How Is Moissanite Made? The Technology Behind the Brilliance

French scientist Henri Moissan made the initial discovery of moissanite, a gemstone born of the stars, in a meteor crater in 1893. The hardness and shine of this uncommon material, also known as silicon carbide (SiC), captivated gemologists and scientists.

Since naturally occurring moissanite is quite uncommon, synthetic versions of the stone, like the gorgeous bracelets from MoissaniteCo, are a popular and morally acceptable substitute in jewelry. But how can we, on Earth, produce this diamond born of stars?

The Birth of Synthetic Moissanite

The journey to create moissanite in a lab began with the challenge of replicating its unique properties. It is known for its exceptional hardness, ranking just below diamonds on the Mohs scale, and its brilliant fire, which exceeds that of diamonds. This made it an ideal candidate for use in various industrial applications and later as a gemstone.

Industrial and Gemstone Use

Initially, synthetic primary use was industrial, given its hardness and thermal conductivity. It found applications in abrasives, cutting tools, and high-pressure environments. However, its potential as a gemstone, including the stunning Moissanite bracelets, was undeniable. With advancements in technology, lab-created moissanite became available for use in fine jewelry, offering a sustainable and ethical alternative to diamonds.

The Creation Process

Creating moissanite is a feat of scientific ingenuity. The process mimics the natural conditions in which forms, requiring high temperatures and pressure. This section delves into the technicalities of this fascinating process.

The Lely Method

The Lely Method was the first successful process for creating silicon carbide crystals, the basis of moissanite. Discovered in the 1950s, this process involves vaporizing silicon in a high-temperature furnace and allowing it to deposit onto a substrate. This results in the formation of large, high-quality crystals.

Advancements and Refinements

Over the years, the process has seen significant advancements. Scientists have refined the Lely Method, improving the size, quality, and color of the crystals. The result is moissanite that rivals natural diamonds in appearance and surpasses them in brilliance and fire.

Physical and Optical Properties

Physical and Optical Properties

The allure is found in both its exceptional visual and physical qualities as well as in its ethical and ecological production. It is a sought-after gemstone for jewelry, especially bracelets, because of these qualities.

Hardness and Durability

One of the key attributes is its hardness. Measured at 9.25 on the Mohs scale, it’s second only to diamonds. This hardness translates to exceptional durability, making it ideal for daily wear and resistant to scratches and abrasions.

Brilliance and Fire

The fire and sparkle are unmatched. Because of its larger refractive index than a diamond, it scatters light more widely and produces a rainbow-like appearance. The distinctive brilliance, which is frequently more noticeable than that of a diamond, is caused by this optical feature.

Ethical and Sustainable Choice

Ethical and Sustainable Choice

In today’s world, the ethical and sustainable aspects of gemstones are increasingly important. Moissanite offers a responsible choice without compromising on beauty or quality.

Lab-created moissanite does not contribute to the social and environmental issues associated with diamond mining. It’s a conflict-free option, appealing to those seeking ethically sourced jewelry. Additionally, the environmental impact of creating it is significantly lower than that of mining diamonds.

Affordability and Accessibility

Another advantage is its affordability. It offers the look and durability of diamonds at a fraction of the cost. This makes fine jewelry more accessible to a wider audience, allowing more people to own and enjoy beautiful, high-quality gemstones.

Versatile Applications

Beyond its role as a dazzling gemstone, it finds applications in various industries. Due to its exceptional hardness and thermal conductivity, it’s a preferred choice for abrasives and cutting tools. In the manufacturing sector, moissanite plays a crucial role in precision cutting, drilling, and grinding processes. Its durability and resistance to wear make it an invaluable asset in industrial settings.

High-Tech Innovations

Unique properties have also made it a star in high-tech innovations. Its ability to withstand extreme conditions and maintain its brilliance has led to its use in advanced optics and electronics.

It is employed as a substrate for growing gallium nitride (GaN) crystals, which are essential in high-power and high-frequency electronic devices. This application highlights the importance of pushing the boundaries of modern technology.

The Fascinating Crystal Structure

The Fascinating Crystal Structure

The crystal structure is a marvel of nature. It belongs to the hexagonal crystal system, characterized by its six-fold rotational symmetry. This unique arrangement of atoms gives moissanite its distinct optical properties, such as high birefringence and dispersion. It’s this crystal structure that contributes to extraordinary fire and brilliance, making it a standout gemstone.

Silicon and Carbon Bonding

The crystal lattice is composed of silicon and carbon atoms arranged in a repeating pattern. This strong covalent bonding between silicon and carbon atoms contributes to its remarkable hardness. The tight arrangement of atoms makes it resistant to scratches and abrasions, ensuring its durability in various applications. Understanding the crystal structure is key to appreciating its exceptional properties.

Moissanite vs. Diamond: A Sparkling Comparison


In a glittering match, moissanite triumphs over diamonds because of its brightness and fire. Because of its higher refractive index, moissanite has even more brightness and fire than diamonds, which are prized for their distinctive beauty. As a consequence, a gemstone is created that brilliantly displays colors through the capture and reflection of light. Moissanite has the most glitter of any material.

Durability and Affordability

In the battle of durability, moissanite shines brightly. Its hardness is second only to diamonds, making it an excellent choice for everyday wear. Moissanite bracelets, for example, can withstand the rigors of daily life without losing their luster. Additionally, affordability makes it an attractive option for those seeking luxury without the hefty price tag. This comparison showcases the many advantages of traditional diamonds.


Combining the genius of human technology with the brightness of the stars, moissanite is a miracle of science and beauty. From its industrial beginnings to its use in high-end jewelry, moissanite is a morally sound, environmentally friendly, and reasonably priced choice for anyone looking for durability and beauty. The bracelets offered by MoissaniteCo, which add refinement and elegance to any jewelry collection, are a monument to the charm of this extraordinary gemstone.
