How Is Moissanite Made?

Have you ever wondered how is moissanite made?

Moissanite is a popular diamond alternative that has gained popularity in recent years due to its affordability and durability.

Moissanite is a naturally occurring mineral made up of silicon carbide, but it is also made in a laboratory setting.

The process of making moissanite involves heat and pressure, just like in nature.

Silicon carbide powder is heated enough to become a gas, and then a carefully-monitored process follows, which ensures that the right chemical and environmental conditions are created, which allow the moissanites to grow over a few months.

The end result is a beautiful and durable gemstone that is virtually indistinguishable from a diamond to the naked eye.

In this article, we will take a closer look at the process of making moissanite, including the materials and methods used in the lab.

We will also explore the pros and cons of moissanite as a diamond alternative, and how it compares to other popular gemstones.

Whether you are in the market for an engagement ring or simply curious about the science behind moissanite, this article will provide you with a comprehensive overview of this fascinating gemstone.

Discovery Of Moissanite

You may be surprised to know that moissanite was discovered over 120 years ago by a Nobel Prize-winning French chemist named Dr. Henri Moissan.

He was researching crystalline chemical compositions ideal for efficient electrical conductivity when he discovered something remarkable and extremely rare.

In 1893, while examining rock samples from a meteor crater located in Canyon Diablo, Arizona, Dr. Moissan discovered a mineral that he initially believed to be diamonds.

However, upon further examination, he identified the crystals as silicon carbide.

This new mineral was named after Dr. Moissan and became known as moissanite.

Natural moissanite is very rare, typically found in kimberlites, lamproites, and meteorites, and only in extremely small quantities.

The discovery of moissanite was significant because it is one of the hardest minerals known to man, second only to diamonds.

However, unlike diamonds, moissanite is a more affordable option for those looking for a beautiful and durable gemstone.

Today, moissanite is manufactured in a carefully monitored process that involves heating silicon carbide powder until it becomes a gas.

The right chemical and environmental conditions are then created to allow the moissanite to grow over a few months.

The result is a beautiful and high-quality gemstone that is becoming increasingly popular as an alternative to diamonds.

Physical And Optical Properties

Moissanite is a lab-created gemstone that is similar in appearance to a diamond.

It has a hardness of 9.25 on the Mohs scale, making it one of the hardest minerals on earth.

This means that it is more durable than many other gemstones, including sapphires and rubies.

Its physical properties make it an ideal choice for engagement rings and other jewelry that is worn every day.

In terms of optical properties, moissanite is the world’s most brilliant gemstone.

It has a refractive index of 2.65 to 2.69, which means that the speed of light refracting in moissanite is 2.65 to 2.69 times slower than the speed of light in the air.

This high refractive index is what gives moissanite its exceptional brilliance and fire, which refers to the way it reflects light.

Moissanite is also known for its sparkle and clarity.

Unlike diamonds, which can have inclusions and blemishes, moissanite is created in a controlled environment, which reduces the likelihood of imperfections.

This means that moissanite is typically eye-clean, which means that it doesn’t have any visible inclusions or blemishes when viewed with the naked eye.

In terms of color, moissanite is typically near-colorless, but it can also have a slight yellow or green tint.

However, this is usually only noticeable in larger stones, and most moissanite used in jewelry is near-colorless.

Overall, the physical and optical properties of moissanite make it an excellent alternative to diamonds.

It is durable, brilliant, and eye-clean, making it a popular choice for engagement rings and other jewelry.

How Is Moissanite Made

Moissanite is a synthetic gemstone that is chemically known as silicon carbide (SiC).

It is made in a lab using a controlled process that involves heat, pressure, and specific environmental conditions.

This section will explain how moissanite is made.

The first step in making moissanite is to obtain silicon carbide powder.

This powder is then placed in a container and heated to a high temperature, causing it to vaporize.

silicon carbide powder

The vaporized silicon carbide then settles onto a substrate, where it slowly crystallizes over time.

This process is known as the Lely process.

The growth of moissanite crystals is a slow process that takes several weeks to months.

During this time, the environment is carefully controlled to ensure that the crystals grow in the desired way.

The resulting crystals are then cut and polished to create the final gemstone.

One of the advantages of moissanite is that it can be made in a variety of shapes and sizes.

This is because the growth conditions can be adjusted to produce crystals of different sizes and shapes.

Additionally, moissanite can be made in a variety of colors, including colorless, yellow, green, and pink.

In conclusion, moissanite is made using a controlled process that involves heat, pressure, and specific environmental conditions.

The resulting gemstone is chemically identical to natural moissanite, but it is more affordable and can be made in a variety of shapes and colors.

Comparison With Diamonds

If you’re considering moissanite as a diamond alternative, you may be wondering how it compares to the real thing.

Here are a few key differences to keep in mind:

  • Hardness and Durability

Diamonds are the hardest substance on earth, with a rating of 10 on the Mohs scale of hardness.

Moissanite is a close second, with a rating of 9.25.

This means that both gems are highly durable and can withstand everyday wear and tear.

However, it’s worth noting that moissanite is slightly more brittle than diamonds, which means it may be more prone to chipping or cracking if subjected to a hard impact.

That being said, moissanite is still a very durable gemstone and is a great choice for everyday wear.

  • Inclusions

Diamonds are prized for their clarity, which refers to the absence of inclusions (internal flaws) and blemishes (external flaws).

Moissanite, on the other hand, is a lab-created gemstone and is typically free of inclusions and blemishes.

While some people prefer the flawless look of a diamond, others appreciate the unique characteristics of moissanite.

Inclusions can give a gemstone character and make it more interesting to look at.

  • Price

One of the most significant differences between diamonds and moissanite is the price.

Diamonds are notoriously expensive, and the price can vary widely depending on the size, cut, color, and clarity of the stone.

Moissanite, on the other hand, is much more affordable and can be a great option for those on a budget.

Keep in mind that while moissanite is a diamond simulant, it’s not a fake diamond.

It’s a unique gemstone in its own right and has its own set of properties and characteristics that make it a great choice for many people.

Overall, whether you choose a diamond or moissanite comes down to personal preference.

Both gems are beautiful and durable, and it’s up to you to decide which one is right for you and your budget.
