The Science Behind Lab Grown Diamonds

diamond, precious, stone

Lab-grown diamonds, also known as lab-created diamonds, are produced in highly controlled laboratory environments through advanced technological processes that replicate the conditions in which diamonds naturally form beneath the Earth’s crust. These sophisticated techniques result in lab diamonds that are chemically indistinguishable from natural diamonds, making a lab created diamond a desirable choice for modern consumers.

Two techniques are used for producing lab-grown diamonds: Chemical Vapor Deposition (CVD) and High Pressure High Temperature (HPHT). These methods enable diamond manufacturing in a laboratory setting. Each method offers its unique advantages, but both produce lab-grown diamonds that are chemically and optically identical to their natural counterparts.

Understanding how these two groundbreaking techniques work and their differences is crucial.

Chemical Vapor Deposition (CVD)

The Chemical Vapor Deposition (CVD) method involves the use of a diamond seed. It is placed in a small vacuum chamber which is filled with a combination of heated hydrogen and carbon-containing gases. As the temperature reaches around 1500 degrees Fahrenheit, the gas molecules break down, and layers of crystallized carbon begin to form around the seed, eventually producing a larger diamond.

The CVD process offers several advantages:

  • Cost-effectiveness

  • Efficient fabrication of lab-grown diamonds with the same chemical and optical properties as natural diamonds

  • Ability to produce diamonds in distinctive colors and shapes that are not available in nature

These advantages make the CVD process an appealing choice for those seeking unique gemstones.

High Pressure High Temperature (HPHT)

The High Pressure High Temperature (HPHT) method replicates the natural conditions in which diamonds form within the Earth’s mantle. In this process, a machine compresses a specific quantity of carbon material under pressures of more than 870,000 lbs. per square inch at extreme temperatures ranging from 1300 – 1600 degrees Celsius.

The HPHT method:

  • is a reliable and cost-effective approach for producing lab diamonds comparable in quality to natural diamonds

  • enables the production of diamonds in a plethora of colors

  • is an excellent option for those seeking a unique and beautiful diamond.

The Quality and Characteristics of Lab Diamonds

Lab-grown diamonds are identical to natural diamonds in terms of both chemistry and optics, demonstrating the same fire, scintillation, and sparkle. They possess the same physical, chemical, and optical characteristics as those of natural and lab diamonds, making them a viable alternative for discerning consumers.

Unlike natural diamonds, which form deep within the Earth, lab-grown diamonds are manufactured in a laboratory. While lab diamonds have the same chemical composition as natural diamonds, lab and synthetic diamonds possess different chemical compositions and are often composed of materials such as cubic zirconia or moissanite.

Specialized testing is required to distinguish lab-created diamonds from real diamonds, confirming their quality and authenticity.

In addition to their ethical and environmental benefits, lab-grown diamonds also offer the possibility of creating rare and stunning colored diamonds. Starting from a rough diamond, through modification of the gas mix in the CVD reactor and post-synthesis treatments, lab-grown diamonds can be produced in rare hues like vivid yellows, blues, and pinks.

Lab-grown diamonds with fancy colors are formed when trace elements are added during the growing phase, similar to the formation of natural diamonds. In both cases, tiny amounts of these particles are necessary. These mesmerizing hues add a touch of uniqueness and elegance to any piece of jewelry, making colored lab-grown diamonds an attractive choice for those seeking something truly extraordinary.

Ethical and Environmental Advantages

Opting for lab-grown diamonds instead of natural ones offers several benefits:

  • Cost savings

  • Positive contributions to ethical and environmental concerns

  • Reduction in the need for diamond mining, which can have detrimental environmental and social effects

  • Smaller carbon footprint than mined diamonds, making them a more sustainable choice for eco-conscious consumers.

Brands like Brilliant Earth and the Truly Brilliant™ Collection prioritize the planet by offering lab-grown diamonds crafted from renewable energy sources and ensuring that their diamond suppliers are audited for safe and healthy working conditions. By choosing lab-grown diamonds, you are making a responsible and sustainable choice that aligns with your values.

Grading and Certification of Lab Grown Diamonds

Lab-grown diamonds are graded and certified to the same criteria as natural diamonds to ensure their quality and authenticity. Trained gemologists closely examine the diamonds and assign grades based on the ‘Four C’s’:

  • Color

  • Clarity

  • Cut

  • Carat weight

The grading process for lab-grown diamonds is analogous to that of natural diamonds, ensuring that the diamonds you choose meet the highest standards.

By adhering to the same grading and certification process as natural diamonds, lab-grown diamonds provide consumers with the confidence and assurance that they are purchasing a high-quality and authentic diamond. This transparency and attention to detail make lab-grown diamonds an attractive option for those seeking the perfect gemstone.

Pricing and Value of Lab Grown Diamonds

Offering excellent value, lab-grown diamonds are about 50% cheaper than mined diamonds of similar quality. This affordability allows consumers to invest in larger stones or more intricate designs without breaking the bank.

In addition to their lower cost, lab-grown diamonds also come with the assurance of quality and transparency in sourcing. With a discernible source and no connection to conflict or unethical practices, lab-grown diamonds provide an improved value proposition for those looking to make an informed and responsible jewelry purchase.

Lab-grown diamonds find use in a multitude of jewelry styles, including:
