Moissanite diamonds
When evaluating what is the best quality moissanite, consider its optical characteristics. Look for clear, colorless stones with no visible flaws, and a cut that maximizes brilliance and sparkle. Opt for reputable vendors offering transparent grading reports for an informed choice.

When evaluating the quality of moissanite, a diamond simulant, it is essential to consider its origins and properties. Moissanite is a form of silicon carbide and it is recognized for its hardness, which is second only to diamonds on the Mohs scale, and for its brilliant sparkle. Quality variations in moissanite are often determined by factors such as clarity, color, cut, and carat weight—similar to traditional diamond grading.

I assess the best quality moissanite by paying close attention to its optical characteristics. Ideally, top-tier moissanite should have a clear, colorless appearance without any visible inclusions or blemishes.


The cut should enhance its natural brilliance, maximizing the stone's fire and creating exceptional sparkle. In the market for moissanite, recognizing these attributes ensures a selection that rivals the finest diamonds in appearance while providing a unique charm.

Moissanite also offers a more ethical and affordable alternative to diamonds, without compromising on the desired aesthetic. As a gemstone, it has gained popularity for those seeking sustainable and conflict-free options. My recommendations for those interested in purchasing moissanite focus on finding reputable vendors who provide high-quality stones with transparent grading reports. This allows for an informed choice in selecting the best quality moissanite that aligns with individual preferences and values.


Understanding Moissanite

Moissanite is a gemstone steeped in history and discovery, boasting unique qualities apart from diamonds, such as its composition—silicon carbide—that endows it with remarkable hardness and brilliance.

History of Moissanite

I find the origin of moissanite both intriguing and relatively recent in the broad realm of gemstones. Natural moissanite was first discovered by Dr. Henri Moissan in 1893 while examining rock samples from Meteor Crater in Arizona. Mistaken initially for diamond, it was later identified as silicon carbide, a rare mineral. Today, most moissanite is lab-created, imparting sustainable perfection to this durable gem.  

Moissanite vs. Diamonds

Aspect Moissanite Diamonds
Composition Silicon carbide (SiC) Carbon (C)
Hardness (Mohs scale) 9.25 10
Brilliance & Fire Greater brilliance and fire due to higher refractive index. Renowned for brilliance and fire but typically slightly lower than moissanite.
Color Generally near-colorless to faint yellow or greenish hue. Range of colors including colorless, near-colorless, and fancy colors.
Price Generally more affordable than diamonds. Varies widely based on the 4Cs (color, clarity, cut, carat weight).
Origin Laboratory-created (synthetic) moissanite is common. Natural and lab-created (synthetic) diamonds available.
Environmental Impact Considered more environmentally friendly as it's lab-created. Mining diamonds has environmental considerations.

When I compare moissanite and diamonds, several distinct differences surface. While diamonds are traditionally known for their "fire" and hardness—ranking a perfect 10 on the Mohs scale—moissanite is not far behind, with a Mohs scale ranking of 9.25 to 9.5. Moissanite's refractive index is higher than a diamond's, which gives it more sparkle; however, its dispersive power, which creates the characteristic "fire," is nearly 2.4 times more than that of diamonds, leading to increased brilliance.

Physical and Chemical Properties

My assessment of moissanite's physical and chemical properties reveals a robust and extraordinary gemstone. Chemically, it is composed of silicon carbide, a compound with a hexagonal crystal structure that contributes to moissanite's exceptional hardness. It is resistant to scratching, chipping, and abrasions, making it an excellent choice for jewelry that endures daily wear. Its thermal conductivity is closer to that of diamonds than any other gemstone, presenting similarities that skilled gemologists can differentiate.

Evaluating Moissanite Quality

When I examine moissanite quality, I focus on the renowned 4C's—Color, Clarity, Cut, and Carat Weight—just as one would with diamonds. Each of these factors is crucial in determining the overall appearance and value of moissanite stones.

The 4C's of Moissanite

Color: Moissanite tends to be classified from colorless to near-colorless. The less color a moissanite has, the higher its value. A colorless moissanite closely mimics the appearance of a high-quality diamond.

Clarity: Clarity in moissanite refers to the absence of internal imperfections or inclusions. Moissanite with a high clarity grade has fewer visible inclusions, which enhances its sparkle and perceived quality.

Color and Clarity

  • Color Grade: The scale ranges from D to K, with D being completely colorless, and is a prime determinant in quality.

    • D-F: Colorless; premium quality.
    • G-I: Near-colorless; excellent value, with slight color detected by an expert.
  • Clarity Grade: Ranges from Flawless to Included, with Flawless being the most desirable.

    • FL-IF: Flawless to Internally Flawless; no visible inclusions or blemishes.
    • VVS1-VVS2: Very, Very Slightly Included; inclusions hard to see under 10x magnification.

Cut and Carat Weight

  • Cut: This affects the stone's brilliance and is not to be compromised. An excellent cut moissanite will have superb brilliance.
  • Carat Weight: Though it impacts size, it does not directly relate to quality. However, the larger the moissanite, the more apparent any inclusions or color tints might be.

When evaluating cut, the quality grade can range from excellent to poor. A stone with a rating of very good represents a balanced compromise between size and quality, while fair or poor cuts do compromise the stone's brilliance for size.

When considering carat weight, I always remember that moissanite is lighter than diamonds, so they are often sold by their size in millimeters rather than by weight. This must be taken into account in order to accurately compare the size of moissanite to that of diamonds.

Hardness and Everyday Wear

Moissanite ranks impressively high on the Mohs scale of hardness, just below diamond, which is the hardest known mineral. With a score of 9.25, moissanite is exceptionally resistant to scratches and abrasions, making it ideal for everyday wear. Even with frequent use, I observe that the stones retain their sparkle and structure over long periods. This resistance to wear implies that moissanite jewelry can be a stalwart companion in daily activities without the fear of easy damage.

Care Instructions

To ensure moissanite maintains its luster, I recommend a simple, regular cleaning routine:

  1. Use a soft-bristled brush to gently remove any dust or dirt.
  2. Prepare a solution of warm water and mild dish soap.
  3. Soak the moissanite jewelry in the solution for 20-30 minutes.
  4. Rinse thoroughly with clean water.
  5. Dry with a soft, lint-free cloth.

For a more thorough clean, especially if the moissanite has been exposed to makeup, oil, or lotions, consider an ultrasonic cleaner. However, consulting the jewelry provider before using an ultrasonic cleaner is advised, as certain settings may not be suitable. My experience shows that these care steps are all that is required to maintain the shine and clarity of moissanite stones.

Brilliance and Fire

I find that when assessing the quality of moissanite, the two characteristics that often stand out are its brilliance and fire. These are essential qualities that contribute to moissanite's popularity as a gemstone.

Understanding Moissanite's Sparkle

Moissanite's sparkle is primarily due to its exceptional brilliance, which is the gemstone's ability to reflect white light. Its composition of silicon carbide allows for a refractive index that is higher than that of diamond, which is why, when I compare them side by side, the moissanite often exhibits more sparkle. Moissanite's unique crystal structure also contributes to its fire, which is the breaking of light into the colors of the spectrum. I've observed that moissanite often shows more fire than a diamond due to its higher dispersion.

Comparing Brilliance

When comparing moissanite to other gemstones, it becomes clear that moissanite offers an exceptional brilliance that is unrivaled by most other stones. This brilliance can be quantified and I've seen reports like one on ResearchGate that delve into the specifics of how moissanite's body color grade correlates with its perceived fire and brightness. The cut of the moissanite also plays a pivotal role in its brilliance, and cut quality directly impacts the display of sparkle and light performance within the stone. Therefore, when comparing, it's crucial to consider how the cut influences the brilliance that I perceive in the moissanite.

Moissanite Varieties and Brands
