When selecting the ideal gemstone, many people are uncovering the allure and sparkle of Moissanite, a remarkable alternative to classic diamonds. But what really distinguishes these two stones? We believe that understanding your jewellery is the key to appreciating its craftsmanship and meaning.
Origin and Creation
The most significant difference between Moissanite and Diamond lies in their origin.
Diamonds are formed naturally under intense heat and pressure deep within the Earth’s mantle, taking billions of years to develop before being brought to the surface through volcanic activity. This process makes them rare, but also associated with environmental impact due to mining.
Moissanite, in contrast, has a celestial origin. It was first discovered by French chemist Henri Moissan in 1893 in a meteor crater, leading scientists to recreate its natural beauty through advanced laboratory methods. Today’s Moissanite is entirely lab-grown, ensuring it is ethically sourced, sustainable, and conflict-free, while still capturing the same mesmerizing sparkle that first fell from the stars.
Brilliance and Fire
When it comes to brilliance, the Moissanite outshines almost every other stone, including diamonds. Brilliance refers to how well a gemstone reflects white light. Moissanite’s refractive index ranges from 2.65 to 2.69, compared to a diamond’s 2.42, giving Moissanite a more intense sparkle.
Fire refers to the rainbow-like flashes of colour seen when light passes through the stone. Moissanite’s fire dispersion is 0.104, nearly double that of a diamond (0.044). This means it produces a livelier, more colourful sparkle that is instantly eye-catching. This combination of brilliance and fire gives Moissanite its signature radiance.

Value and Affordability
Diamonds come with a high price tag due to their rarity and mining process. Moissanite, on the other hand, offers the same luxurious look at a fraction of the cost. This allows you to invest in fine jewellery without compromise.
Durability and Everyday Wear
Moissanite is known for its exceptional strength and resilience, making it perfect for everyday wear. Ranking 9.25 on the Mohs hardness scale, it’s one of the hardest known gemstones, second only to diamond. This means your Moissanite jewellery resists scratching, maintains its flawless polish, and retains its brilliance for years to come. Whether worn daily or saved for special occasions, each piece remains as radiant as the day you received it.
Sustainability and Ethics
Unlike mined diamonds, Moissanite is lab-grown and eco-friendly. Its free from the environmental and ethical concerns associated with traditional diamond mining. Every piece is crafted with sustainability in mind, ensuring that your sparkle aligns with your values.
Conclusion
Choosing Moissanite means embracing modern luxury: brilliance without compromise. With its exceptional sparkle, lasting durability, and ethical origins, it’s no wonder Moissanite has become the stone of choice for the new generation of jewellery lovers.
