What is Moissanite?
Moissanite is a lab-created gemstone composed of silicon carbide and is commonly referred to as a diamond simulant. Its discovery dates back to 1893 when Nobel Prize-winning chemist Henri Moissan found it in a meteorite crater at Canyon Diablo, Arizona. Initially mistaken for diamonds, it wasn't until 1904 that Moissan correctly identified these crystals as silicon carbide. The mineral was later named in honor of Moissan.
Rarity and Natural Occurrence
Natural moissanite is extremely rare. It wasn't until 1958 that geologists found moissanite outside of meteorites. They first discovered it in the Earth's upper mantle near Wyoming, followed by inclusions in rocks in Russia the next year.
Sustainable Creation in Laboratories
Today, moissanite is predominantly created in laboratories, providing a sustainable and ethical alternative to diamonds. Advanced technology in controlled environments allows for the production of high-quality moissanite, eliminating the need for mining and reducing the environmental impact. This process ensures moissanite is easily traceable and has a significantly smaller carbon footprint.
Growing Popularity in Jewelry
Moissanite has become increasingly popular as a cost-effective and environmentally friendly alternative to diamonds, especially for engagement rings. Its exceptional brilliance and affordability make it a sought-after choice for many.
Moissanite vs. Diamond: Key Differences
Although moissanite and diamonds may look similar, they are fundamentally different. Diamonds consist of carbon, while moissanite is made of silicon carbide. Here are some distinct differences:
- Refractive Index: Moissanite has a higher refractive index (2.64 to 2.69) compared to diamonds (2.417 to 2.419), resulting in greater brilliance and fire.
- Hardness: On the Mohs scale, diamonds score a perfect 10, making them the hardest known mineral. Moissanite is also very durable with a rating of 9.25.
- Thermal Conductivity: Both gemstones are good thermal conductors, but moissanite exhibits more intense fire.
| Moissanite | Diamond | Lab Diamond | |
| Durability | 9.25 on the Mohs scale | 10 on the Mohs scale | 10 on the Mohs scale |
| Brilliance | More brilliant with higher fire | Slightly less brilliant, less fire | Slightly less brilliant, less fire |
| Color | Available in colorless, teal, grey, green, yellow, and black | Colorless to various colors | Colorless to vibrant fancy colors |
| Price | Less expensive than diamonds | Most expensive due to rarity | More affordable than natural diamonds, pricier than moissanite |
| Sourcing | Grown in labs, no mining involved | Naturally mined | Grown in labs, no mining involved |
Identifying Moissanite from Diamonds
To differentiate moissanite from diamonds, place them side by side. Diamonds have a unique sparkle that combines reflected light, color refraction, and scintillation. In contrast, moissanite shows more intense rainbow flashes or 'fire,' especially in larger sizes. This 'disco ball' effect is a quick visual cue.
Professional Verification
For a precise identification, consult a gemologist. They can examine the stone with a loupe to check for the 'doubling' of facet junctions, confirming whether it is moissanite or a diamond.
Conclusion
Moissanite offers a stunning, eco-friendly, and affordable alternative to traditional diamonds. Its unique properties and exceptional brilliance make it a fantastic choice for engagement rings and other fine jewelry. Whether you’re captivated by its celestial origins or its dazzling sparkle, moissanite is a gem that stands out in any collection.
