Natural Diamonds, Lab-Grown Diamonds, and Moissanites: What's the Difference?

When it comes to choosing the perfect stone for your jewelry, the options can be overwhelming. Three of the most popular choices are natural diamonds, lab-grown diamonds, and moissanites. Each type has its own unique characteristics, advantages, and considerations. Let's dive into the details to help you make an informed decision.

Natural Diamonds

Natural diamonds are created deep within the Earth's mantle over billions of years under extreme pressure and heat. They are mined from various locations around the world, making each diamond a rare and unique piece of nature. Known for their exceptional hardness, natural diamonds score a perfect 10 on the Mohs scale, making them the hardest known natural material. They exhibit remarkable brilliance and fire, thanks to their unique crystal structure, which enhances their desirability and market value. Due to their rarity and natural formation, natural diamonds are often seen as timeless symbols of luxury and status. However, they are generally more expensive than lab-grown diamonds and moissanites, and ensuring that your diamond is conflict-free and sourced from ethical mining practices is crucial.

Lab-Grown Diamonds

Lab-grown diamonds are created in controlled laboratory environments using advanced technological processes that mimic the natural conditions under which diamonds form in the Earth. These diamonds have identical physical, chemical, and optical properties to natural diamonds, including a hardness rating of 10 on the Mohs scale. Lab-grown diamonds offer a more budget-friendly option without sacrificing quality, as they are typically less expensive than natural diamonds. Additionally, they are considered more environmentally friendly because they avoid the ecological disruption caused by mining. While growing in popularity, lab-grown diamonds may not carry the same traditional prestige as natural diamonds, but they provide an excellent alternative for those prioritizing sustainability and cost-efficiency.


Moissanite is a naturally occurring silicon carbide discovered in a meteorite crater, but most moissanites used in jewelry today are lab-created due to their rarity in nature. With a hardness rating of 9.25 on the Mohs scale, moissanites are very durable and suitable for daily wear. They display more brilliance and fire than diamonds, often appearing more sparkly under light. However, while very similar to diamonds, moissanites can exhibit a different type of sparkle, sometimes described as a “rainbow effect,” which some people love, while others may prefer the classic look of diamonds. Moissanites do not hold the same market value as diamonds, but they offer excellent beauty and durability for their price.

Making Your Choice

Choosing between natural diamonds, lab-grown diamonds, and moissanites depends on your personal preferences, budget, and values. If budget is a concern, lab-grown diamonds and moissanites offer high-quality options at a lower price point. If you value a natural formation and traditional prestige, a natural diamond might be the best choice. For those prioritizing sustainability, lab-grown diamonds or moissanites could be more appealing. Additionally, consider the type of brilliance and sparkle you prefer; diamonds offer classic brilliance, while moissanites provide a unique and often more vibrant sparkle.
