Lab Grown Diamonds vs Natural Diamonds: A Comparison


Lab grown diamonds have been making waves in the jewelry industry, with many people questioning the differences between these man-made gems and natural diamonds. One of the most common questions asked is whether lab grown diamonds are as hard as natural diamonds. In this article, we'll explore the hardness of lab grown diamonds compared to natural diamonds, and delve into the factors that contribute to their hardness.


Understanding Diamond Hardness


Diamonds are known for their exceptional hardness, making them the hardest natural material on Earth. On the Mohs scale of mineral hardness, diamonds score a perfect 10, which signifies their unparalleled resistance to scratching and abrasion. This exceptional hardness is a result of the strong covalent bonds between the carbon atoms in their crystal lattice structure.


The Hardness of Lab Grown Diamonds


Lab grown diamonds are essentially the same as natural diamonds in terms of their chemical composition, crystal structure, and physical properties. This means that lab grown diamonds also exhibit the same level of hardness as natural diamonds, scoring a perfect 10 on the Mohs scale. The process of growing diamonds in a laboratory environment allows for the creation of gems that are virtually indistinguishable from their natural counterparts in terms of hardness.


Factors Affecting Diamond Hardness


While both lab grown and natural diamonds are inherently hard, there are certain factors that can affect their hardness. One of the key factors is the quality of the diamond's crystal lattice structure. Diamonds with a well-ordered and tightly bonded crystal lattice structure will exhibit greater hardness compared to those with structural imperfections. In the case of lab grown diamonds, the controlled environment of the growth process allows for the creation of high-quality crystals with minimal structural defects, contributing to their exceptional hardness.


Another factor that can impact the hardness of diamonds is the presence of impurities or inclusions within the crystal lattice. These foreign elements can weaken the overall integrity of the diamond and reduce its hardness. In the case of natural diamonds, the presence of impurities is not uncommon, and these imperfections can affect the diamond's hardness to varying degrees. However, lab grown diamonds can be produced with minimal to no impurities, further ensuring their hardness is on par with natural diamonds.


The Process of Hardness Testing


To determine the hardness of a diamond, various methods of testing can be employed. One of the most common techniques used is the Vickers hardness test, which involves applying a specific amount of force to the surface of the diamond using a precisely shaped indenter. The size of the resulting indentation is then measured to calculate the diamond's hardness. Both lab grown and natural diamonds undergo the same testing methods to assess their hardness, and the results consistently demonstrate their identical hardness scores.


Conclusion: Lab Grown Diamonds Are Just as Hard as Natural Diamonds


In conclusion, lab grown diamonds exhibit the same exceptional hardness as natural diamonds, scoring a perfect 10 on the Mohs scale of mineral hardness. The controlled growth process in a laboratory environment allows for the creation of high-quality diamonds with well-ordered crystal lattice structures and minimal impurities, contributing to their hardness. Both lab grown and natural diamonds undergo the same testing methods to confirm their unparalleled resistance to scratching and abrasion. Therefore, when it comes to hardness, there is no discernible difference between lab grown and natural diamonds. Whether you choose a lab grown diamond or a natural diamond, you can be confident in the durability and hardness of your precious gem.
