What is Moissanite?

500,000 years ago, a meteorite struck Earth in the region we now know as Arizona. Thousands of years later, in 1893, Dr. Henri Moissan was studying its crater, and unearthed microscopic particles of brilliant, shiny matter. At the time, the Nobel Prize-winning chemist thought he’d uncovered a small deposit of diamonds. However, he soon discovered that the mysterious matter was even more rare! Moissanite is identified as silicon carbide and named in Dr. Henri Moissan’s honor. Since then, moissanite has only been discovered in meteorites and at the tops of volcanoes. Due to the scarcity of natural moissanite, you’re unlikely to find a natural moissanite with a reasonable price tag on the market for your engagement ring, but lucky for us Moissan dedicated the rest of his life trying to recreate silicon carbide in a laboratory so that we could make dazzling engagement rings using gemstones from the stars!

How is Lab-Grown Moissanite Created?

In the late 90’s lab-grown moissanite became a reality thanks to the Research Triangle in North Carolina. Using a thermal growing process, scientists were able to create silicon carbide crystals identical in structure to natural moissanite. It takes their labs two to three months to create a single gem of lab grown moissanite, due to an extremely complex and expensive process. The process is lengthy compared to other lab-grown gemstones, but we’ll take that over waiting for a meteor strike any day.

Due to its scarcity, almost all moissanite used in jewelry today is lab-grown. However, the brilliance and fire of lab-grown moissanite rivals that of natural moissanite. Trust us, our custom engagement rings like the Sara (shown above) give off quite a sparkle!

Moissanite vs. Diamond

Clear stones are popular in jewelry but especially so in engagement rings and wedding bands. It is common for lab-grown moissanites to be compared or confused with mined diamonds or lab-grown diamonds. On the surface, these dazzling stones are very similar. They both have a high refractive index, are very durable, have a high scale of hardness, and lots of brilliance and fire. The stones’ differences can be found upon closer inspection to their hardness, brilliance and chemical make-up. For an overview of each of these popular engagement ring stones, check out our blog Diamond, Lab-Grown Diamond, and Lab-Grown Moissanite: What’s the Difference?

Lab Grown Moissanite Characteristics


If you love sparkle, then consider using lab-grown moissanite in your engagement ring. Sparkle is measured by brilliance. Brilliance is relative to a stone’s refractive index, and this dazzling stone has a refractive index ranging from 2.65 to 2.69. For comparison, a diamond’s refractive index is only 2.42. Not only does lab-grown moissanite have a higher brilliance than most stones, but also it’s fire is dazzling. Light refracting off lab-grown moissanite creates a rainbow of colors and a fire that is higher than any other stone, at a dispersion of 0.104. Don’t believe us, check out the video above of the sparkle on one of our lab-grown moissanites!


Engagement rings can suffer from an active or accident prone lifestyle. Thankfully, for those that are constantly on the move, we at Abby Sparks Jewelry create engagement rings that complement your lifestyle. Lab-grown moissanite as an engagement ring choice is great since lab-grown moissanite is extremely durable. Due to the strength of the carbon bonds in silicon carbide, lab-grown moissanite is one of the hardest known substances and has a hardness score of 9.25 on the Mohs Scale of Hardness, exceeded only by diamonds. These tough gemstones are also highly resistant to heat, so rest assure that your engagement ring will be less likely to get damaged in a jewelry repair or a house fire.


Though lab-grown moissanite is considered a “colorless gemstone,” they are not completely without color. In certain lighting, a projection of colors can be seen. This is a fantastic characteristic that sets them apart from diamonds and we find that our clients love the rainbow of color their custom lab-grown moissanite engagement ring emits.


Like every jewelry-grade gemstone, lab-grown moissanite has inclusions. Though considered imperfections, these tiny inclusions are unique for each individual stone and therefore define the stone since the inclusions allow each stone to be one-of-a-kind. The inclusions in lab-grown moissanite are usually microscopic and do not affect the clarity or brilliance of the gemstone with regards to what the eye can see.

Ethics and Sustainability

If you lose sleep over the social, political, and environmental effects of gemstone extraction, rest assured that your engagement ring is ethical, eco-friendly, and sustainable when you choose a lab-grown moissanite. Because these gemstones are created in a lab using silicon and carbon, lab-grown moissanite engagement rings like The Laura (shown above) LINK have no risk of unsustainable gem mining, exploitation of human labor, and indirectly supporting conflict.


Lab-grown moissanite costs significantly less than many other stones, diamonds included. Used popularly as an alternative to diamonds, lab-grown moissanite engagement rings at Abby Sparks Jewelry typically costs about 30-50% of the price than the cost of its diamond engagement ring counterpart, making it a more budget-friendly option for popping the question. Since we make one-of-a-kind, true custom engagement rings, the exact savings using a lab-grown moissanite center is not precise due to additional design, metal type, and accent stone options. Check out our Custom Engagement Ring page to see the pricing of some of lab-grown moissanite creations.

The popularity of lab-grown moissanite is skyrocketing as consumers are becoming more conscious of value and origin of the stones in their jewelry. Diamonds have been the most common stone for engagement rings and wedding jewelry for decades but this may very well change in the future. The jewelry industry, particularly with bridal, has seen a steady increase in lab-grown moissanite sales each year, convincing those in the industry that lab-grown moissanite is a smart investment for your engagement ring and also a market option that is here to stay. We love that this sparkling gemstone is getting more recognition and look forward to making more lab-grown moissanite engagement rings like the Caroline custom engagement ring below.
