Have you ever wondered where moissanite comes from? Nobel Prize-winning chemist Dr. Henri Moissan discovered natural moissanite in 1893, hence the name moissanite.
Natural moissanite is very rare, typically found in kimberlites, lamproites, and meteorites, and only in extremely small quantities.
Since natural moissanite is so rare and expensive, scientists discovered a way to recreate its stunning beauty in a lab. So yes, the moissanite used in jewelry today is man-made. Moissanite production started in the 1990s with Charles & Colvard, a gemstone manufacturer/jewelry company that is the original creator of lab-grown moissanite.

Moissanite is a budget-friendly diamond alternative with a similar appearance. It costs less per carat with the same quality as graded using the 4Cs.
Minerals are rated on the Mohs scale of hardness. The Mohs scale of hardness is a convenient way to test and rate the hardness of minerals or “scratch-resistant” tendencies, using a ranking scale of 1-10. Moissanite rates 9.25, making it an extremely scratch-resistant mineral–diamond is famous for its hardness, rating 10/10.
Moissanite has a high refractive index of 2.65 to 2.69 with noticeable double refractivity and an adamantine luster. This makes the stone dense and incredibly brilliant–did you know that moissanite is the most brilliant stone in the world? Moissanite showcases a show-stopping “disco-ball” or rainbow effect with a noticeable doubling on the facet junctions when viewed under 10x magnification.
Moissanite is a lab-created gemstone, making it a sustainable and ethical selection instead of diamonds, gemstones, and other natural stones. Lab-created stones do not go through the mining process or harsh work conditions because they are synthesized in a lab. Choosing an eco-friendly, sustainable, and socially conscious alternative to a diamond will not compromise quality or beauty.

Drawbacks of Moissanite
At first glance, moissanite may look similar to a diamond. However, with its incredible fire and stunning rainbow flashes of bright color, this may seem overwhelming to others, making it remarkably different from a diamond.
Since moissanite is created in a lab, it is not a rare or precious stone. It is plentiful in quantity and quality, allowing it to be readily available at different price points. This makes moissanite less sought-after or prized.
There may be a stigma attached to man-made stones, often with the belief they are cheap and poorly made. Moissanite is a high-quality diamond alternative with many positive attributes that await discovery for those interested in obtaining knowledge about the history and background of moissanite.
Moissanite can be authenticated by a gemological lab for insurance purposes or by a jewelry professional who offers moissanite certifications. However, moissanite will have a lower resale value than diamonds, precious gemstones, and fine jewelry due to its origins.
How is Moissanite Made?
In short, moissanite is made in a laboratory by heating silicon and carbon until they crystallise into silicon carbide, which is then cut and faceted into a finished gem.
Moissanite is composed of silicon carbide (SiC), with a carbon atom surrounded by four silicon atoms in a tetrahedral form; the moissanite composition also found in rare natural stones.
Synthetic moissanite is formed under controlled conditions using a combination of pressure and heat. It can take 2-3 months to produce a gem through a long, arduous process.
The Lely process or Lely method is used to create large silicon carbide crystals. Production of silicon carbide crystals features a combination of high-purity silicon with carbon and heating the mixture in an inert atmosphere.
The moissanite production process replicates nature. Silicon carbide powder is heated until it becomes gas under controlled conditions, creating the right balance of elements and allowing the moissanite to grow over several months. It may take up to 2 months for the crystal to form.
Moissanite crystals are cut and faceted into different shapes and sizes (caratage) ready for setting. Moissanite is set into fine metals, including gold and platinum. Moissanite can be set into prong, bezel, pavé, and channel–all the settings that diamonds and other gemstones are commonly placed into, making it versatile and perfect for your next special purchase.
Why is Moissanite Unique
As mentioned above, moissanite is a very brilliant gemstone with a high refractive index. This makes the stone appeal to those who love incredible fire and sparkle. It is also very durable, rating a 9.25 on the Mohs hardness scale making it suitable for an engagement ring.
Compared to diamonds, moissanite is a more affordable option for those seeking a high-quality diamond alternative. Moissanite displays all the fire and sparkle of a diamond at a fraction of the cost. Get the size, cut, and carat you have always dreamed up without the markup.
Moissanite is an eco-friendly solution instead of an investing natural diamond because of its origin.

Moissanite is durable and lasts a lifetime, making it a sustainable stone for any fine jewelry design.
How to Care for Moissanite

It is very easy to keep your moissanite clean. Using warm soapy water is an easy-at-home method:
Add warm tap water with a few drops of dish detergent and mix.
Gently scrubbing your moissanite ring and other moissanite jewelry with a new, unused toothbrush or soft bristle brush wipes away bacteria and debris. Paying close attention to the prongs and underneath the stone is optimal for revealing its sparkle over and over.
Running cool water from the tap, washing away the debris, and soap.
Pat or air dry.
Tips for Storage & Safety:
Store your moissanite jewelry in a drawer, box, or jewelry sachet that keeps it safe from damage, dust, and getting misplaced.
Keeping moissanite jewelry away from harsh chemicals (chlorine, cleaning products), oils, makeup, lotion, and washes helps keep it clean and safe from possible damage.
