Understanding Moissanite v Lab Diamond

When it comes to choosing the perfect gemstone for your jewelry, many people are torn between moissanite and lab diamonds. This guide will dive deep into the comparison of moissanite v lab diamond, providing vital information to help you make an informed decision.

The Power of Hardness: A Close Rival to Diamonds

On the Mohs scale of mineral hardness, diamonds top the chart at a perfect 10. Moissanite, however, is right behind at 9.25. This makes it one of the hardest gemstones in the world—harder than sapphire or ruby! What does this mean for you? A moissanite gemstone is incredibly resistant to scratching, chipping, and everyday wear, making it ideal for jewelry you’ll treasure forever.

Superior Toughness: Built to Last

Toughness refers to a gemstone's ability to resist breaking or fracturing. Moissanite outshines lab-grown diamonds in this area. While diamonds are famously hard, they can be brittle and prone to cleaving along natural planes. Moissanite, on the other hand, has a more durable crystalline structure, making it less likely to chip or fracture—even with an active lifestyle.

Heat Resistance: Moissanite Takes the Heat

Moissanite can withstand extreme heat without damage, making it a top choice for settings that require intricate work, such as resizing or repairs. With a heat tolerance exceeding 2000°F (1093°C), moissanite is much less likely to crack under pressure than lab-grown diamonds. This also makes it ideal for heirloom-quality jewelry designed to last generations.

Brilliance That Stays Strong

Moissanite doesn’t just rival diamonds in strength—it also outshines them in brilliance. Its refractive index (2.65-2.69) is higher than that of diamonds (2.42), giving moissanite its signature fire and sparkle. What’s more, this brilliance doesn’t diminish over time. While some lab diamonds may lose their clarity due to dirt and oils, moissanite remains bright and captivating with minimal care.

Sustainable and Cost-Effective Strength

Choosing moissanite isn’t just about physical durability—it’s also about financial and ethical strength. Moissanite is a lab-created gemstone, ensuring an environmentally friendly and conflict-free origin. Plus, its affordability means you can invest in a larger, more dazzling gemstone without compromising your budget.
