White Sapphire vs Moissanite: What’s the Difference?

If you're on the hunt for a dazzling gemstone to make your engagement ring or jewelry truly stand out, chances are you've come across both White Sapphire and Moissanite as brilliant diamond alternatives. Each offers its own unique allure, but there are some key differences that can help you find the perfect match for your style and needs.

Brilliance and Sparkle

One of the first things you’ll notice about Moissanite is its dazzling sparkle. Thanks to its unique crystal structure, Moissanite reflects light in a way that creates a fiery display of colors, often referred to as its ‘fire.’ This brilliant light dispersion can make Moissanite dazzle even in low light. White Sapphire, on the other hand, while lovely, offers a more muted shine and lacks the fiery brilliance of Moissanite. If maximum sparkle is what you’re after, Moissanite is tough to beat.

Durability

Durability is crucial, especially for engagement rings or pieces you’ll wear every day. Moissanite scores 9.25 on the Mohs hardness scale, making it second only to diamonds. This means it’s highly resistant to scratches and wear, ensuring your gemstone stays looking stunning over time. White Sapphire, with a hardness of 9, is still durable but slightly more prone to scratching and may require more upkeep over the years.

Color and Clarity

Both gemstones are known for their clear, white appearance, but there are some subtle differences. Moissanite is typically colorless, closely mimicking a diamond, while White Sapphire can sometimes have faint hints of gray or blue. In terms of clarity, Moissanite is generally eye-clean, free from visible inclusions or imperfections. White Sapphire, however, may have more noticeable inclusions that can affect its overall look.

Affordability

Moissanite and White Sapphire are both affordable options compared to diamonds, but Moissanite typically provides greater value. With its superior brilliance, durability, and clarity, Moissanite engagement rings deliver a high-quality alternative without the steep diamond price. White Sapphire tends to be less expensive initially, but its lower sparkle and durability could result in higher maintenance costs over time.
