Ethical Gemstones Part Three - What is Moissanite

Sharon Zimmerman

What is Moissanite and how does it compare to a diamond?

What is Moissanite?

OK, so maybe you don’t want a diamond (I’ve talked about their ethically dubious status in the past), but you’d still like some sustainable and conflict-free bling, with similar hardness and durability. And maybe you don’t have the budget for a lab-grown diamond, or you’d like to spend your money in other ways (like a hella awesome honeymoon!). What to do?. If you are happy with lab-grown stones but don’t want the expense of a lab-grown diamond, then a Moissanite is the perfect sustainable solution.

What is Moissanite?

Moissanite is silicon carbide (different than a diamond, which is carbon) and has strong covalent bonding, which is what makes it so suitable for forming into gemstones. Plus, it originates from outside the solar system, so that’s pretty cool.

So where does Moissanite come from?

Moissanite was discovered in the remnants of a meteor crash in Arizona in 1893. Originally confused with diamonds due to its brilliance and hardness, it would be more than 100 years before this stone would finally be made available for jewelry use thanks to advances in lab-growing techniques. Now all Moissanite gemstones are created in labs. This amazing stone has greater fire than a diamond and is harder than a sapphire (it reaches 9.25 on the Mohs hardness scale). The Moissanite that I get for my engagement rings comes from North Carolina’s own Charles and Colvard.

How does Moissanite hold up compared to a diamond or a lab grown diamond?

Damn fine, if you ask me. It is highly scratch resistant (it can really only be scratched by a diamond). This gemstone is brilliant, has so much fire and for much greater value. Best of all, there is no destructive mining involved with Moissanite. 

What can’t Moissanite do?

It cannot do your laundry. Trust me, I’ve tried.
