Paras Jhamb 0 comments

Silicon carbide-based moissanite mimics diamonds but has a completely different origin. Henri Moissan wrongly found it as a diamond in a meteor crater in 1893. All Moissanite accessible today is lab-made since each stone takes months to grow.

Due to their time-taking formation deep in Earth’s surface, natural diamonds are rare, brilliant, and complex. Since ancient times, mined diamonds have symbolized luxury and love. Generations have been drawn to their beauty and meaning.

However, Moissanite is becoming a popular, cheaper and greener diamond alternative. More celebrities and influencers are wearing Moissanite jewelry with their diamond collections due to its popularity and ability to pass as diamonds to the normal public. 

This cultural shift towards alternative gemstones is compatible with a more significant premium market trend toward accessibility and sustainability. 

Moissanite is challenging natural diamonds as a growing industry trend, revolutionizing the fine jewelry sector and highlighting consumer preferences. In this paper, we analyze the moissanite vs natural diamond debate.

Composition and Origin: Moissanite vs Natural Diamond

Composition and Origin: Moissanite vs Natural Diamond


French chemist Dr. Henri Moissan discovered Moissanite, a rare silicon carbide (SiC) crystal, in Canyon Diablo-meteorite crater rock samples. 

After being mistaken for diamonds, Moissan discovered their chemical makeup after 11 years. Moissanite, unlike diamonds, has a celestial origin because of this meteoric impact. 

Since natural Moissanite was uncommon, scientists began synthesizing it. Lab-grown Moissanite is generated as single crystals using a precise thermal method, ensuring purity and quality. 

Due to a lack of natural Moissanite, most wedding bands, earrings, and rings are created synthetically. Lab creation emphasizes Moissanite's unique chemical composition and attractiveness as a diamond alternative when comparing Moissanite vs Diamond.

Natural Diamonds

The Earth's mantle, 150-200 km below the surface, produces natural diamonds at tremendous temperatures and pressures.

Most diamonds are generated in dense, older continental lithospheric mantle rocks like websterite, eclogite, and peridotite. 

Diamonds form because these host rocks are mostly garnet, olivine, orthopyroxene, and clinopyroxene. Carbon atoms in these rocks align and link under intense heat and pressure over millions to billions of years, forming diamond crystals. 

Diamonds travel closer to Earth through volcanic eruptions, often related to kimberlite pipelines. These extraordinary eruptions occur when deep-buried gas expands and rises, carrying diamonds and other materials. 

Erosion and geological processes reveal diamonds to the surface, making mining an effective means to find and collect them. The geological origins of natural diamonds add to their brilliance, exclusivity, and eternal appeal.

Appearance and Optical Properties: Moissanite vs Natural Diamond


Known for its exceptional fire and brilliance, Moissanite frequently has more luminosity than natural diamonds. 

It is more durable and detailed than cubic zirconia, although some people like a duller sheen, especially on more significant jewelry pieces. Under some lighting situations, Moissanite can appear slightly yellow or gray, but it also creates vivid color bursts that resemble a "disco-ball" look. 

Due to its double refractive qualities, Moissanite has a high brightness with a refractive index ranging from 2.65 to 2.69 and a dispersion value of 0.104. 

Moissanite’s unique cut intensifies the sparkle, and its dispersion value—more than twice that of diamonds—creates a display similar to a rainbow in contrast to the whiter light that diamonds reflect. 

Natural Diamonds

Diamonds are renowned for their mesmerizing brilliance and sparkle, characterized by their captivating light within the stone. 

Brilliance, the term used to describe the white light reflected by diamonds, differentiates exceptional stones with a radiant brightness from those appearing dull with noticeable dark areas. 

A diamond's brilliance is heavily influenced by its cut quality, as superior cuts enhance its ability to refract light. 

Additionally, diamonds exhibit three distinct optical features contributing to their charisma: brightness, characterized by white light reflections; fire manifested as flashes of vibrant color; and scintillation, the interplay between areas of light and dark within the stone. 

In the Moissanite vs Diamond debate, diamonds have an RI of 2.42 which is less than that of moissanite. 

These unique optical properties collectively contribute to diamonds' breathtaking beauty and enchanting allure, making them highly coveted gemstones in the jewelry world.

Durability and Hardness: Moissanite vs Natural Diamonds

Durability and Hardness: Moissanite vs Natural Diamonds


Moissanite has an incredible Mohs hardness of 9.25, slightly less than diamonds, making it the second-toughest gemstone in terms of durability and scratch resistance. 

Because of their extraordinary resilience, jewelry pieces such as pendants, rings, and bracelets can be worn regularly without worrying about breaking, chipping, or wearing down. 

Moreover, because of its lower porosity, Moissanite has better resistance to dirt and keeps its shine without the need of constant washing. 

Due to the silicon carbide (SiC) content, the crystal has a hardness similar to that of a diamond, which guarantees durability even in enormous sizes and carat weights. 

Because of its remarkable 9.25 Mohs scale rating, Moissanite is more durable than other gemstones despite its substantial size. This makes it a popular choice for high-end jewelry pieces.

Natural Diamonds

Diamonds have an unmatched Mohs scale hardness of 10, making them one of the most complex materials on the planet. 

A diamond's remarkable endurance and resistance to wear & tear are highlighted because nothing can damage it except another diamond. 

Fancy-colored diamonds, like blue, yellow or even red diamonds, are equally resilient and have the same hardness and durability. 

Diamonds are highly resistant to chipping, scratches, and fracture because of their exceptional hardness, guaranteeing that they will maintain their beauty and worth for many generations to come. 

This unwavering toughness adds to diamonds' appeal and declares them as a smart investment.

Rarity and Availability


Thanks to modern manufacturing techniques, Moissanite, once rare in its native form, is now much more readily available. 

Modern technologies now provide high-quality colorless choices, which were previously prone to a yellow or green tint. Furthermore, the lack of natural Moissanite has prompted the creation of lab-created substitutes, guaranteeing a more readily available supply for various uses.

Because of its distinct qualities, Moissanite stands out from other gemstones. Diamonds are rated from D to Z according to color accuracy, similar to Moissanite. However, Moissanites have twice as much fire and sparkle because of their two refractive indices. 

With a high Mohs scale value, Moissanite is almost as durable as diamonds, the hardest gemstone. Because of this, Moissanite is an appealing option for anyone looking for diamond-like brilliance and durability in a more morally and environmentally responsible manner. 

Natural Diamonds

Research over 25 years confirmed the geological origins and rarity of diamonds. Rock chemistry influences fluids that eventually produce diamonds. 

These are linked to kimberlite pipes or mantle convection, which brings them up to the earth’s surface and makes these rough stones ready for mining. 

The global production of naturally mined diamonds is around 100 million carats per year. However, a significant chunk of these are blood diamonds.

Naturally mined diamonds can be found easily. But, the rarity of colorless, high-clarity natural diamonds is unequivocally high. Out of all the diamonds produced, around only 30% are suitable for jewelry; the rest are all put to industrial use.

Cost and Affordability


A 1-carat moissanite with VVS clarity is affordable and attractive. Elongated colorless moissanite stones with VVS-VS clarity allow elaborate designs. Though clarity and cut quality affect price, they are still inexpensive compared to diamonds. Fancy-colored or colorless moissanites, you name it, they will tend to be a cheaper option. On comparing Moissanite vs Natural Diamond price, a 3-carat moissanite will cost less than a 1-carat naturally mined diamond. So, if you have a tight budget, moissanite anniversary pendants, Valentine's Day bands, and engagement rings are your go-to.

Natural Diamonds

Demand, certification, size, and quality all affect the price of a diamond. Color, clarity, cut, and carat weight affect quality; rarer and better-cut diamonds fetch more incredible prices. Prices might change due to changes in demand brought on by events and trends. Because reputable organizations evaluate certified diamonds, they are more expensive. Prices are also influenced by historical relevance. All in all, diamonds are a costly option and something that everyone cannot afford. To buy a diamond, you will have to plan the purchase.

Ethical Considerations: Moissanite vs Diamonds


Among gemstones, moissanite rings and fine jewelry are unique in ethics. Because they are created in laboratories instead of mines, they avoid the substantial carbon footprint and breaches of human rights that come with diamond mining.

Natural Diamonds

It is essential to use ethical labor and diamond-sourcing techniques—the diamond industry advocates for conflict-free diamonds through programs such as the Kimberley Process. Upholding human rights and minimizing environmental effects, stakeholders embrace sustainability and fair labor standards. These initiatives uphold accountability and openness, encouraging customer trust and promoting social and environmental responsibility. 

Environmental Impact: Diamond vs Moissanite


Moissanite is a synthetic gemstone that proves to be a sustainable substitute without affecting the environment. Because of its manufacturing process, mining is unnecessary, which lowers carbon footprint and keeps the ecosystems intact. Unlike natural diamonds, Moissanite is produced ethically in laboratories and is a socially conscious option for people who believe in being ethical. It is also far away from exploitation or conflicts. 

Natural Diamonds

Significant environmental effects of diamond mining include damage to the surrounding area and water pollution. The diamond industry is adopting sustainable techniques to lessen these effects. The main goals of the initiatives are to minimize water use, restore mined areas, and lower carbon emissions. To reduce environmental damage and advance long-term sustainability, the sector supports responsible mining practices and adopts eco-friendly technologies.
