What are Lab Grown Diamonds?

Science of Lab Grown Diamonds

The term "lab grown diamond" refers to diamonds that are grown in highly controlled laboratory environments using sophisticated technological processes that mimic the conditions under which diamonds naturally form when they form in the mantle, beneath the Earth's crust. Lab grown diamonds are also known as "man made diamonds," "cultured diamonds," and "lab created diamonds."

The diamonds that were generated in the lab are made of real carbon atoms organized in the typical diamond crystal form. They have the same optical and chemical characteristics as real diamonds because they are composed of the same substance.

Why choose Lab Grown Diamond?

Ethical Sourcing and Sustainable Solutions

Lab-grown diamonds serve as an exceptional alternative to mined diamonds, boasting identical appearance at a lower cost and ethical supply chain. These man-made gems offer several key benefits:

Accessibility to Rare Colors: Lab creation allows for the production of unique diamond colors that are typically rare, making them more readily available to consumers.

Ethical Sourcing: With traceable provenance from reputable vendors, lab-grown diamonds ensure sourcing from sources that prioritize ethical practices and avoid exploitation of individuals or communities.

Sustainable Production: Utilizing processes like HPHT and CVD, lab-grown diamonds meet demand efficiently without compromising quality or resorting to environmentally harmful practices.

How Are Lab-Grown Diamonds Made?

Lab-grown diamonds are made over a matter of weeks using advanced technology perfected to an art. See the processes for two types of lab-grown diamonds below:

CVD (Chemical Vapor Deposition) Diamonds

The process of creating lab-grown diamonds commences with a delicate slice of diamond seed, which is carefully positioned within a sealed chamber and exposed to high temperatures.

Carbon-rich gases are subsequently introduced into the chamber, leading to the fusion of carbon with the diamond seed, resulting in the birth of a new diamond. Following this, the rough diamond undergoes precise cutting to meet stringent standards. Ultimately, the outcome is a diamond boasting identical chemical composition to that of a naturally occurring one.

HPHT (High Pressure, High Temperature) Diamonds

In the initial step, a diamond seed is carefully positioned within a specialized press, where the growth chamber is subjected to temperatures ranging from 1300 to 1600°C, while the pressure applied exceeds 870,000 pounds per square inch.

Molten metal is utilized to dissolve the carbon source, facilitating the growth of a small diamond seed crystal as carbon atoms stimulate its development. Following cultivation, the lab-grown diamond undergoes meticulous cutting to meet stringent standards. Ultimately, the outcome is a diamond boasting identical chemical composition to that of a naturally occurring one.

Comparison Guide


Lab Grown Diamonds

Formation: These diamonds are created in a controlled laboratory environment. They are produced using either High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD) methods.

Cost: Often less expensive than natural diamonds due to the controlled production process and shorter creation time.

Size and Availability: Easier to produce in larger sizes and quantities.

Environmental Impact: Generally considered to have a lower environmental impact, especially if produced using sustainable practices.

Origin: Created by replicating the conditions under which natural diamonds are formed, but the process is accelerated and takes a shorter time.

Natural Diamonds

Formation: Formed deep within the Earth's mantle under extreme pressure and high temperatures over millions or even billions of years, natural diamonds are brought to the surface through volcanic eruptions or other geological processes.

Cost: Typically more expensive, as their formation is a natural and time-consuming process.

Size and Availability: Larger, high-quality diamonds are rarer and, therefore, more valuable.

Environmental Impact: Mining natural diamonds can have significant environmental consequences, including habitat disruption and carbon emissions.

Origin: Mined from 

Cost of Lab-Grown Diamonds

Lab-grown diamonds present a compelling advantage over mined diamonds in terms of cost-effectiveness. Unlike mined diamonds, lab-grown counterparts offer exceptional value for money as they are not subject to the considerable markup often imposed on mined diamonds.

Throughout history, deceptive advertising has perpetuated the notion that a larger diamond signifies stronger love. The diamond industry has a track record of exploiting consumers, with today's culture still adhering to this belief. Consequently, mined diamonds continue to be marked up by at least 100% or more. Fortunately, lab-grown diamonds do not carry such exorbitant markups. When purchasing a lab-grown diamond, you are solely paying for the lab creation process, making them a more affordable option without compromising on quality.

Lab Grown Diamonds

Why are lab grown diamonds are more affordable then natural diamonds?

Lab grown diamonds are more affordable than natural diamonds primarily because of their production process. While natural diamonds have taken millions of years to form under extreme pressure and temperature deep within the Earth's crust, lab grown diamonds are created in a controlled environment using advanced technology that mimics the natural diamond-growing process. This significantly reduces the time and resources required for their formation, resulting in lower production costs and, subsequently, a more affordable price for consumers.

How much do lab grown diamonds cost?

The cost of lab grown diamonds can vary depending on factors such as size and quality. Generally, lab grown diamonds are priced less than natural diamonds of comparable quality.

How can you tell if a diamond is lab grown?

Distinguishing between lab grown and natural diamonds isn’t possible with the naked eye. However, gemologists can identify lab grown diamonds through various methods. Most lab grown diamonds exhibit certain features or "fingerprints" that differ from natural diamonds. One common technique to identify them is using specialized equipment like spectroscopy to view fluorescence patterns. Additionally, some lab grown diamonds may have tiny inclusions or growth patterns that are not typical in natural diamonds, providing further clues to their origin.

Is a lab grown diamond is a real diamond?

Lab created diamonds are diamonds, just like natural diamonds. The primary difference lies in their origin: lab created diamonds are grown in controlled environments, while natural diamonds form naturally in the Earth's mantle. Chemically and physically, They are chemically, physically, and optically identical to natural diamonds, with the same hardness, brilliance, and fire. 

Will a diamond made in a lab get cloudy?

Lab grown diamonds, or man-made diamonds, do not inherently become cloudy. A cloudy appearance in diamonds, whether natural or lab grown, is usually caused by the presence of certain impurities or structural irregularities. High-quality lab grown diamonds are as clear and brilliant as natural diamonds.
