What is moissanite fire: How It Compares to Other Gems

Table of Contents

Have you ever heard of moissanite fire? If not, you’re in for a treat. Moissanite fire refers to the unique way that this gemstone, the emerald, sparkles more than a diamond. Its scintillation and shine make it an ideal choice for an engagement ring. Yes, you read that right – more than a diamond! When it comes to engagement rings, emerald gems are a stunning choice. The vibrant green hue and sparkling brilliance of an emerald engagement ring are sure to captivate anyone’s attention. But what exactly is moissanite fire and how does it work to create scintillation and sparkle in this brilliant cut gem?

Moissanite, a naturally occurring mineral, was first discovered by French chemist Henri Moissan in 1893. Known for its colorful fire and sparkle, this mineral reflects light at various wavelengths and cuts. It wasn’t until years later that scientists figured out how to create moissanite rings in a lab setting, making them much more accessible for jewelry purposes. The moissanite rings sparkle beautifully due to their unique cuts and the way they reflect and refract light at different wavelengths.

One of the most fascinating things about moissanite is its ability to refract light in such a way that it creates an incredible amount of sparkle, or “fire.” This is due to the crystal structure of moissanite, which causes light to bounce around inside the stone before being reflected back out, resulting in stunning flashes and cuts.

But how do we measure this fire? That’s where spectrometers come into play. These devices are used to quantify the amount of spectral light dispersion within a moissanite ring, which directly correlates with its level of sparkle and flashes. The cuts of the gemstone enhance its sparkle and flashes.

So why choose moissanite over other gemstones like diamonds? For one, moissanite offers similar levels of sparkle and durability while being much more affordable. Its cuts ensure brilliance and longevity. Because lab-created diamonds sparkle just as beautifully as natural diamonds, they are a more environmentally friendly option compared to mined diamonds. Lab-created diamonds are created in a lab, which cuts down on the environmental impact caused by mining.

What Gives a Gemstone its Fire?

One of the most sought-after qualities of diamonds is their ability to sparkle and disperse light into its spectral colors, also known as fire. The brilliance and cuts of diamonds create a stunning display of color and light. This unique feature adds sparkle and cuts to the stone, making it more valuable and desirable. But what exactly gives a gemstone its fire? Let’s explore.

Refractive Index and Dispersion

The amount of sparkle and fire in a gemstone depends on two main factors: refractive index and dispersion. These factors determine the brilliance and cuts of the gemstone. Refractive index refers to how much the speed of light changes when it passes through a material, creating a beautiful sparkle. The higher the refractive index, the more bending of light occurs, resulting in greater brilliance and sparkle.

Dispersion, on the other hand, refers to how much white light is broken up into its spectral colors when passing through a material, creating a beautiful sparkle. The greater the dispersion, the more colorful flashes or “fire” will be visible within the gemstone, adding a beautiful sparkle.

Ruby’s Exceptional Fire

One example of a gemstone with exceptional sparkle and fire is the ruby. Ruby has a high refractive index of 1.76-1.78 which causes light to bend significantly as it enters and exits the stone creating an intense internal reflection that results in bright flashes of red color.

Ruby has been valued for thousands of years because of this unique characteristic – ancient cultures believed that ruby could bring good fortune and protect against harm.

Moissanite’s High Dispersion

While ruby is known for its high refractive index, moissanite takes center stage.” With a dispersion rating almost twice that of diamond (0.104 compared to diamond’s 0.044), moissanite creates an incredible display of rainbow-colored sparkles that are unmatched by any other gemstone.

Moissanite was first discovered in 1893 by French scientist Henri Moissan while examining rock samples from Arizona’s Canyon Diablo crater. It was later found that the mineral was actually silicon carbide, a compound that is rarely found in nature. Today, moissanite is produced in laboratories and has become increasingly popular as an alternative to diamonds due to its exceptional fire and affordability.

What is Moissanite and How Does it Compare to Diamonds?

Moissanite is a gemstone that was first discovered in 1893 by French scientist Henri Moissan. He found it in a meteorite crater located in Arizona, USA. It wasn’t until the late 1990s that moissanite became available as a gemstone for jewelry.

How Does Moissanite Compare to Diamonds?

When comparing moissanite to diamonds, there are several factors to consider:


As mentioned earlier, moissanites have a higher refractive index than diamonds, making them more brilliant. This means they reflect more light and sparkle more brightly than diamonds.

The science behind facet placement and angle in the brilliant round channelize sunlight through the band more efficiently than other styles.


Diamonds come in different colors ranging from colorless (the most valuable) to yellow or brown (less valuable). In contrast, moissanites are typically near-colorless or have a slight yellowish tint.


The clarity of both stones refers to the presence of imperfections or blemishes within the stone. While diamonds can have visible flaws known as “inclusions,” moissanites are generally free from these types of imperfections.


Perhaps one of the most significant differences between these two stones is their cost. Although prices vary depending on the size and quality of the stone, moissanites are generally less expensive than diamonds. This makes them a popular alternative for engagement rings and other jewelry.

Understanding Gemstone Fire

Defining Gemstone Fire

Gemstone fire is a captivating optical effect, where light entering a gem is dispersed into a rainbow spectrum, similar to light through a prism. This phenomenon is what gives gemstones their vibrant, lively appearance.

Factors Influencing Gemstone Fire

The intensity of a gemstone’s fire depends on its refractive index, cut quality, and clarity. A higher refractive index heightens the potential for fire. Additionally, a well-executed cut maximizes light dispersion, enhancing the stone’s fire.

Moissanite: A Beacon of Fire

Moissanite stands out for its exceptional fire sparkle, surpassing even diamonds in this aspect. With a refractive index of 2.65, moissanite disperses light more effectively, ensuring vibrant colors even under various lighting conditions.

The Importance of Cut Quality

Cut quality is crucial in augmenting moissanite’s fire. A finely cut stone reflects light with optimal dispersion, while a poorly cut one may appear dull. When selecting moissanite jewelry, it’s advisable to opt for stones with high cut grades to fully appreciate their brilliance.

Moissanite vs. Diamond: A Battle of Brilliance and Fire

The Superior Fire of Moissanite

Moissanite, with its higher refractive index (2.65-2.69), surpasses diamonds (refractive index of 2.42) in fire dispersion. This higher refractive index allows moissanite to bend and disperse light more effectively and fiery sparkle, creating more vivid spectral colors and rainbow flashes – the hallmark of a gemstone’s fire.

Why Moissanite Shines Brighter

The science behind moissanite’s superior fire lies in its ability to split white light into a spectrum of colors. This dispersion of light at various angles results in a more pronounced and colorful display of brilliance compared to diamonds. While diamonds do exhibit fire, moissanite’s unique properties enable it to showcase a more intense and varied color play.

For those seeking a gemstone that offers exceptional brilliance and fiery sparkle, moissanite emerges as a clear choice over diamonds. It not only provides a distinctive visual appeal but also comes with the added benefit of being more affordable.

The Advantages of Moissanite Fire
