In this post, we’ll break down what makes each gem unique and help you decide what’s right for you. So, what is moissanite? Originally discovered in a meteor crater (yes, really), moissanite is a gemstone made of silicon carbide. While today’s moissanite is lab-created, it mimics the look of a diamond with impressive clarity and fire — often sparkling even more in direct light.

How does it compare to diamonds? Here’s the quick breakdown:

• Brilliance: Moissanite has more “fire” (rainbow sparkle) than diamonds, thanks to a higher refractive index.

• Hardness: Diamonds rank a 10 on the Mohs scale; moissanite comes close at 9.25, making it durable for everyday wear.

• Price: Moissanite typically costs a fraction of a diamond — allowing for bigger looks without the steep cost.

• Ethics: Moissanite is lab-grown, making it a conflict-free and sustainable choice.

Should you choose moissanite? If you love the sparkle and want something durable, ethical, and wallet-friendly, moissanite could be your perfect match. It’s not a “fake diamond” — it’s a stunning gem in its own right.

When comparing moissanite vs diamond, the right choice depends on your budget, values, and style preferences.
