Moissanite is a silicon carbide gemstone that was initially discovered by Dr. Henri Moissan in 1893 within a meteor crater. Due to its extreme rarity in nature, most moissanite today is produced in laboratories. One of its standout features is its exceptional ability to reflect light, often surpassing the sparkle of diamonds. With a score of 9.25 on the Mohs hardness scale, moissanite is highly durable and resistant to scratches. This durability, combined with its lower cost compared to diamonds, makes it an attractive option for fine jewelry. In essence, moissanite provides stunning brilliance and lasting strength without the high price tag of traditional diamonds.

The Fascinating Origin of Moissanite

When Dr. Henri Moissan discovered tiny crystals in a meteor crater in Arizona. At first, these crystals were thought to be diamonds. Later, scientists identified them as silicon carbide. Because finding natural moissanite is extremely rare, it is now produced in labs. This lab creation ensures that moissanite is readily available for jewelry. Its connection to a meteor gives it an interesting history, while its durability and brilliance make it a popular alternative to diamonds today.

How is Moissanite Made?

Moissanite is made in laboratories using advanced techniques that replicate the natural formation process. The primary method is the (HPHT) process. During this process, silicon and carbon are combined under extreme heat (about 2,500 to 3,600°F) and high pressure (5 to 10 gigapascals). This environment mimics the conditions under which natural moissanite forms, such as during meteorite impacts or volcanic activity. The result is a durable and brilliant gemstone with the same chemical and physical properties as natural moissanite. Because it’s lab-created, moissanite is also more ethical, sustainable, and readily available than its rare natural counterpart.

Difference Between Natural and Lab-Grown Moissanite

While natural and lab-created moissanite share many of the same properties, they differ in several other key aspects.

  • Rarity

Natural moissanite forms under very specific and rare conditions, making it incredibly scarce. In contrast, lab-grown moissanite is produced using advanced technology, ensuring a consistent and readily available supply.

  • Appearance

Natural moissanite often contains inclusions, though this doesn’t diminish its brilliance or fire. Lab-created moissanite, however, tends to have fewer inclusions and can be crafted in a range of colors, offering more variety.

  • Cost

Due to its scarcity, natural moissanite is significantly more expensive than lab-grown versions, which are more affordable to produce.

  • Environmental Impact

Mining natural moissanite can lead to significant environmental damage. On the other hand, lab-grown moissanite is a more sustainable and eco-friendly option since it doesn’t require mining.

Key Properties That Make Moissanite Unique And Not Fake Diamond

Moissanite is quite durable, scoring 9.25 on the Mohs hardness scale, so it can withstand regular wear. Unlike diamonds, moissanite is always lab-created, ensuring it is conflict-free and eco-friendly. Moreover, it does not lose its sparkle or change color over time. For these reasons, moissanite is considered a good choice for people looking for a durable and affordable gemstone.

Brilliance and Sparkle of Moissanite And Diamond

When it comes to brilliance, moissanite reflects more light than a diamond because it has a higher refractive index. This means moissanite often appears more sparkly. On the other hand, diamonds have a softer sparkle, which some people prefer for its subtle look. While moissanite produces more colorful flashes, diamonds are often chosen for their timeless elegance. Deciding between the two depends on whether you prefer a bright and vibrant look or a more classic style.

How Hard is Moissanite Compared to Diamond?

Diamonds are renowned as the hardest naturally occurring material, achieving a perfect 10 on the Mohs hardness scale. This exceptional hardness makes diamonds incredibly resistant to scratches, ensuring they can endure a lifetime of daily wear and remain pristine.

Moissanite, while slightly lower on the scale at 9.25, still boasts impressive durability and resilience. This hardness level means moissanite can withstand daily wear and tear remarkably well, making it a practical choice for engagement rings and other fine jewelry. Compared to other gemstones, such as cubic zirconia, which scores an 8, moissanite is significantly stronger and maintains its brilliance and clarity over time without clouding or wearing down.

Additionally, moissanite offers superior brilliance and fire compared to many other gemstones, ensuring lasting sparkle. For those seeking a durable, beautiful, and cost-effective option, moissanite stands out as a reliable and ethical alternative to diamonds, offering exceptional value without compromising on quality or longevity.

Composition and Structure of Natural Diamonds

Diamonds are made entirely of carbon atoms arranged in a crystal structure. This structure gives diamonds their hardness, which makes them resistant to scratches and damage. Natural diamonds form under extreme heat and pressure deep within the Earth over a long time. While natural diamonds are mined, lab-grown diamonds are created using advanced technology. Despite their different origins, both types have the same physical and chemical properties. Diamonds’ unique structure allows them to reflect light, making them a popular choice for jewelry.

It has a light warm tone and falls in the G-H-I range with a slightly warm undertone.

Colored Loose Moissanite: 

It is available in bright colors like green, blue, and pink and is popular for those who like unique designs.

Types of Diamonds:

 Natural Diamonds: 

These diamonds are formed due to extreme pressure and temperature inside the earth and are extracted through mining.

 Lab-Grown Diamonds: 

These diamonds are created in a laboratory and look exactly like natural diamonds, but their manufacturing process is artificial.

 Coloured Diamonds: 

These diamonds come in vibrant colors like yellow, pink, blue, green, etc. due to their chemical impurities or structural variations.

 Synthetic Diamonds: 

These are man-made diamonds that are created in a laboratory but look slightly different from naturally occurring diamonds.

Both the gemstones have their own unique charm, but the types of moissanite and diamond show variations in terms of cut and quality.

Is moissanite a fake diamond?

So far we have learned about natural moissanite and lab-made moissanite. Next, in the second part, we discussed the difference between diamond and moissanite. This makes it clear that moissanite is a natural gemstone in itself, but it is found in very small quantities in nature. Apart from this, it looks exactly like a diamond; perhaps that is why it has been given the tag of synthetic diamond. But there are many differences between it and diamond, except for appearance. It is used more as an alternative to diamond because it provides almost the same beauty at a lower cost than diamond.

Answer

A moissanite is not a fake or cheap diamond, but it is a low-cost alternative to diamond.
