Moissanite vs White Sapphire: A Comprehensive Comparison – When it comes to choosing the perfect gemstone for your jewelry, the options can seem endless.

Moissanite and white sapphire are two popular alternatives to traditional diamonds, offering beauty and brilliance without the high price tag.

In this comprehensive article, we will discuss about Moissanite vs White Sapphire, comparing their characteristics, durability, ethical considerations, and cost.

By the end, you’ll have a clear understanding of the differences between these two stunning gemstones and be better equipped to make an informed choice for your next jewelry purchase.

Composition and Origin

To understand the differences between moissanite vs white sapphire, it’s essential to first examine their composition and origins.


Moissanite is a naturally occurring mineral, but the moissanite used in jewelry is typically lab-created. Natural moissanite is incredibly rare and is found in meteorites.

However, lab-created moissanite, also known as silicon carbide, is the one commonly used in jewelry. It is created through a controlled process that mimics the conditions in which natural moissanite forms. This lab-grown version exhibits exceptional brilliance and fire, making it a popular choice for engagement rings and other fine jewelry.

White Sapphire:

White sapphires, on the other hand, are a variety of the mineral corundum. Corundum is the same mineral that produces rubies and sapphires of other colors, including blue and pink.

White sapphires, as the name suggests, are the colorless or “white” variety of this gemstone. They are entirely natural and are mined from various locations worldwide, including Sri Lanka, India, and Madagascar.

White sapphires are known for their hardness and durability, which we will explore in more detail later.

Brilliance and Fire

When it comes to gemstones, brilliance, and fire are terms often used to describe their ability to reflect and refract light, creating that mesmerizing sparkle.

Let’s compare moissanite and white sapphire in terms of these essential characteristics.


Moissanite is renowned for its extraordinary brilliance and fire. It has even been described as having more brilliance than diamonds. This is due to its exceptional ability to disperse light into a stunning spectrum of colors.

When light enters a moissanite gemstone, it breaks into flashes of rainbow colors, creating a captivating play of light. This property makes moissanite a top choice for those who desire maximum sparkle in their jewelry.

White Sapphire:

White sapphires, while still beautiful, exhibit a slightly different play of light. They are known for their brilliant, icy-white appearance but tend to have less fire and dispersion compared to moissanite. White sapphires rely more on their crystal clarity and transparency to create their allure.

They offer a subtle and elegant sparkle that appeals to those seeking a more understated and sophisticated look in their jewelry.

Hardness and Durability

The hardness and durability of a gemstone are crucial factors to consider, especially for jewelry that will be worn daily. Let’s examine how moissanite vs white sapphire stack up in this regard.


Moissanite is one of the hardest known minerals on Earth, ranking 9.25 on the Mohs scale of hardness. This exceptional hardness makes it highly resistant to scratching and abrasion, making it an excellent choice for engagement rings and other jewelry that will endure daily wear and tear.

Moissanite’s durability ensures that it will maintain its brilliance and sparkle for a lifetime.

White Sapphire:

White sapphires are also relatively hard, scoring 9 on the Mohs scale, just slightly below moissanite. This hardness makes white sapphires quite durable and suitable for everyday wear.

However, it’s essential to note that their lower hardness compared to moissanite means they are slightly more prone to scratching over time.

Nevertheless, with proper care, white sapphires can remain a beautiful and durable choice for jewelry.

Clarity and Inclusions

The clarity of a gemstone refers to the presence of internal flaws, known as inclusions, and external blemishes. Let’s explore how moissanite vs white sapphire differ in terms of clarity.


Lab-created moissanite is typically very clear and free from inclusions and blemishes. This high level of clarity contributes to its exceptional brilliance.

However, it’s essential to note that moissanite can sometimes exhibit a characteristic known as “double refraction,” where the gemstone appears to have double facets when viewed from certain angles.

While this is a natural property of moissanite, it’s not typically visible to the naked eye and does not detract from its overall beauty.

White Sapphire:

White sapphires are also known for their excellent clarity. They are often eye-clean, meaning they do not have visible inclusions or blemishes when viewed without magnification.

The high clarity of white sapphires enhances their brilliance and transparency, allowing them to showcase their natural beauty without distractions.

Color and Transparency

Both moissanite and white sapphire are prized for their colorless or white appearance. However, there are subtle differences in their color and transparency.


Moissanite is usually completely colorless and transparent. It lacks any noticeable tint or hue, which allows it to closely mimic the appearance of a high-quality diamond. This colorlessness is highly desirable for those who prefer a classic and timeless look in their jewelry.

White Sapphire:

White sapphires, as the name suggests, are also prized for their white or colorless appearance. However, some white sapphires may exhibit a faint grayish or blueish undertone. This is often not visible to the naked eye and varies from one stone to another.

It’s essential to choose a high-quality white sapphire to ensure a clear and transparent gemstone for your jewelry.

Cost Comparison

One significant factor that often influences the choice between moissanite and white sapphire is cost. Let’s explore how these two gemstones compare in terms of price.


Moissanite is known for its affordability compared to diamonds. While it is still more expensive than white sapphire, it offers a remarkable balance between cost and brilliance.

The price of moissanite can vary depending on the size and quality of the gemstone, but it is generally more budget-friendly than many other gemstone options. This affordability makes moissanite an attractive choice for those looking to maximize the size and sparkle of their jewelry without breaking the bank.

White Sapphire:

White sapphires are generally more affordable than moissanite but tend to be more expensive than other colorless gemstones like cubic zirconia.

The price of white sapphires can also vary based on factors such as size, quality, and origin. While they are an economical alternative to diamonds, they may not offer the same level of brilliance as moissanite. 

However, for those who prioritize a natural and traditional gemstone, white sapphire can be an appealing choice.

Ethical Considerations

Ethical considerations have become increasingly important to consumers when choosing gemstones. Let’s discuss the ethical aspects of moissanite vs white sapphire.


Lab-created moissanite is considered an ethical choice in the gemstone world. Since it is synthetically grown in controlled environments, there are no concerns related to mining practices, child labor, or environmental damage associated with its production.

Many buyers appreciate the transparency and ethical standards upheld by moissanite manufacturers.

White Sapphire:

The ethical considerations surrounding white sapphire are also positive, but there are some nuances to be aware of. While white sapphires themselves are natural gemstones and do not involve the same ethical concerns as diamonds, the mining industry, in general, can have negative environmental and social impacts.

It’s crucial to ensure that the white sapphires you purchase are sourced responsibly, and many reputable jewelers provide information about their ethical practices.


In the debate of moissanite vs white sapphire, both gemstones offer unique qualities and advantages. 

Moissanite dazzles with its exceptional brilliance and fire, closely resembling the look of a high-quality diamond. It is incredibly durable and scratch-resistant, making it an excellent choice for daily wear. On the other hand, white sapphires boast natural elegance and transparency, offering a subtle yet sophisticated sparkle. They are an ethical and budget-friendly alternative to traditional diamonds.

Ultimately, the choice between moissanite and white sapphire comes down to your personal preferences and priorities. If you seek maximum sparkle and are comfortable with lab-created gemstones, moissanite may be your ideal choice. If you prefer a natural gemstone with a more understated elegance and ethical considerations, white sapphire could be the perfect fit.

When making your decision, consider factors such as your budget, the style of jewelry you desire, and your ethical values. Both moissanite vs white sapphire have their place in the world of gemstones, offering beauty and brilliance that can enhance any piece of jewelry.
