The 5 Cs of Moissanite vs Diamonds: A Comprehensive Guide

When it comes to choosing a gemstone for that special occasion, diamonds have traditionally been the go-to choice. However, moissanite as a high-quality alternative to diamonds is rapidly emerging. In this guide, we delve into the 5 Cs that define both diamonds and moissanite, with a special focus on the unique fifth C—Confidence—that moissanite brings to the table.

Moissanite Colour vs. Diamond Colour

Diamonds are traditionally graded on a colour scale from D (colourless) to Z (yellow). Moissanite, however, should be evaluated on its own merits. It comes in a variety of shades, including colourless, near-colourless, and tinted. For more details on moissanite colour grading compared to diamonds, check out our colour stone chart.

Moissanite Cut vs. Diamond Cut

The cut of a gemstone plays a crucial role in its brilliance and fire. While diamonds have specific ideal cutting angles, moissanite requires a different approach to maximise its unique refractive properties. Learn more about the quality cuts in our Majestic Moissanite range.

Clarity: Moissanite vs. Diamond

Diamonds are graded for clarity based on a range from Flawless to Included. Moissanite, often created in controlled environments, generally has fewer inclusions than diamonds. When they do occur, they are typically needle-like and less obstructive to light. For more on moissanite and diamond grading information, visit our grading information page.

Carat Size: Moissanite and Diamond

Moissanite is visually proportionate to typical diamond-carat weights but is approximately 10% to 15% lighter than diamonds. For more information on how moissanite carat sizes compare to diamonds, check out our moissanite price guide.

Confidence: The 5th C in Moissanite

What sets moissanite apart from diamonds is the fifth C—Confidence. Not only does each stone come with a Lifetime Warranty for quality assurance, but its lab-grown nature also ensures a more reliable and ethical supply compared to diamonds.


When it comes to making an informed choice between a diamond and moissanite, understanding the 5 Cs is crucial. Moissanite not only matches diamonds in terms of the traditional 4 Cs but also offers an additional layer of Confidence. With its unique properties and the added assurance of a Lifetime Warranty for quality moissanite, choosing moissanite is a decision you can make with confidence.
