Moissanite vs. Diamond: Which Gem Should You Choose?

In the realm of jewellery, a critical choice that must be made is between moissanite and diamond. For the uninitiated, these two stones might appear indistinguishable but, upon closer inspection, they reveal distinct differences that impact not only their appearance but also their value. In this comprehensive guide, we elucidate the major differences between these two gemstones, focusing on aspects such as price, appearance, and durability, to help you make an informed decision when selecting your engagement ring.

What is Moissanite?

Moissanite, discovered in 1893 by scientist Henri Moissan, is a rare gem originally found in a meteorite crater in Arizona. Initially believed to be a diamond, subsequent analysis revealed it to be composed of silicon carbide. Its extraterrestrial origins make natural moissanite exceedingly rare, with most stones today being lab-created to emulate the appearance of diamonds.

Origin of Moissanite

While natural moissanite has been discovered in the United States and Russia, it predominantly hails from space. Modern moissanites are synthesised in laboratories, designed to replicate the allure of diamonds. However, their composition and visual properties diverge significantly from authentic diamonds. Those seeking an eco-friendly gemstone might find moissanite appealing, though for those desiring the unmatched brilliance and genuine value of diamonds, lab-grown diamonds present a commendable alternative. At our establishment, we source conflict-free natural diamonds and eco-friendly lab-grown diamonds.

Can You Differentiate Between Moissanite and Diamond?
– Ralph Waldo Emerson

At first glance, moissanite and diamond may appear similar, but upon closer examination, differences in chemical composition, colour, transparency, brilliance, and hardness become evident.

Colour: Moissanite vs. Diamond

Diamonds are graded on a colour scale from D (nearly colourless) to Z (with a noticeable hue). This scale significantly influences a diamond’s price; the purer the diamond, the higher its value. In contrast, moissanite lacks a formal colour grading system. It often exhibits yellow, green, or grey tints depending on the lighting. If compared to the GIA diamond scale, moissanite would most frequently rate around K, indicating a slight visible colour. Notably, moissanite can change colour when heated to 65°C.

Clarity: Moissanite vs. Diamond

Clarity refers to a stone’s lack of imperfections and inclusions, affecting its transparency. Similar to diamonds, moissanites are not entirely flawless but since they are usually lab-created, they are often free from visible inclusions to the naked eye. While diamonds might display inclusions and imperfections, we ensure that the diamonds adorning our jewellery, engagement rings, and wedding bands are eye-clean.

Brilliance: Moissanite vs. Diamond

Brilliance refers to the light reflection within a stone, contributing to the dazzling effect diamonds are renowned for. Light refraction varies among gemstones depending on their cut. Generally, moissanite exhibits substantial brilliance and disperses light effectively. However, its sparkle, though pronounced, lacks the intensity and clarity of a diamond’s radiance.

Hardness: Moissanite vs. Diamond

The hardness of a gemstone is quantified using the Mohs scale, ranging from 1 (least hard) to 10 (hardest). Diamonds, being the hardest known material, score a perfect 10, making them exceedingly resistant to scratches and damage. Moissanite, with a rating of 9.25, is slightly softer, thus more prone to scratches or damage. Consequently, natural and lab-grown diamonds boast superior durability compared to moissanite.

Why is Moissanite Less Expensive than Natural Diamonds?

Moissanite can be purchased at a fraction of the cost of natural diamonds, but is it worth it? This question frequently arises, especially concerning the price of an engagement ring. While moissanite is indeed less costly, it does not possess long-term value or the authentic and rare essence of a natural diamond.

Conclusion

Though moissanite is crafted to resemble a diamond, it is not a natural diamond. So, which stone should you choose? The decision ultimately lies with you. If you seek a heirloom piece to pass down to future generations, such as the diamond-set engagement rings in our Solitaire collection, diamonds are the ideal choice. Conversely, if budget is a significant consideration, moissanite represents a sound alternative. Ultimately, the most important factor is personal preference. Rest assured, whichever stone you select, it will be the perfect gem for you.
