Chemical Properties:

Both lab-grown moissanite and natural moissanite are composed of silicon carbide (SiC), where a carbon atom is surrounded by four silicon atoms arranged in a tetrahedral form. 

Physical Properties: 

Moissanite has distinctive physical properties, making it a stand-out stone among all your diamond alternative choices. This includes:


Moissanite measures 9.25 on the Mohs scale of hardness, a convenient way of identifying minerals and their scratch resistance tendencies using a rating from 1-10. A diamond measures a 10. This means moissanite is also very durable and scratch-resistant. 

Refractive Index:

Minerals are measured on the refractive index scale. The refractive index scale measures how much light passes through the stone. Moissanite has a refractive index of 2.648 -2.691 and a dispersion of 0.104 with an adamantine luster and noticeable double refractivity. This results in a stunningly brilliant and fiery stone.

Where is Moissanite Found?

Natural moissanite and lab-grown moissanite have different origins.

Natural Moissanite: Dr. Henri Moissan, the recipient of the Nobel Prize in 1893, made a significant breakthrough by uncovering natural moissanite within an Arizona meteorite crater. Such rarity contributes to the value of natural moissanite, making it very expensive.

Synthetic Moissanite: This refers to most moissanite on the market featuring budget-friendly price points available in popular shapes, various carats, and mountings.  

The Production Process of Synthetic Moissanite:

Environment: Synthetic moissanite is created in a controlled laboratory environment using a time-intensive process involving pressure and heat, requiring 2-3 months to form a single gem.

Process: The lely process is used to grow sizable silicon carbide crystals by heating pure silicon and carbon within an inert atmosphere.

Cut & Shape: The moissanite crystals are cut and faceted into popular shapes commonly associated with diamonds and other gemstones, ready to be set into fine jewelry pieces for sale.

7 Amazing Moissanite Facts You Should Know

Here are seven amazing facts you should know about moissanite. 

  1. Moissanite is Highly Ethical 

Origin: Lab-grown moissanite is unlike natural diamonds and colored gemstones because it is engineered in a lab setting, not mined from the earth, reducing the environmental impact often associated with painstaking natural gemstone extraction. 

Sustainability: The synthetic production process ensures the gem's origin and promotes sustainable practices. Synthetic moissanite does not create an unsuitable work environment with hard labor and is not associated with human rights violations and environmental damage because of its man-made origin. Moissanite is a conflict-free alternative that provides peace of mind to conscientious consumers. By choosing moissanite, individuals can feel great about selecting an ethical option without compromising quality, style, or size.

  1. Moissanite is Incredibly Durable

Scratch-Resistant: Moissanite has exceptional durability, meant to withstand the test of time. With a hardness rating of 9.25 on the Mohs scale, moissanite is second only to diamonds in terms of hardness, which rates a 10. This durability makes moissanite highly resistant to scratching, abrasion, chipping, and breaking, allowing it to maintain its glamorous appearance even with daily wear. This makes moissanite a practical choice for engagement rings, men’s rings, wedding bands, and other fine jewelry pieces.

  1. Moissanite Came From a Meteor

Moissanite came from a meteor

Straight from the galaxy far, far away, and part of your bespoke jewelry collection! Natural moissanite is exceedingly scarce, limited to minute quantities within certain geological formations like kimberlites, lamproites, and meteorites.

When meteorites containing moissanite strike the earth, it allows for discovery in small quantities within this rare impact area, initially discovered by Dr. Henry Moissan. These exciting occurrences make moissanite a fascinating and magical gemstone, bridging the limitless gap between the celestial and terrestrial realms. 

Unravel the mystery of the infinite galaxy with such a beautiful stone--reimagined in a lab and waiting for your selection. Get lost in its fire, sparkling within the meteorite crater.

  1. Moissanite is More Brilliant Than Diamonds

Moissanite possesses an impressive brilliance exceeding diamonds, lab-grown diamonds, and diamond simulants/alternatives. Moissanite's  optical properties contribute to its exceptional fire and sparkle.

The refractive index measures how light bends as it enters a gemstone, showcasing fire. Moissanite's refractive index is higher than that of diamonds. As mentioned before, moissanite has a refractive index of 2.648 -2.691, and diamond is 2.42. When compared side by side, moissanite's brilliance can be even more striking and eye-catching than that of diamonds, cubic zirconia, strontium titanate, YAG, GGG, and other diamond alternatives, natural or synthetic. This is because moissanite has an ultra-shiny disco ball or rainbow effect as the light reflects off the facets not visible in other stones. 

  1. Moissanite is Conflict-Free and Environmentally-Friendly

Synthetic moissanite is highly sought-after for its conflict-free and environmentally-friendly attributes due to its lab-grown origins. This step-b-step technological production bypasses all mining, reducing disruption of the ecosystems.  

Lab-grown moissanite isn't linked to exploitative labor practices or human rights violations due to its origin. Moissanite offers a guilt-free alternative to natural diamonds and natural colored stones associated with unethical mining.

Moissanite is Conflict Fee

Don't compromise on value and style. Choose moissanite and choose the look you have always wanted. Make a statement in eco-friendly fashion with a responsible and ethical natural diamond alternative that is glamorous, high-quality, and beautiful. 

  1. Moissanite Has Superior Heat Resistance

Moissanite is remarkable in its ability to withstand extreme temperatures that typically damage or compromise structural integrity and appearance of other gemstones. 

Unlike many other gemstones that are susceptible to damage from heat, moissanite stands strong with an impressively high melting point of 2,730 °C (4,946 °F). This heat tolerance allows moissanite to endure the intense heat generated by a jeweler's torch during activities like ring resizing or repairs. Other repairs, such as soldering and prong repair occurring in regular or unexpected jewelry maintenance will not harm moissanite when a professional jeweler with years of experience is working on your piece. 

Everlasting through accidents and hazards: Moissanite's heat tolerance may even hold up against house fires, which typically reach very high temperatures. This makes moissanite a very practical and suitable choice for an engagement ring, chain, wedding band, and more for those

seeking a high-quality investment option. 

  1. Moissanite Has Two Enchanting Nicknames

Moissanite has two captivating nicknames, adding to its alluring appeal and taking it to another level of enchantment. These monikers perfectly capture the qualities of the moissanite, making it even more attractive to those who are fans of the stone, in addition to drawing in a whole new audience. 

One of its enchanting nicknames is "The Space Diamond," inspired by the celestial origins of moissanite. Since moissanite was discovered in a meteorite crater, its connection to the cosmos gives it an otherworldly appeal reminiscent of the vastness of outer space. 

The second nickname, "The Forever Brilliance," pays tribute to moissanite's exceptional brilliance and gorgeous rainbow sparkle. This is because moissanite exhibits remarkable optical properties causing it to display an ultra-glamorous rainbow fire.

Moissanite's striking beauty captivates the eye, earning enchanting nicknames reflecting the unending fascination seen every time the light glistens on a chain or finger. By highlighting its remarkable qualities, moissanite captivates those seeking this unique stone.
