What is Moissanite?

Moissanite: A Comparative Analysis

Moissanite is a naturally occurring mineral that has recently gained popularity as an alternative to diamonds. As a semiprecious gemstone, it possesses similar characteristics to diamonds, such as durability, brilliance, and fire. Its unique optical properties make it a highly sought-after gemstone in jewellery.

Not only does moissanite possess a high refractive index, but it also exhibits double refraction, which results in an extraordinary sparkle. This optical brilliance, paired with its hardness and toughness, makes moissanite an attractive option for those seeking a diamond-like gemstone at a more affordable price point.

While moissanite shares some similarities with diamonds, it does have a few distinct differences. Unlike diamonds formed deep within the earth's mantle over billions of years, moissanite is found in limited quantities in meteorites. Its scarcity contributes to its exclusivity and desirability.

Diamonds, on the other hand, are naturally occurring. Moissanite is considerably cheaper than diamonds, making it a budget-friendly alternative. While diamonds are the hardest mineral and extremely durable, moissanite is a close second on the Mohs hardness scale and is scratch-resistant. Additionally, moissanite has more brilliance and sparkle than diamonds, providing a rainbow-like effect.

Is moissanite suitable for engagement rings?

Yes, moissanite is a great option for engagement rings. It is a durable stone that can withstand everyday wear and tear. Its hardness on the Mohs scale makes it unlikely to scratch easily. Moissanite also offers a stunning sparkle and brilliance, making it a visually appealing choice for engagement rings. Furthermore, moissanite is considerably more affordable than diamonds, allowing you to get a larger carat size or higher quality stone within your budget.

Can moissanite be mistaken for a diamond?

Moissanite can look remarkably similar to a diamond, especially to the untrained eye. It possesses a similar brilliance and sparkle. However, some differences can help distinguish between the two. Moissanite has more fire and dispersion, resulting in a greater display of spectral colours when the stone is rotated. Diamonds, on the other hand, reflect whiter light. Additionally, moissanite may have had a yellowish or greenish tint in the past, but manufacturers have perfected the creation process, allowing for colourless moissanite options.

What are the advantages of choosing moissanite over diamonds?

There are several advantages to choosing moissanite over diamonds for engagement rings.
