Diamond Engagement Rings vs. Moissanite: Which Is Better for You?

Choosing the perfect engagement ring is one of the most exciting—and sometimes nerve-wracking—decisions you’ll make in your life. Among the sea of options, two popular choices stand out: diamond and moissanite. Both are stunning in their own right, but which one is truly better for you? In this article, we’ll dive into the characteristics of both gemstones, comparing everything from brilliance to cost, so you can make an informed decision that you’ll cherish forever.

In short: Diamond (Mohs 10) is harder than moissanite (Mohs 9.25-9.5) and has classic fire/brilliance. Moissanite shows more rainbow flash but at larger sizes can look obviously different from diamond. Lab-grown diamond now costs almost as little as moissanite (£800-£1,200 for 1ct) — making moissanite's price advantage much smaller than it was five years ago.

What Are Diamonds and Moissanite?

Diamonds are the traditional go-to for engagement rings. Formed under intense heat and pressure deep within the Earth, diamonds are renowned for their unmatched hardness and lasting appeal. They have been symbols of love and commitment for centuries, often passed down through generations as family heirlooms.

Moissanite, on the other hand, is a relatively new contender in the world of gemstones. Originally discovered in a meteorite by Dr Henri Moissan, this gemstone is composed of silicon carbide. Today, most moissanite is lab-created, offering an ethical and sustainable option without sacrificing beauty. If you’re interested in sustainable options, consider exploring our lab-grown diamonds.
