Moissanite vs. White Sapphire
White sapphires and moissanites are popular alternatives to diamonds for engagement rings and fine jewelry. Moissanite, a lab-grown gemstone made of silicon carbide, is renowned for its brilliance and fire. White sapphire, a variety of corundum, is naturally occurring but can also be lab-grown and is valued for a subtle, diamond-like appearance.
While both are beautiful and durable, they differ significantly in their physical properties, appearance, and cost. This guide offers a comprehensive comparison to help you make an informed decision.
White Sapphire vs. Moissanite Color
Moissanite is usually colorless or near-colorless, though some may exhibit slight warmth or yellow undertones in certain lighting. High-quality moissanites, especially those on the colorless scale, closely resemble the icy white look of diamonds.
White sapphire, while marketed as colorless, often has faint hues or cloudiness due to natural inclusions. These subtle tints, typically blue, gray, or yellow, are more noticeable in natural white sapphires than lab-grown ones. If achieving a truly colorless look is a priority, moissanite is the better choice. However, white sapphire’s natural appeal may resonate with those who appreciate its unique character.
White Sapphire vs. Moissanite Hardness
When comparing moissanite to sapphire for hardness, moissanite is slightly harder. Moissanite ranks at 9.25 on the Mohs scale, while sapphire, including white sapphire, measures 9. While both gemstones are suitable for daily wear, moissanite’s superior hardness makes it slightly more resistant to scratches and abrasions.
White Sapphire vs. Moissanite Sparkle
Moissanite is known for its exceptional brilliance and fire. Its refractive index is higher than that of white sapphire, allowing it to reflect more light. This creates rainbow-like flashes, making moissanite sparkle intensely, even in low lighting.
White sapphire, by contrast, has a much more subdued brilliance. Its lower refractive index results in a softer, more understated sparkle, making it less comparable to a diamond. While moissanite offers fiery light performance, white sapphire appeals to those seeking a more subtle, elegant appearance.
White Sapphire vs. Moissanite Price
The cost difference is notable when comparing the price of moissanite and sapphire. Natural white sapphires tend to be more expensive, depending on their quality. Moissanite, on the other hand, is typically more affordable.
Main Difference Between White Sapphire and Moissanite
The difference between white sapphire and moissanite lies primarily in brilliance, fire, and durability. Moissanite reflects more light, exhibiting rainbow-like flashes that make it more sparkly than white sapphire, and closer to resembling a diamond. In contrast, white sapphire offers a more subdued brilliance. Additionally, moissanite is harder, making it more resistant to damage over time.
Which Is Better: White Sapphire or Moissanite?
Is white sapphire better than moissanite? The answer depends on your priorities. Moissanite is superior in brilliance, hardness, and durability, making it ideal for those seeking a long-lasting, sparkling gemstone with a more diamond-like appearance. White sapphire, however, appeals to those who prefer a softer, more subdued shine. Whether you prioritize sparkle, durability, or affordability, both options offer unique benefits, allowing you to choose the best gemstone for your needs.
