Moissanite vs. Diamond: What are the Key Differences?


Moissanite is a gemstone that is made from silicon carbide and is often known as the "gemstone born from the stars." It was first discovered in 1893 by Nobel Prize-winning chemist Henri Moissan inside a meteor crater in Canyon Diablo, Arizona. At first, the crystals were believed to be diamonds, but in 1904 Moissan identified them as silicon carbide — a completely different mineral that would later be named moissanite in his honor.

Natural moissanite is incredibly rare. For many years, it was found only within meteorites until geologists later discovered traces of it within the Earth's mantle near Wyoming.

Today, moissanite is responsibly created in advanced laboratory environments, making it a modern alternative to mined diamonds. Because it is lab-grown rather than extracted from the earth, moissanite is fully traceable and avoids the environmental impact associated with traditional mining. This results in a more sustainable gemstone with a smaller carbon footprint while still offering exceptional brilliance, durability, and beauty.

As demand for ethical and affordable luxury continues to grow, moissanite has become an increasingly popular choice in jewelry — especially for engagement rings and timeless everyday pieces.



No, moissanite is not a diamond. Although moissanite is designed to closely resemble the appearance of a diamond, the two stones are compositionally different. Diamonds are made entirely of carbon, while moissanite is created from silicon carbide in laboratory environments.

To the naked eye, moissanite and diamonds can appear very similar, but moissanite has a higher refractive index, meaning it reflects more colorful rainbow-like sparkle, often referred to as “fire.” Diamonds, however, are slightly harder and rank a perfect 10 on the Mohs hardness scale, while moissanite ranks at 9.25 — making it exceptionally durable for everyday wear.

Both gemstones are known for their brilliance, sparkle, and excellent durability, but they each possess unique characteristics that set them apart.



  1. Ethically Created
    Moissanite is lab-grown, offering a more environmentally conscious alternative to traditionally mined gemstones.

  2. Exceptional Value
    Moissanite delivers the luxurious look of fine jewelry at a more accessible price point compared to many other gemstones.

  3. Made to Last
    With a 9.25 rating on the Mohs hardness scale, moissanite is highly durable and perfect for everyday wear.


  1. Is Moissanite a fake diamond?
    No, moissanite is not a fake diamond — it is a distinct gemstone with its own unique composition and characteristics. While it closely resembles the appearance of a diamond, moissanite is made from silicon carbide rather than carbon, giving it its own exceptional brilliance and beauty.

  2. How long can a moissanite ring last?
    Similar to a diamond, moissanite is designed to last a lifetime. Rated 9.25 out of 10 on the Mohs hardness scale, moissanite is exceptionally durable and built to maintain its beauty for decades with proper care.

  3. How is Moissanite made?
    Lab-created moissanite—the most widely available form of this gemstone—is produced by combining its basic chemical components. The material is then subjected to intense heat and pressure, allowing the crystal to form into a finished stone.

  4. How should I clean my Moissanite ring?
    Moissanite rings are best cleaned with using mild soap or a gentle jewelry cleaner. Soaking them briefly in a soft cleaning solution can help restore their brilliance and bring cloudy stones back to a bright, sparkling shine.

    In conclusion, both moissanite and diamonds come with their own advantages and disadvantages, and the choice between them ultimately depends on personal preference, budget, and lifestyle. While diamonds have a long-standing reputation for their natural rarity and beauty, moissanite provides a brilliant and affordable alternative for those who want the look of a diamond at an incredible value.
