When it comes to choosing a gemstone for your jewelry, the options can be overwhelming. White sapphire vs moissanite are two popular choices that often compete with diamonds for their brilliance and durability. In this article, we will explore the characteristics of moissanite vs white sapphire, their similarities, differences, and how to choose the perfect gemstone for your jewelry needs.

What is White Sapphire?

White sapphire is a type of sapphire that is colorless or white in appearance. It belongs to the corundum mineral family, just like its more famous sibling, the blue sapphire. White sapphires are prized for their hardness, ranking 9 on the Mohs scale, making them an excellent choice for everyday wear.

The Allure of Moissanite

Moissanite, also known as silicon carbide, is a gemstone that has gained popularity as an alternative to diamonds due to its brilliance and affordability. Originally discovered in a meteorite crater, moissanite is now lab-created to produce gem-quality stones.

Brilliance and Fire


Both white sapphire vs moissanite possess exceptional brilliance, giving them a sparkle that rivals diamonds. Brilliance refers to the amount of light reflected back from the gemstone's surface. In this aspect, moissanite tends to have a higher brilliance compared to white sapphire, meaning it reflects more light and sparkles intensely.


Fire refers to the dispersion of light into various colors, creating a rainbow effect. Moissanite exhibits greater fire than white sapphire, making it a show-stopping gemstone with its mesmerizing play of colors.

Color Comparison

White Sapphire:

Despite its name, white sapphire may sometimes display subtle tints of other colors, such as gray or blue. Some individuals prefer these hints of color, as they add a touch of uniqueness to the gemstone.


Moissanite, in its pure form, is also colorless. However, it can exhibit a slight yellow or green tint under certain lighting conditions. Manufacturers have introduced various color grades, from D (colorless) to K (faint yellow or green), allowing customers to choose the desired hue.

Durability and Hardness

White Sapphire:

White sapphire's hardness, rated 9 on the Mohs scale, makes it highly resistant to scratches and everyday wear, making it an excellent choice for engagement rings and other frequently worn jewelry.


Moissanite is also quite durable, scoring 9.25 on the Mohs scale, making it almost as hard as white sapphire. It is an ideal gemstone for daily wear, as it can withstand the rigors of daily life.

Price Comparison

White Sapphire:

In general, white sapphires are more affordable than diamonds but slightly more expensive than moissanite. Their lower cost makes them an attractive option for those seeking a high-quality gemstone without breaking the bank.


Moissanite is significantly more affordable than diamonds and often more budget-friendly than white sapphires. This affordability has contributed to its rising popularity in recent years.

Clarity and Flaws

White Sapphire:

White sapphires are often expected to be eye-clean, meaning they have no visible inclusions or flaws to the naked eye. However, some stones may contain small imperfections that are only visible under magnification.


Moissanite is known for its exceptional clarity, and most gem-quality moissanite stones are eye-clean. The lab-created nature of moissanite allows for better control over its clarity, resulting in minimal inclusions.

Ethical and Environmental Considerations

White Sapphire:

Sapphires, including white sapphires, are typically mined, which can have environmental and ethical implications. Ensure that you source your white sapphire from reputable suppliers that follow ethical and sustainable mining practices.


Lab-created moissanite is an ethical and environmentally-friendly choice, as it is produced in controlled settings without the need for mining. Opting for moissanite helps reduce the environmental impact associated with gemstone mining.

Choosing the Right Gemstone for Your Jewelry

Ultimately, the choice between white sapphire vs moissanite depends on your personal preferences. Consider factors such as brilliance, fire, color, and price to determine which gemstone aligns with your tastes and budget.
