Moissanite vs Diamond: What’s the Difference and Which Should You Choose?
Choosing between moissanite and diamond can feel a bit like picking between two dazzling stars — both brilliant, yet each with its own unique charm.
In short: Diamonds are harder (Mohs 10 vs Mohs 9.25) and more valuable; moissanite has a higher refractive index (2.65 vs 2.42) so it throws more rainbow fire. A 1.00ct round moissanite costs around £150-£400 versus £900-£1,800 for a lab-grown diamond and £6,500+ for a mined diamond. Moissanite suits budget-conscious buyers wanting maximum sparkle; diamond suits buyers prioritising long-term value and tradition.
Whether you're on the hunt for the perfect engagement ring or simply curious about these gemstones, understanding their differences is key.
Let’s dive into the world of moissanite and diamonds to help you make an informed choice.
Understanding Diamonds
Diamonds have long been the epitome of luxury and romance.
Formed deep within the Earth's mantle over billions of years, these gems are composed entirely of carbon atoms arranged in a crystal lattice, giving them exceptional hardness and brilliance.
Their lasting appeal has made them a staple in jewellery, especially for significant milestones like engagements and anniversaries.

Unveiling Moissanite
Moissanite, on the other hand, has a celestial origin.
Discovered in 1893 by French scientist Henri Moissan in a meteor crater, this gemstone is made of silicon carbide.
