I delved deep into the world of precious stones, not seeking diamonds or sapphires, but something far more intriguing. What Is Moissanite? This was the question that consumed my thoughts.

This gem, both rare and bewitching, has its roots in the cosmos, originating from meteorites that graced our planet eons ago. Resembling a diamond, but with its own unique charm and story, Moissanite became the star of my exploration, dazzling me with its brilliance and history.

What is Moissanite?

Recently, I stumbled upon a name that echoed with celestial wonder: Moissanite. Not your typical gemstone, Moissanite stands apart with an origin story that feels plucked from the pages of a sci-fi novel. As I dug deeper, I learned that it was first discovered in a meteorite crater in Arizona by Dr. Henri Moissan in 1893. Imagine that – a gem born from the stars!

Its appeal isn’t just celestial. Holding a piece in my hand, I was struck by its fiery sparkle. Often compared to diamonds for their brilliance, Moissanite boasts a refractive index even higher than the famed jewel. Yet, it’s not just a diamond imposter; it carries its own unique allure and charisma. And while today’s market offers lab-grown diamonds for jewelry enthusiasts like me, the tale of its space-touched origins continues to captivate my imagination.

Moissanite vs. Diamond

The price of moissanite is generally lower than that of natural diamonds, making it a more affordable option for those seeking a diamond alternative.

In terms of durability, moissanite is known to be one of the toughest gemstones, making it suitable for everyday wear as engagement rings.


Moissanite stones present a compelling cost advantage over diamonds, offering those desiring a substantial white gemstone a pocket-friendly alternative. O’Connell notes that a moissanite gem costs roughly one-tenth of a comparable mined diamond’s price. Intriguingly, when scaling up in carat weight, superior quality moissanite often proves more economical than lesser quality, smaller diamonds.

For those yearning for the allure of a pristine, clear diamond but are tethered by budgetary limits, moissanite emerges as a dazzling alternative. In essence, moissanite’s affordability ensures that beauty and brilliance needn’t be sacrificed for cost considerations.


On the Mohs hardness scale, diamonds top the chart at 10, showcasing their unparalleled durability. Moissanite, impressively, ranks between 9.25 and 9.5, making it among the hardest gemstones. Ideal for daily-worn engagement rings, moissanite’s resilience against breakage and chipping ensures it retains its brilliance and integrity.

When contrasting moissanite with diamonds regarding endurance, both gems exhibit remarkable longevity, preserving their structure over extended periods. This endurance positions moissanite as a compelling, durable alternative to diamonds for those aiming for lasting brilliance.


The first time I studied moissanite closely, I was entranced by its unmatched brilliance and fire, surpassing even diamonds. This is attributed to its double refractive nature, causing light to split into twin rays, creating a mesmerizing display of spectral colors. This phenomenon gives moissanite that exceptional rainbow effect, unlike diamonds which primarily reflect whiter light. Additionally, the way moissanite is cut differs from diamonds, tailored to its unique optical traits.

These cutting methods optimize the light that dances through, resulting in an enchanting sparkle. While genuine diamonds boast their own luminance, reflecting white light with clarity, moissanite offers a distinctive and intense radiance that truly captured my attention.

When assessing the quality of diamonds and moissanite, color grading plays a pivotal role. The hue of these gemstones significantly influences their aesthetic appeal and worth. Here are three crucial insights on their color attributes:

1. Pure and Pristine: Diamonds categorized within the D-F spectrum are deemed colorless, enhancing their desirability and value. Similarly, today’s advanced techniques allow for the creation of premium moissanite with a clear, colorless look.

2. Hint of Yellow: Descending the color chart, both diamonds and moissanite might display a yellow undertone, potentially diminishing their shimmer and radiance.

3. Standardized Evaluation: The Gemological Institute of America (GIA) establishes the benchmark for diamond color grading, with specialists examining each gem’s shade and depth in a standardized lighting environment.

How Is Moissanite Graded?

As I learned more about this gem, I quickly realized that its beauty is gauged through three key facets: clarity, cut, and carat weight. First, clarity. As someone who appreciates perfection, I was drawn to the fact that moissanite usually appears eye-clean, devoid of discernible flaws to the unaided eye. 

Then there’s the cut. The gem’s faceting intrigued me, as its cut can greatly influence its shimmer. A masterfully cut moissanite dazzles, reflecting light in ways that amplify its inherent fire and scintillation. 

Carat weight, representing the gem’s size, also spoke to its value. Bigger, in this context, often translates to more prized.

However, as I compared it to my knowledge of diamonds, I noticed a distinction in color grading. Diamonds have a spectrum from D to Z, while moissanite is mainly branded as colorless or near-colorless. A colorless moissanite echoes the luminance of a DEF diamond, whereas its near-colorless counterpart mirrors a GHI diamond.

So, my lesson? To truly appreciate a moissanite’s splendor, one must look closely at its clarity, cut, and carat weight. Each element defines its allure and worth.
