The Ultimate Guide to Moissanite: Everything You Need to Know

Introduction

Moissanite sales have grown by 67% in the past three years, making it one of the fastest-growing diamond alternatives in the jewelry market. This remarkable gemstone is capturing hearts worldwide, but what exactly is moissanite, and why are so many people choosing it over traditional diamonds?

La Pretti, a leading destination for ethically-sourced moissanite jewelry, has helped thousands of customers discover the brilliance and beauty of this extraordinary stone. Whether you're considering an engagement ring, wedding band, or statement piece,

understanding moissanite's unique properties will help you make an informed decision.
This comprehensive guide covers everything from moissanite's cosmic origins to its practical advantages, giving you the complete foundation you need to appreciate this remarkable gemstone.


What is Moissanite? The Cosmic Connection

Moissanite is a naturally occurring mineral composed of silicon carbide (SiC) that was first discovered in a meteor crater in 1893 by French scientist Henri Moissan. This cosmic origin gives moissanite a truly otherworldly story that sets it apart from earth-mined gemstones.
  • The Discovery Story: Dr. Henri Moissan initially thought he had discovered diamonds in the Canyon Diablo meteor crater in Arizona. However, further analysis revealed these crystals were composed of silicon carbide. Natural moissanite is incredibly rare on Earth, with most specimens found only in meteorites, making laboratory-created moissanite the primary source for jewelry.
  • Modern Moissanite Creation: Today's jewelry-grade moissanite is created through advanced thermal growing processes that replicate the high-pressure, high-temperature conditions found in space. This controlled environment allows scientists to produce moissanite crystals that are actually more perfect than most natural gemstones, with fewer inclusions and superior optical properties.

 

Moissanite vs. Diamond: Key Differences Explained

Understanding how moissanite compares to diamonds helps highlight its unique advantages:
Property Moissanite Diamond Advantage
Hardness (Mohs Scale) 9.25 10 Diamond (slightly)
Refractive Index 2.65-2.69 2.42 Moissanite
Fire (Dispersion) 0.104 0.044 Moissanite
Price per Carat $400-$600 $3,000-$15,000+ Moissanite
Ethical Sourcing Always lab-created Mining concerns Moissanite
The most striking difference is moissanite's superior light performance—it has 2.4 times more fire (rainbow flashes) than diamond, creating exceptional brilliance that many find more captivating.

The Science Behind Moissanite's Brilliance & Durability

  • Superior Light Performance: Moissanite's higher refractive index (2.65-2.69) compared to diamond (2.42) means it bends light more dramatically, creating greater brilliance. La Pretti sources only optimally cut stones to maximize this natural advantage.
  • Durability for Daily Wear: With a hardness rating of 9.25 on the Mohs scale, moissanite is the second-hardest gemstone after diamond, making it extremely resistant to scratching and chipping. This ensures your moissanite jewelry will maintain its beauty through decades of wear.

 

Environmental and Ethical Advantages

  • Conflict-Free Guarantee: 100% of moissanite is created in laboratories, eliminating any possibility of conflict or unethical mining practices. This gives conscious consumers complete peace of mind about their jewelry's origins.
  • Environmental Impact: Laboratory creation requires significantly less environmental disruption than traditional mining, with no habitat destruction or large-scale earth removal. Choosing moissanite means choosing a more sustainable future.

 

Common Moissanite Myths Debunked

  • Myth #1: "Moissanite Gets Cloudy Over Time"
    • Reality: High-quality moissanite maintains its clarity and sparkle indefinitely. Unlike some diamond simulants, moissanite's silicon carbide structure is chemically stable and won't degrade with normal wear.
  • Myth #2: "You Can Spot Moissanite Easily"
    • Reality: Modern colorless moissanite is virtually indistinguishable from diamond to the naked eye, and even many jewelers need specialized equipment to identify it.
  • Myth #3: "Moissanite is Just 'Fake Diamond'"
    • Reality: Moissanite is its own unique gemstone with properties that actually exceed diamond in several key areas. It's not an imitation—it's an alternative with distinct advantages.
