Moissanite (also known as Carborundum) is a gemstone composed of silicon carbide (SiC). Natural moissanite is extremely rare and cannot be found in sizes large enough to cut into gemstones. Therefore, all moissanite used in jewelry today is lab-grown. It comes in a wide range of colors — including blue, emerald green, burgundy, dark grey, champagne, bright yellow, purple, and black — making it highly popular among modern jewelry consumers.
1、Key Characteristics of Moissanite
Moissanite is a classic diamond simulant — visually similar to diamonds but far more affordable. The price difference is mainly due to supply and market demand, rather than quality.
Distinctive features of moissanite include:
Refractive index of 2.65–2.69, producing even stronger brilliance and fire than diamonds
Price range: USD $250–$1,000 per carat
Laboratory-grown, environmentally friendly, and free from conflict-related concerns
High clarity, with fewer inclusions compared to natural diamonds
A slight “double faceting” effect may be visible from the side — a natural feature of its crystal structure
2、Origin of Moissanite: From Meteorites to Lab-Grown Gems
Moissanite was first discovered in a meteorite crater in Arizona, USA, by French scientist Henri Moissan. Because of its diamond-like appearance, he initially believed he had discovered a new diamond deposit, but later confirmed the material to be silicon carbide.
Although the “born from space” story is fascinating, natural moissanite is far too rare for jewelry use. Modern moissanite is therefore entirely lab-grown, offering stable quality and traceable origins.
3、Moissanite vs. Lab-Grown Diamonds
Lab-Grown Diamonds
Same structure and composition as natural diamonds (pure carbon)
Produced using HPHT or CVD methods in 3–5 days
Identical optical and physical properties to mined diamonds
More affordable and environmentally friendly
Moissanite
Composed of silicon carbide
100% lab-grown
Exhibits stronger brilliance and higher refractive index than diamonds
Significantly more cost-effective
Typically higher clarity with fewer natural inclusions
4、Core Advantages of Moissanite
Why is moissanite increasingly favored by consumers and jewelry brands?
Stronger fire and brilliance — more dazzling than diamonds
High durability— Mohs hardness of 9.25, suitable for daily wear
Excellent clarity due to controlled lab-growing conditions
Outstanding value for money— only a fraction of diamond prices
Eco-friendly and conflict-free
These strengths make moissanite a top choice for engagement rings, affordable luxury jewelry, and brand product lines.
5、Conclusion: Is Moissanite Right for You or Your Brand?
Diamonds remain important in high-end jewelry due to their rarity and symbolism. However, moissanite — with its exceptional brilliance, durability, and affordability — stands out as an attractive alternative.
Whether you are curating products for a brand or selecting a gemstone for a client, moissanite offers a beautiful, durable, and budget-friendly option.
