Man-Made Diamonds: Which Clarity Is The Best?

Man-made diamonds, also known as lab-grown diamonds, are produced using two methods: High Pressure-High Temperature (HPHT) and Chemical Vapour Deposition (CVD). Despite being created in a factory, these diamonds still have imperfections similar to natural diamonds, known as inclusions. The best clarity for a lab-grown diamond is Flawless (FL), which means no flaws are visible even when viewed with 10x magnification. Lab-grown diamonds can have more clarity and symmetry than natural diamonds and are less expensive, but demand for them has been falling.

Lab-grown diamonds can have more clarity than natural diamonds

Lab-grown diamonds are often thought to be flawless, with many assuming that their highly controlled production conditions result in a completely pure stone. However, this is not always the case. While it is true that lab-grown diamonds may have fewer and less noticeable inclusions than natural diamonds, they can still have imperfections.

The Clarity of Lab-Grown Diamonds

Lab-grown diamonds are produced in highly controlled conditions, which can result in higher clarity grades than natural diamonds. However, they are still graded on the same scale as natural diamonds and can contain inclusions that impact their overall clarity. These inclusions are usually the result of the extreme temperatures and specific growth conditions in the lab. The most common types of inclusions in lab-grown diamonds are needles, clouds, crystals, feathers, and pinpoints.

The Clarity of Natural Diamonds

Natural diamonds are formed over billions of years under extreme conditions of heat and pressure deep within the Earth. This formation process often results in inclusions from natural minerals. These inclusions can impact the clarity of the diamond, and their appearance can vary depending on the specific growth conditions and environment.

Comparing the Clarity of Lab-Grown and Natural Diamonds

Both lab-grown and natural diamonds are graded using the same system, with the highest grade being Flawless, indicating no inclusions or blemishes visible under 10x magnification, and the lowest grade being Included, indicating obvious imperfections under 10x magnification and visible to the naked eye.

While lab-grown diamonds may have fewer and less noticeable inclusions due to their controlled production conditions, it is still possible for them to have imperfections. In addition, the specific growth conditions and techniques used can result in unique types of inclusions for lab-grown diamonds, such as geometric patterns or layered growth traces.

Factors Affecting Diamond Clarity

Several factors determine a diamond's clarity grade, including the size, nature, number, location, and relief of inclusions. The bigger the inclusion, the lower the clarity grade, as larger imperfections are more likely to impact the diamond's beauty. In addition, inclusions located deep within the stone will have a greater impact on the clarity grade than surface blemishes. The number of inclusions also matters, as a diamond with many imperfections will likely have a lower grade than one with just a few.

The location of an inclusion is also important, as imperfections close to the edge of the diamond are less noticeable than those in the center. Finally, the relief of an inclusion refers to how noticeable it is in relation to the rest of the diamond, with darker blemishes typically standing out more than lighter ones.

Tips for Buying Lab-Grown Diamonds

When buying a lab-grown diamond, it is recommended to look for one that is eye-clean, meaning no blemishes or inclusions are visible without magnification. It is also important to consider your budget and not overspend on a higher clarity grade that may not be noticeable to the naked eye. For smaller diamonds below 2.00 carats, a clarity grade of VS2 to VS1 is generally recommended, while for larger diamonds over 2.00 carats, a minimum grade of VS1 is suggested.

Additionally, it is essential to review high-quality images or videos of the specific diamond you are considering to ensure that it is eye-clean and to look for any flaws or inclusions.

Lab-grown diamonds are formed through a high-temperature carbon-growing and compression process

Lab-grown diamonds are created in a laboratory setting using two methods: High-Pressure, High-Temperature (HPHT) and Chemical Vapour Deposition (CVD). Both methods aim to mimic the natural conditions in which diamonds are formed in the Earth's mantle.

The HPHT method involves exposing a small diamond seed to extreme heat and pressure, replicating the conditions in which diamonds are formed underground. The seed is placed in carbon, the element that diamonds are made of, and heated to temperatures exceeding 2000 degrees Fahrenheit. This causes the carbon to melt and form a diamond around the seed. HPHT diamonds are typically produced without the need for further treatment, though they may exhibit a yellowish hue due to exposure to nitrogen during the formation process.

The CVD method, on the other hand, involves placing a diamond seed in a vacuum chamber filled with carbon-rich gas and heating it to nearly 1500 degrees Fahrenheit. The extreme temperatures cause the gas to turn into plasma, releasing carbon pieces that gradually build up and crystallise into a fully formed diamond. CVD diamonds tend to grow faster and are often treated post-growth to enhance their beauty and remove undesirable traits such as brown undertones and spotty inclusions.

While both methods produce high-quality, authentic diamonds that are optically, chemically, and physically identical to natural diamonds, most experts agree that HPHT diamonds are of superior quality. The HPHT process results in diamonds with ideal aesthetics and fewer imperfections.

The creation of lab-grown diamonds through these high-temperature and compression processes ensures that the resulting gemstones closely resemble natural diamonds in terms of their physical, optical, and chemical properties. The formation of diamonds, whether in a laboratory or the Earth's mantle, relies on the application of intense heat and pressure, causing carbon atoms to crystallise and form the highly valued gemstones we know and admire.

The clarity of a diamond is determined by the size, nature, number, location and relief of the diamond's inclusions

The clarity of a diamond is a key indicator of its quality and price. Diamonds are graded on a scale from Flawless to Included, with 11 grades in total. The clarity grade is determined by the size, nature, number, location, and relief of the diamond's inclusions or blemishes.

The size of an inclusion refers to how big it is, with larger inclusions typically leading to a lower clarity grade as they are more likely to impact the diamond's beauty. The nature of an inclusion refers to whether it is internal or external, with internal inclusions being more desirable as they do not affect the surface of the diamond. The number of inclusions is also important, as a diamond with many inclusions will likely have a lower clarity grade than one with fewer imperfections.

The location of an inclusion also affects its clarity grade. Inclusions that are close to the edge of the diamond are less noticeable and therefore less detrimental to the clarity grade. Inclusions in the centre of the diamond are more obvious and can detract from its beauty. Finally, the relief of an inclusion refers to how noticeable it is in relation to the rest of the diamond. Darker blemishes tend to stand out more and have a greater impact on the clarity grade.

While lab-grown diamonds may have fewer imperfections due to their controlled creation conditions, they are still graded on the same scale as natural diamonds. Lab-grown diamonds can also contain inclusions due to the extreme temperatures used in their creation. The most common types of inclusions in lab-grown diamonds are needles, clouds, crystals, feathers, and pinpoints.

The best clarity for a lab-grown diamond is Flawless (FL)

Lab-grown diamonds may be created in a laboratory, but they still have imperfections similar to natural diamonds. These blemishes and imperfections are referred to as inclusions and are graded on a diamond clarity scale. The fewer the imperfections, the better the clarity grade. While clarity can impact a diamond's value, these imperfections are typically invisible to the naked eye.

The clarity of a lab-grown diamond is determined by examining the diamond under a 10x magnification loupe. Experts look at the size, nature, number, location, and relief of any inclusions or blemishes. The bigger the inclusion, the lower the diamond's clarity grade. If it's a small inclusion, it's likely that it won't affect the diamond's beauty as much.

Lab-grown diamonds often have fewer inclusions and blemishes than natural diamonds due to the highly controlled conditions in which they are grown. However, even with the utmost care and precision, imperfections can still appear as there is no way to entirely control the process.

When it comes to buying a lab-grown diamond, it is recommended to get the most beautiful diamond within your budget. It is important to know your limits and not overspend on achieving a higher clarity grade that may not be noticeable to the naked eye.

Lab-grown diamonds are often considered the epitome of flawlessness

Despite their man-made nature, lab-grown diamonds are not completely flawless. They still contain inclusions and blemishes, similar to natural diamonds. These imperfections are graded on a diamond clarity scale, with the fewer imperfections resulting in a better clarity grade. The size, nature, number, location, and relief of the inclusions all play a role in determining the clarity grade. While most imperfections are not visible to the naked eye, they can impact the diamond's sparkle and overall appearance.

The highest clarity grade for a diamond is Flawless (FL), indicating that no flaws are visible even under 10x magnification. Lab-grown diamonds can achieve this flawless grade, showcasing their exceptional quality. The International Gemological Institute (IGI) provides clarity grades for lab-grown diamonds, ensuring that consumers can make informed choices.

Lab-grown diamonds offer excellent value, as they are 20-50% less expensive than mined diamonds. This allows consumers to purchase larger diamonds with fewer flaws and inclusions compared to natural diamonds in the same price range. The ability to create diamonds in a laboratory setting also bypasses the environmental and ethical concerns associated with mining natural diamonds.

In conclusion, lab-grown diamonds are highly sought-after for their flawlessness, identical characteristics to natural diamonds, and exceptional value. While no diamond is entirely without imperfections, lab-grown diamonds come remarkably close to perfection, making them a popular choice for engagement rings and other fine jewelry.
