Natural vs Lab Diamonds

Natural and lab-grown diamonds are identical to the naked eye. In fact, most experts can't even tell them apart without specialized equipment. Ultimately, the main difference is how they're created. Learn more to understand which diamond type suits your style.

Diamond Reviews

Model wearing gold diamond engagement ring.

My fiancée (now-wife) comments all the time about how much she loves the ring. I'm not sure that would have happened without Brilliant Earth helping me find the highest quality diamond within my budget.

I had a very easy time using the site. There are pictures of nearly every diamond and really cool features, like 360 images of the rings.

The experience was so easy throughout the entire process. My fiance ordered the ring online, picked up in store without any delivery delays, and was greeted by friendly employees. The diamond selection process is simple, straight forward, and 'flawless'.

Our curated collection of loose natural diamonds and loose lab grown diamonds feature a wide array of dazzling stones that compliment a variety of tastes and budgets. Each one of our diamonds is Beyond Conflict Free™, furthering our mission to cultivate a more ethical, transparent, sustainable, and compassionate jewelry industry. Brilliant Earth natural diamonds and lab grown diamonds are both a stunning and an ethical choice: our diamonds are beautiful, inside and out.


To find a diamond as one-of-a-kind as you are, begin by browsing our selection of diamond shapes: from round to oval, cushion, marquise, pear, emerald, radiant, asscher, princess, or heart. Next, ensure the loose diamonds that you are perusing have grades of cut, color, clarity, and carat that align with your standards. Our cutting-edge technology allows you to easily compare, contrast, and select loose diamonds to find the perfect one.

The best way to tell if a diamond is real is to check for any imperfections or inclusions within the diamond. Real diamonds, whether they are formed naturally or in the lab, will likely have some internal flaws. You can also perform the "fog test" by breathing on the diamond, as real diamonds disperse heat quickly and will not fog up for more than a few short seconds. If you have a mounted diamond, you can take it to a jeweler who can examine it with a loupe, microscope, or diamond tester, which uses electrical conductivity to differentiate between real and fake diamonds. Learn more in our guide.
Diamonds are formed from carbon particles that have been subjected to intense pressure deep within the Earth's mantle. Over time, volcanic activity brings diamonds closer to the surface, where they can be mined. Diamonds are made up entirely of carbon atoms that have been arranged in a specific crystal structure, giving them their unique properties. Lab grown diamonds are formed with the same particles and environments, giving them identical composition and look.
To clean your diamond ring, soak it in warm water with a mild detergent (such as dish soap) for 20-30 minutes before gently scrubbing it with a soft-bristled brush. You can also use a commercial jewelry cleaner but be sure to follow the instructions carefully. Avoid using harsh chemicals or rough, abrasive materials, as these can damage the diamond over time. Additionally, take your diamond ring to a jeweler for professional cleaning and inspection every six months. If your ring is from Brilliant Earth, bring it in to one of our showrooms and we’ll clean it for you, free of charge.

A blood diamond, also known as a conflict diamond, is a diamond that has been mined and sold to fund armed conflict against governments. Conflict diamonds are often mined in war zones, where they are used to finance military operations and human rights abuses. Purchasing blood diamonds directly funds these conflicts and is often linked to violence and exploitation in the diamond industry.

Here at Brilliant Earth, our diamonds are never blood diamonds or conflict diamonds. In fact, our diamonds are Beyond Conflict Free™ and go beyond industry standards to fight against the abuses so often found within the diamond trade.

Moissanite is a type of synthetic gemstone that is often used as a diamond alternative or look-a-like. While it is similar in appearance to a diamond, it is actually made of silicon carbide and has different physical properties. Moissanite is often less expensive than diamonds and has a higher refractive index, which means it can be more sparkly and exhibit a more rainbow-like look than a diamond. Learn more in our guide.
The value of a diamond depends on a variety of factors, including its carat weight, cut, color, and clarity. Larger diamonds (or rather, those with greater carat weights) are generally more valuable, as are diamonds with fewer inclusions and a better cut.
The value of a 1 carat diamond can vary widely, depending on its cut, color, clarity, and other factors. However, as a rough estimate, a 1 carat diamond can be worth anywhere from $1,500 to $10,000.
The value of a 2 carat diamond also depends on its quality, but it can be worth significantly more than a 1 carat diamond. Again, factors like cut, color, and clarity will affect the diamond's value, but a 2 carat diamond can be worth $5,000 to $20,000.
The Hope Diamond is a famous and stunning blue diamond that is estimated to be worth around $250 million. It is currently housed at the Smithsonian National Museum of Natural History in Washington, D.C.
Diamonds are found in several different locations around the world, including Africa, Australia, Russia, and Canada. Most diamonds are formed in the Earth's mantle and are brought closer to the surface through volcanic activity. Some diamond deposits are found in alluvial deposits, where they have been carried downstream by rivers and other water sources. Brilliant Earth diamonds are sourced from ethically vetted mines in Canada and Africa, as well as highly controlled laboratory environments.
To clean diamond earrings, you can use a soft-bristled brush and warm water with a mild detergent (such as dish soap). Gently scrub the earrings and rinse them thoroughly, being careful not to damage the prongs or setting. Alternatively, you can use a commercial jewelry cleaner, but be sure to follow the instructions carefully. Take your diamond earrings to a jeweler for professional cleaning and inspection every six months. If your jewelry is from Brilliant Earth, bring it in to one of our showrooms and we’ll clean and inspect it free of charge.
A simulated diamond is a diamond alternative that is made of materials like cubic zirconia, moissanite, or glass. These stones are designed to look like diamonds but are not actually made of the same materials. Simulated diamonds are often less expensive than real diamonds and can be a good option for those on a budget.
Black diamonds are a type of diamond that are opaque and appear black in color. They are formed from the same carbon material as other diamonds but have a different internal structure that causes them to absorb light rather than refract it. To identify a black diamond, look for its distinctive color and check for any inclusions or imperfections within the stone.
A diamond is a precious gemstone formed from carbon that has been subjected to intense heat and pressure deep within the Earth's mantle. It is known for its hardness, brilliance, and durability, and has been prized for centuries for its beauty and value.
The size of a 1 carat diamond can vary depending on its cut and shape, but as a general guideline, it is about 6.5mm in diameter for a round 1 carat diamond. The size of a diamond is measured in carats, with one carat equaling 0.2 grams.
The value of a 3 carat diamond depends on its quality, but it can be worth tens or even hundreds of thousands of dollars. Factors like cut, color, and clarity will affect the diamond's value, as well as the global diamond market.
Diamonds are so expensive because of their rarity and the high demand for their sparkle. They are also difficult to mine and require a significant investment in equipment and labor.
The cost of a diamond can vary widely depending on its size, quality, and several other factors. A small, low-quality diamond can cost just a few hundred dollars, while a large, high-quality diamond can be worth millions of dollars.
Diamonds are cut using specialized tools, knowledge, and techniques to shape the stone and bring out its beauty and brilliance. The cutting process involves several steps, including planning the cut, cleaving the diamond, shaping the stone, and polishing the final product.
While diamond is one of the hardest substances on Earth, there are a few materials that are even harder. These include wurtzite boron nitride, lonsdaleite, and ultrahard fullerite. These materials are not commonly found in nature and are difficult to produce in a laboratory, making diamonds the hardest substance somewhat readily available in the market.
Raw diamonds come in a variety of shapes and colors, but they generally have a rough, unpolished, and somewhat unattractive appearance. They may appear cloudy or opaque due to the presence of inclusions and other imperfections. Raw diamonds are almost always cut and polished to enhance their appearance and value.
VVS diamonds are diamonds that have a very, very slight inclusion. This means that they have minor imperfections that are only visible under a microscope, not to human eye – especially when set in a piece of fine jewelry. VVS diamonds are high quality and are valued for their clarity and brilliance, making them excellent choices for engagement rings.
