Is Moissanite a Lab Grown Diamond?
No, moissanite is not a lab-grown diamond. While both are lab-created gemstones, their chemical compositions differ. Moissanite is a gemstone composed of silicon carbide, whereas diamonds—whether mined or lab-grown—are composed of carbon atoms arranged in a crystalline structure. Despite its diamond-like appearance, moissanite is a distinct gemstone with unique optical and physical properties.
Is Moissanite Lab Created?
Yes, the majority of moissanite available today is lab-created. Natural moissanite is rare and found primarily in meteorites, making its extraction impractical for use in jewelry.
Differences Between Moissanite and Lab Diamond
While both moissanite and lab diamonds feature dispersion and scintillation and are considered to be good thermal conductors, moissanites and lab grown diamonds are otherwise different. Here are the main contrasts between moissanite and lab diamond:
Hardness
The Mohs scale measures gemstone hardness, with diamonds ranking highest at 10. Lab-grown diamonds share this perfect score, making them the hardest known material. Moissanite, while also durable, scores a 9.25, making it resistant to scratches but slightly softer than diamonds.
Sparkle
Moissanite exhibits more "rainbow fire" than diamonds, which disperses light into a spectrum of colors. While visually striking, this effect can appear less natural compared to a diamond's sparkle, which features white light reflections known as brilliance.
Color
Lab diamonds are available in a range of color grades from D (the most colorless) to Z (the least colorless). Moissanite, on the other hand, may exhibit a warm undertone under certain lighting conditions, particularly in larger stones. Premium moissanite options are crafted to appear colorless, though differences remain when compared to diamonds.
Price
When comparing moissanite vs. lab diamond pricing, moissanite is generally more affordable. This price difference makes moissanite an attractive option for budget-conscious shoppers.
Moissanite vs. Lab Diamond Side-by-Side
While the untrained eye may visually perceive a moissanite as similar to a diamond, it has a higher refractive index—meaning it produces more “rainbow fire” than a diamond when light hits its surface. This is the most notable visual difference when looking at a moissanite and a lab diamond side by side.
How to Tell the Difference Between Moissanite and Lab Diamond
Identifying the difference between moissanite and lab diamonds often requires specialized tools. Gemological equipment can detect differences in double vs single refraction, hardness, and fluorescence.
Which Is Better: Moissanite or Lab Created Diamonds
The answer depends on your priorities. If you value affordability and unique sparkle, moissanite is an excellent choice. However, if you prefer a gemstone with classic brilliance, lab grown diamonds may be a better option for you. Whether you're seeking a moissanite or lab diamond ring, understanding these differences ensures a purchase that aligns with your style and budget.
