While both earth-mined and lab-grown diamonds share an identical chemical structure, detecting the differences between them requires advanced equipment and expertise. Only trained gemologists can spot variations in growth patterns or inclusions using specialized technology, like UV fluorescence imaging and specific laser inscriptions. However, to the untrained eye and without this equipment, the two appear indistinguishable.

conductivity, a property lab-grown diamonds share with natural diamonds, resulting in a positive test for both. Advanced diamond testers also identify diamonds versus other gemstones, ensuring authenticity. So, whether mined or lab-grown, both types of diamonds show a positive result on reliable testers, reassuring jewelers and consumers alike about the genuine nature of the diamond in question.

No, lab-grown diamonds are not fake. They are genuine diamonds with the same chemical, physical, and optical properties as natural diamonds. The primary difference is origin: lab-grown diamonds are created in controlled laboratory settings using advanced technology that mimics the high-pressure, high-temperature conditions found underground. This is comparable to ice made in a freezer versus ice from a glacier—they’re both real ice, just formed in different ways.

Lab-grown diamonds have the same hardness, brilliance, and beauty as mined diamonds, making them a legitimate and ethical choice for consumers who value sustainability and transparency.

No, lab-grown diamonds do not all look alike. Just like natural diamonds, lab-grown diamonds vary in color, clarity, cut, and carat weight.

Yes, lab-grown diamonds can retain value, but quality matters. Diamonds without post-treatment and those with a reputable grading certificate hold value better. However, lab-grown diamonds typically don’t appreciate in value like natural diamonds, and their price tends to remain stable.

Lab-grown diamonds are made using two main methods: HPHT (High-Pressure High-Temperature) and CVD (Chemical Vapor Deposition). HPHT simulates natural diamond formation with extreme pressure and heat, while CVD uses a gas mixture to deposit carbon onto a diamond seed. CVD is preferred for producing high-quality diamonds with better consistency and fewer impurities. At Carbonera, we primarily use CVD to ensure top-tier quality.

Chemical Vapor Deposition (CVD) is a process used to grow lab-grown diamonds. It begins with a small carbon seed placed inside a low-pressure microwave chamber. In this chamber, hydrogen and methane gases are combined with electrical energy, which creates a plasma ball. This plasma forms a cloud, and carbon molecules rain down onto the seed, gradually growing into a rough diamond over 6 to 12 weeks. The resulting diamond is then cut, polished, and graded by certified labs, just like natural diamonds. CVD is widely used for creating high-quality diamonds due to its precision and controlled environment.

High Pressure High Temperature (HPHT) is a diamond-growing process that simulates the extreme conditions found deep within the Earth. It is commonly used to produce smaller gem-quality diamonds, ideal for use in jewelry. The process involves a BARS press, a technology developed by Russian scientists, which uses a combination of inner and outer anvils to apply immense hydraulic pressure on the growth cell.

The growth cell contains a diamond seed, highly refined graphite, and a mixture of metals and powders. When exposed to temperatures up to 1,300°C and pressures exceeding 50,000 atmospheres, the elements inside the cell melt and reform, producing rough lab-grown diamonds. These diamonds are then extracted, cut, polished, and graded for their final use in jewelry. HPHT is known for creating diamonds with natural characteristics that are highly sought after for their purity and brilliance.

Carbon-captured diamonds, also referred to as carbon-neutral diamonds, are lab-grown diamonds created using a process that captures and recycles carbon emissions from the atmosphere. This method helps mitigate environmental damage by reducing the greenhouse gases that contribute to global warming. Essentially, these diamonds are produced by utilizing carbon that would otherwise be harmful to the environment, transforming it into something beautiful and valuable.

This innovation makes carbon-captured diamonds an eco-friendly choice for consumers who are concerned about sustainability. By reducing the carbon footprint associated with diamond production, they offer a responsible alternative to traditionally mined diamonds, ensuring that consumers can enjoy luxury without compromising environmental integrity.

The choice between Chemical Vapor Deposition (CVD) and High Pressure High Temperature (HPHT) for creating lab-grown diamonds depends on the desired outcome. CVD is often considered the better method for producing large, high-quality diamonds, particularly when the process is slow and controlled. It is generally more energy-efficient, making it an eco-friendly option compared to HPHT.

On the other hand, HPHT is typically used for smaller diamonds or diamonds where color enhancement is a priority. Although it can create beautiful diamonds, especially for those looking for intense color, CVD is often regarded as the more sustainable and versatile option for high-quality lab-grown diamonds.

Both methods have their merits, but CVD is favored for its ability to produce larger and higher-quality diamonds in an energy-efficient manner, aligning with sustainability goals.

If your lab-grown diamond is treated, it means that certain processes have been applied to alter its appearance. Common treatments include color enhancement to improve the diamond's color or fracture filling to mask imperfections. These treatments can be necessary when diamonds are created quickly or with lower-quality conditions, resulting in imperfections or undesirable colors, like brown.

While treatments can improve a diamond's visual appeal, they might also affect its long-term value, durability, and overall stability. It's important to purchase from reputable sellers who provide transparency regarding any treatments applied. Always request details about treatments to make an informed purchase decision.

For the highest quality, consider untreated lab diamonds that have been carefully grown and polished without post-treatment for optimal value and integrity.

An “As Grown” diamond refers to a lab-grown diamond that has not undergone any post-treatment or enhancement after its creation. This means the diamond retains its natural appearance, with its color, clarity, and other characteristics unchanged from its growth process. These diamonds are often preferred by buyers who seek authenticity and value in a diamond that has not been artificially altered to achieve colorlessness or improve clarity.

Choosing an "As Grown" diamond ensures you are purchasing a stone that is free from any artificial modifications, preserving its original quality and integrity. This also ensures a more transparent and sustainable purchase.

Colored lab-grown diamonds are created by introducing specific trace elements during their growth process. These elements impact the final color of the diamond. For instance, boron causes the diamond to appear blue, while nitrogen creates yellow or orange hues. Additionally, exposure to radiation can generate green or pink diamonds. These diamonds are produced using controlled methods like Chemical Vapor Deposition (CVD) or High Pressure High Temperature (HPHT) to ensure the precise color desired. The process allows for the creation of diamonds in a variety of stunning colors while maintaining the diamond’s inherent brilliance and durability.

Lab-grown diamonds are real diamonds, created in labs with the same physical, chemical, and optical properties as mined diamonds. Made from pure carbon, they possess the same brilliance and durability as natural diamonds. In contrast, diamond simulants like cubic zirconia or moissanite mimic the appearance of diamonds but do not have the same chemical composition. They are less durable, softer, and more prone to scratches than actual diamonds. While simulants are affordable alternatives, lab-grown diamonds are authentic diamonds with long-term value and strength.

A grading report, also known as a diamond certificate, offers a comprehensive assessment of a diamond's characteristics and quality. It provides an independent verification of the diamond’s attributes, such as carat weight, cut, color, and clarity, which help determine its value. Lab-grown diamonds are graded based on the same standards as natural diamonds, ensuring that buyers can trust their quality.

Pro Tip: Some companies grade their own diamonds, which can create a conflict of interest. Always choose a diamond with an independent grading report from a trusted lab, such as IGI, GIA, or GCAL.
