So what are the differences?

The main differences between moissanite and a diamond are their composition, physical appearance, cost, and environmental impact. Here are a few key differences:

1. Composition: Moissanite is composed of silicon carbide, whereas diamonds are composed of pure carbon. This gives both stones different physical and optical properties.
2. Appearance: Both moissanite and diamonds can look very similar to the naked eye, but there are some differences. Moissanite has a higher refractive index than diamond, which means it reflects more light and has a greater "sparkle" or "fire". Some people describe this as a "disco ball" effect. Moissanite can also have more color than a diamond, but it has a different color distribution than diamonds.
3. Hardness: Diamonds are the hardest substance on earth, with a ranking of 10 on the Mohs scale of hardness. Moissanite ranks at 9.25 on the same scale, making it a very durable and long-lasting stone.
4. Cost: Moissanite is generally much less expensive than diamonds. While the price can vary based on quality and size, moissanite can be up to 90% less expensive than a diamond of the same size and quality.
5. Environmental Impact: Moissanite stone is better for the environment because it is a lab-grown stone and does not require mining. Diamond mining can lead to deforestation, water pollution, soil erosion, habitat destruction, and many other negative effects on the environment.

In conclusion, while moissanite and diamonds may look similar, they have different compositions, physical properties, and price points. Ultimately, which stone is right for someone will depend on their personal preferences, budget, and lifestyle.
