What is Moissanite?

Moissanite is a gemstone made from silicon carbide. First discovered in a meteor crater, it’s now lab-created for jewellery use. Known for its exceptional sparkle, moissanite emits rainbow-like flashes due to its high refractive index (2.65–2.69).

Pros of Moissanite:

• More brilliance (fire)

• Very durable (Mohs 9.25)

• Affordable

• Ethically sourced

Cons:

• Can appear too sparkly (some say “disco ball” effect)

• Not a diamond (for traditionalists)

What is a Lab Grown Diamond?

Lab grown diamonds are real diamonds created in controlled environments using either HPHT (High Pressure High Temperature) or CVD (Chemical Vapor Deposition) methods. They are chemically and visually identical to mined diamonds.

Pros of Lab Grown Diamonds:

• Same look and feel as mined diamonds

• Lower cost (30–50% less than natural diamonds)

• Ethical and eco-conscious

Cons:

• Slightly more expensive than moissanite

• Lower resale value compared to mined diamonds
