What are Lab Grown Diamonds?

Lab grown diamonds, also known as lab made or cultured diamonds, are created in a laboratory rather than being mined from the Earth’s crust. While natural diamonds are formed over billions of years under tremendous heat and pressure deep within the Earth, lab grown diamonds are created using advanced technology that replicates and expedites the natural diamond-growing process.

The end product is a precious gemstone with the same enchanting physical, chemical, and optical properties as mined diamonds.

It’s fair to say that lab grown diamonds are the biggest disruptor to the mined diamond industry in the history of it’s existence.

The surge in popularity of lab grown diamonds has caught the diamond industry completely off guard.

They’re the perfect bouquet of ethereal beauty and sustainability. Partner this with very attractive pricing, and the sky seems to be the limit.

Are They Real Diamonds?

Yes.

Being authentic diamonds, they exhibit the same hardness, refractive index, and crystal structure as natural diamonds.

Moreover, just like mined diamonds, man-made diamonds can also be cut and polished to produce stunning lab diamond jewelry, including engagement rings, earrings, and necklaces.

Lab diamonds are not diamond imitation stones like cubic zirconia and moissanites.

Can You Tell the Difference by Looking at Them?

No.

To the naked eye, distinguishing between lab grown and mined diamonds is impossible.

The only giveaway would be that the average lab grown diamond is of higher quality than the average mined diamond you find in diamond engagement rings.

Even experienced gemologists need specialized equipment to identify the microscopic differences.

The similarity in appearance extends to lab grown diamond jewelry as well. Unless explicitly informed, it is highly improbable that anyone would discern whether your diamond jewelry is crafted from lab grown or mined diamonds.

Engagement rings, necklaces, and earrings adorned with lab grown diamonds are just as stunning and captivating as those with mined diamonds.

Lab Grown Vs Mined Diamonds: Similarities

Mined diamonds and lab-made diamonds may have different origins, but when it comes to their physical properties and visual appearance, they’ll one and the same.

They are both made up of carbon atoms arranged in a crystalline structure, giving them unique properties and brilliance. This means that whether a diamond is naturally mined from the earth or created in a laboratory, it is still a diamond in every sense of the word.

Identical Appearance & Durability

The two most important practical factors people consider when buying diamonds is durability and appearance.

Lab grown diamonds are perfectly on par with their mined counterparts.

Durability

Diamonds are renowned for their exceptional hardness and durability.

On the Mohs hardness scale, which measures a mineral’s resistance to scratches, both mined and lab grown diamonds score a perfect 10. This makes them the hardest known material, capable of scratching any other mineral.

Regardless of their origin, diamonds’ remarkable durability means they can stand up to daily wear and maintain their polish and brilliance for generations. Therefore, whether you choose an engagement ring made with a lab diamond or a mined one, you can trust that it will last a lifetime… and beyond.

Appearance

In terms of appearance, lab grown diamonds and mined diamonds are virtually indistinguishable.

Both exhibit the same beautiful play of light, known as fire and brilliance, that has captivated people for centuries. The sparkle and shine of a diamond depend on its cut, color, and clarity, not its origin.

Lab grown diamonds can be cut into all the same beautiful shapes as mined diamonds — from classic round brilliants to elegant princess cuts, romantic heart shapes, and more. Similarly, lab diamonds can be found in a range of colors and clarities, including colorless and flawless options that match the highest-quality mined diamonds.

So, whether you’re looking for a stunning engagement ring, a dazzling pair of earrings, or a breathtaking pendant, lab grown diamonds are an excellent choice.

Their identical appearance and durability ensure that you can enjoy the beauty and brilliance of diamonds with a clear conscience.

Certification

Certification plays a vital role in the diamond industry, ensuring consumers that the diamonds they are purchasing are authentic and of high quality. Whether you are considering a lab grown diamond or a mined diamond, obtaining a certification is essential to validate the value and authenticity of the stone.

Lab grown diamonds are graded according to the same exacting standards as their mined counterparts.

Certification is typically carried out by reputable gemological laboratories using standardized grading systems. These laboratories employ trained experts who evaluate various aspects of the diamond, such as its 4C characteristics – carat weight, color, clarity, and cut. The grading process involves rigorous examination and assessment, ensuring that each diamond’s unique characteristics are accurately measured and documented in a unique grading report.

These standards are applied by reputable gemological organizations like the Gemological Institute of America and International Gemmological Institution (IGI), ensuring that whether your diamond is mined or lab grown, its quality, value, and beauty are assessed and verified with the utmost precision and consistency.

This grading process assures buyers that their lab diamond jewelry is of high quality and allows for straightforward comparison with mined diamonds.

Quality Considerations

The quality of a diamond, whether lab-created or mined, is determined by various factors, including its carat weight, color, clarity, and cut. Each of these factors contributes to the overall beauty and value of the diamond.

To determine the quality of a diamond, it’s crucial to consider all these factors together. A high-quality diamond will have a combination of desirable carat weight, excellent color grade, high clarity, and an expertly cut shape.

However, the importance of each factor may vary depending on personal preferences and budget constraints.

Whether it’s a large diamond with a slightly lower clarity grade or a smaller diamond with exceptional color and cut, the choice ultimately lies with the buyer. By considering the various aspects of a diamond’s quality and working with a trustworthy jeweler, you can make an informed decision and find a diamond that meets your specific requirements and brings you joy for years to come.

Lab Grown Vs Mined Diamonds: Significant and Notable Differences

While both lab grown and mined diamonds share similar chemical properties and physical properties, there are some significant and notable differences between the two.

Origin & Creation of Diamonds

The most striking difference between mined and lab-created diamonds is their creation process.

Mined diamonds are formed deep within the Earth’s mantle over millions of years. Through immense pressure and heat, carbon atoms align to create the crystal lattice structure that gives diamonds their exceptional hardness and brilliance. Mined diamonds are then brought to the surface through volcanic eruptions, where they are discovered and extracted through mining processes.

In contrast, man-made diamonds are produced in labs within weeks, replicating the natural diamond formation conditions. One popular technique is Chemical Vapor Deposition (CVD), where a small diamond seed is placed in a chamber with a carbon-rich gas. Through a series of chemical reactions, carbon atoms adhere to the seed, gradually growing into a larger diamond.

This distinction in origin means that laboratory grown diamonds have a shorter and more transparent supply chain compared to the complex and often opaque supply chains associated with mined diamonds.

Price / Cost of Diamonds

When comparing the price or cost of lab grown diamonds versus mined diamonds, there is a significant cost difference.

Lab grown diamonds typically cost 80% less than comparable mined diamonds.

When couples opt for a lab grown diamond engagement ring it usually isn’t a cost-saving excersize. The lower prices of lab grown diamonds make the highest-end specifications and larger diamond sizes accessible.

A mi ned 1,00ct diamond of average quality (J-color VS2-clarity) costs the same as a premium 2,50ct (D-color VS1-clarity) lab grown diamond.

That’s a major difference.

The price difference between mined and man-made diamonds is mainly due to the laboratory process, while sophisticated, avoiding the extensive mining operations and associated costs of mining natural diamonds.

Additionally, the controlled production process of lab grown diamonds allows for a higher yield, meaning more diamonds can be produced simultaneously. This higher production efficiency helps to reduce costs and increase the availability of lab grown diamonds in the market.

The price of both lab grown and mined diamonds varies depending on various factors such as carat size, cut, color, and clarity. Just like with mined diamonds, the value of lab grown diamonds can increase as these factors improve.

Investment Value of Lab Grown Diamonds

The reduced resale value of lab diamonds has been a hot topic recently.

Please remember that though mostly factual, traditional mining companies and industry bodies have pushed much of this information.

Lab diamonds do pose a threat, although not existential, to mined diamonds. And with mined diamonds being marketed as an investment for nearly a hundred years, shooting at the investment value of lab diamonds is a low-hanging fruit.

It’s a myth that if you buy a $10 000 mined diamond it has a resale value of $10 000. Regardless of the over-confident valuation certificate, the jeweller provides you with.

The jeweler took a healthy profit on the deal, and you’ll be lucky if he buys back the diamond from you for $7 000 one year on. True story.

You could have bought the exact same specification lab diamond for $2 000 or less, and even if lab prices go to zero (they won’t) you’ll be better off by $1 000.

And still have the diamond.

Regardless of their resale value, lab diamonds make sense.

Yes, the resale value of lab grown diamonds is lower than that of mined diamonds – but they also cost a fraction of the price of comparable mined diamonds.

Miined diamond prices have also been in decline and now trade at an 18% discount to their previous highs in February of 2022.

Sustainability and Environmental Impact

From an ecological perspective, lab-created diamonds have a significantly lower environmental and social impact than mined diamonds.

The traditional mining of diamonds significantly negatively impacts both the environment and vulnerable communities.

Environmentally, diamond mining can lead to soil degradation and deforestation, as large areas of land are often cleared for mining operations.

This displacement of soil can destroy ecosystems, loss of biodiversity, and disruption of land surfaces, leading to soil erosion and alteration of river paths.

The mining process isn’t clean. It involves gas-guzzling heavy machinery and toxic chemicals, which leads to air and water pollution, negatively affecting the health of local communities and wildlife.

Mining can also often lead to the displacement of local communities, unsafe working conditions, and a lack of economic development despite the high value of the resources being extracted.

Sad but true.

Summary

In conclusion, while lab grown and mined diamonds have their own set of advantages, they share more similarities than differences.

For some, the traditional allure and perceived rarity of naturally-mined diamonds hold significance.

On the other hand, others may find the access to higher quality diamonds, sustainability and ethical qualities of lab grown diamonds more appealing.

The choice between man-made and mined diamonds comes down to personal preference, values, and budget. Whichever you choose, your diamond will symbolize timeless love and commitment.
