What is the Difference Between Moissanite and Diamonds? Your Guide

At Pompeii3, we believe knowledge is power, especially when it comes to jewelry shopping. Today, we’re exploring the dazzling world of two sought-after gemstones that often get mistaken for each other – moissanite and diamonds. By the end of this blog, you'll be able to understand the differences between moissanite and diamonds and decide which gem truly resonates with your style. So, let's dive in!

What are Diamonds?

In our comparison of Moissanite vs diamonds, we will start out with natural diamonds. These are the classic and traditional choice. Diamonds are renowned for their brilliance, hardness, and enduring symbol of love. They are formed deep within the Earth's mantle under conditions of intense heat and pressure, taking billions of years to form. This complex creation process creates key differences between Moissanite and diamonds, giving the latter their unique value.

The quality of a diamond is evaluated based on the "Four Cs" - Cut, Clarity, Color, and Carat weight. Cut influences the diamond's brilliance, while clarity refers to the presence of inclusions or flaws. The color scale for diamonds ranges from D (colorless) to Z (yellow or brownish), and carat weight determines its size.

Lab-Grown Diamonds

Lab-grown diamonds are a fantastic alternative to natural diamonds. They are real diamonds in every sense, sharing the same physical, chemical, and optical properties as their natural counterparts. The only difference? Their origin.

Created in highly controlled laboratory environments, these diamonds are formed by replicating the natural diamond-growing process. The result is a diamond that is visually, chemically, and physically identical to those grown beneath the Earth's surface.

What is Moissanite?

Moissanite, on the other hand, is a gemstone born from the stars. Quite literally! It was first discovered by French scientist Henri Moissan in 1893 in a crater created by a meteorite that fell to Earth. He initially mistook them for diamonds due to their exceptional sparkle and hardness. However, Moissanite is a naturally occurring silicon carbide, quite rare in nature, so most Moissanite gems you see today are lab-created, offering superior control over their quality.

When comparing Moissanite vs diamonds, Moissanite scores a 9.25 on the Mohs hardness scale, making it one of the hardest substances on Earth, just below diamonds. This gemstone is known for its high refractive index, which gives it more fire (rainbow-colored flashes of light) than diamonds. So, if you're all about that sparkle, this might be an appealing difference between Moissanite and diamonds!

Comparing Diamonds & Moissanite

Brilliance

Both diamonds and Moissanite are loved for their dazzling brilliance, but one difference between them lies in how they refract light. Diamonds exhibit a balanced combination of white and colored light, known as brilliance and fire, respectively. Moissanite displays more fire (rainbow flashes), which makes them even more brilliant than diamonds. Some find this appealing, while others prefer the more subdued fire of a diamond. 

Hardness

Diamonds are the hardest known mineral and rate a perfect 10 on the Mohs hardness scale. When comparing Moissanite vs diamonds, Moissanite isn't far behind with a rating of 9.25, making it one of the hardest substances on Earth and excellent for everyday wear.

Color

Diamonds range from colorless to shades of yellow or brown and even come in fancy colors like blue and green. Moissanite, however, is not entirely colorless and can project a yellow or grayish hue under certain lights. Today, colorless options are available but might carry a slightly higher price tag.

Price

Perhaps the most significant difference between diamond and Moissanite is the price. Moissanite is significantly less expensive than diamonds, but lab-grown diamonds can be a great middle-ground option. This price difference doesn't reflect quality but rather the rarity and market demand for natural diamonds. 

Sustainability

Given that most Moissanite is lab-created, it has minimal environmental impact compared to natural diamond mining. For those looking for a more eco-friendly choice, this difference between Moissanite and diamonds makes it an excellent option. 

Choosing Between Diamond & Moissanite

The choice between diamond and Moissanite jewelry ultimately comes down to personal preference. If you are after a classic, timeless gem with unmatched hardness, a diamond is for you. If you prefer a highly brilliant yet budget-friendly and ethical gem, then consider Moissanite.

Remember, whether you opt for a fiery Moissanite or a classic diamond, the most important factor is that your chosen gem reflects your personal style and values. After all, the differences between these gemstones give each a unique charm, and beauty, as they say, is in the eye of the beholder!
