Although diamonds remain one of the most popular choices for engagement ring centre stones, more and more couples are considering other stone alternatives for their rings. Moissanite, another clear, white and brilliant gemstone, is one of the most in-demand diamond alternatives due to its similarity in durability, brilliance, and beauty. 

Despite the distinctive origins of diamonds and moissanite, the two gemstones have many things in common. The Gemological Institute of America (GIA) deems moissanite the closest diamond imitation due to its similar refractive index and colourless properties, but the two gemstones do vary in many other ways. Each gem comes with its own benefits, so it’s important to identify what you are looking for to determine which stone best aligns with your needs and preferences.

Understanding the key differences between moissanite vs diamond engagement rings can help you make an informed decision about the best option for you and your partner. 

Compare the Brilliance

A diamond is a mineral composed of pure carbon, whereas moissanite is lab-grown silicon carbide. Both gemstones can be grown in a lab. 

Although it is challenging to detect the different qualities of diamond and moissanite, these qualities play a critical role in your decision process. Moissanite has gained traction over the years due to its characteristics of being near colourless and free of visible inclusions. 

Diamonds are well-known for their extreme hardness, unmatched brilliance, and rich sentimental value. But moissanite has its own unique qualities, including its unique rainbow fire. A gemological property known as dispersion determines how a stone sparkles. Dispersion occurs when white light enters moissanite or diamond, splits into the rainbow of colours, and bounces back to reflect the light at a different speed. Moissanite’s dispersion is 0.104, 2.4 times the dispersion of diamond (0.044), indicating that you may see more rainbow colours in the sparkle of moissanite than a diamond.

Choose the One That Fits Your Budget

Whiles some view a diamond ring as an ‘investment,’ others are drawn to the fact that moissanite allows you to maximize your budget and achieve a larger stone at a lower cost. 

If you’re less focused on the status quo and more concerned with the price, you can select moissanite without comprising on cut, colour, or clarity. 

Consider the Range of Quality

Both diamond and moissanite can be created with varying quality and standards, and this is where a professional custom jeweller can play a critical role. Ask your jeweller the origin of a diamond or moissanite to ensure a quality end product. A reputable jeweller will be transparent about the production and inform you where their materials are sourced from. 

Some of the essential quality aspects of moissanite is its colour, clarity and cut. These variables can range depending on the manufacturer. A high-quality manufacturer would provide colourless and near-colourless options that are free of visible inclusions and beautifully cut. Asking about three factors will ensure a beautiful end product in your engagement ring.

There is no right or wrong answer while selecting a gemstone for yourself or your partner. Diamonds and moissanite are both great options with distinctive yet similar features, allowing you to prioritize the factors that matter to you most.
