown and natural diamonds are made of pure carbon and share the same crystal structure, making them virtually identical in hardness, brilliance, and durability. However, there are slight differences in their trace elements. Natural diamonds often contain trace amounts of nitrogen, which can give them a slight yellow tint in some cases.
Lab-grown diamonds, depending on the method used to create them, may lack or have very low levels of nitrogen, resulting in a nitrogen-free or nearly nitrogen-free crystal structure. This absence or reduced presence of nitrogen is one of the factors gemologists can use to identify lab-grown diamonds, along with other characteristics unique to their growth process.
Both lab-grown and natural diamonds are evaluated using the same clarity grading system, which assesses the presence of internal inclusions and external blemishes. The Gemological Institute of America (GIA) clarity scale ranges from Flawless (FL) to Included (I), with several grades in between.
Lab-grown diamonds often have metallic inclusions due to the manufacturing process, while natural diamonds typically have mineral inclusions. However, these differences are usually only detectable under magnification and do not affect the diamond's overall appearance to the naked eye.
When you compare lab diamonds vs real diamonds cost, it's clear that lab diamonds are much more affordable. In fact, their prices have dropped significantly in recent years. Back in 2021, lab-grown diamonds were about 30-40% cheaper than natural diamonds, but by 2024, that price difference has widened—lab diamonds can now be 70-90% less expensive!
For instance, if you were to buy a one-carat lab-grown diamond with Excellent cut, H-I color, VS1-VS2 clarity, it could cost anywhere from $440 to $1,020. In comparison, a similar natural diamond could run you anywhere from $2,110 to $6,080.
Natural diamonds are rare because they take billions of years to form deep within the Earth, which makes each stone unique and valuable. This rarity often gives natural diamonds higher market value and potential for appreciation over time.
In contrast, lab-grown diamonds are produced in weeks, making them more widely available. As a result, lab-grown diamonds generally have a lower resale value due to their abundant supply.
If you're thinking about the planet and ethical sourcing, the choice between lab created diamonds vs real mined ones has some clear distinctions. Mining natural diamonds can lead to environmental issues like habitat destruction, soil erosion, and high carbon emissions.
In contrast, lab-created diamonds are grown in controlled environments with a smaller ecological footprint, using less land and water and producing fewer emissions. They're also conflict-free, meaning there's no link to unethical practices or human rights concerns sometimes associated with mined diamonds.
Now that you're familiar with the differences between lab grown vs natural diamonds, you might be wondering if a lab-grown diamond is right for you. Let's go through its pros and cons to help you make a better decision:
So, when it comes to lab grown diamonds vs natural diamonds, the decision is really up to you. If you're looking for something more affordable, ethical, and eco-friendly, lab-grown diamonds might be the way to go. On the other hand, if you're drawn to the timeless appeal and rarity of a natural diamond, that's perfectly understandable too. Both options have their perks, so take your time, weigh the pros and cons, and pick the one that matches your style, values, and budget. Whatever you choose, you'll be wearing a beautiful diamond that holds special meaning to you.
Yes, lab-grown diamonds are just as good as natural diamonds in terms of quality, durability, and appearance. They have the same chemical, physical, and optical properties as mined diamonds, making them virtually identical to the naked eye.
No, lab diamonds are generally a lot less expensive than natural diamonds. They can cost 70-90% less, allowing you to get a similar-sized or higher-quality diamond for a much lower price.
No, lab diamonds and moissanite are distinct gemstones. Moissanite is a diamond simulant with a different chemical composition and higher refractive index, resulting in greater fire. Although it resembles a diamond, it is not the same material. Lab diamonds, however, are true diamonds, sharing the same chemical and physical properties as natural diamonds.
