Is Moissanite a Good Choice for Engagement Rings?

In recent years, moissanite has emerged as a popular alternative to diamonds—particularly for engagement rings. But is it just a trend, or a genuine option for those seeking lasting beauty, ethical sourcing, and value?

At Diamond Lab, we offer both lab grown diamonds and premium moissanite—and we’re often asked: Is moissanite actually a good choice for an engagement ring?

Let’s explore what moissanite is, how it compares to diamonds, and who it’s ideal for.

What Is Moissanite?

Moissanite is a lab-created gemstone made of silicon carbide. It was first discovered in a meteor crater in 1893 by Nobel Prize-winning chemist Henri Moissan—hence the name.

Today, all moissanite used in fine jewellery is laboratory grown, making it:

• Completely conflict-free

• Highly durable

• Sustainably produced

Moissanite is not a diamond—but it is one of the closest visual alternatives.

Moissanite vs Diamond – The Key Differences

💡 Moissanite tends to show more “rainbow fire,” while diamonds give off more white light.

Why Moissanite Makes a Good Engagement Ring Choice

✅ 1. Affordability

Moissanite offers exceptional value for money. For the same budget, you can get a much larger stone compared to a diamond—perfect for couples prioritising design or carat size.

✅ 2. Brilliant Sparkle

Thanks to its high refractive index (2.65–2.69), moissanite out-sparkles most gemstones. It’s ideal for wearers who want maximum brilliance.

✅ 3. Durability for Daily Wear

While not quite as hard as a diamond, moissanite is extremely tough and scratch-resistant. It holds up beautifully to everyday wear and doesn’t cloud or dull over time.

✅ 4. Ethical and Sustainable

Lab-created, moissanite has zero environmental destruction and no ties to conflict mining. For socially conscious couples, it’s a thoughtful alternative.

When Moissanite Might Not Be Right for You

Moissanite is not a diamond, and for some, that matters.

• It can show a warm undertone under certain lighting

• Some can spot the higher fire and “disco ball” effect, especially in brilliant cuts

• If diamond resale or tradition is important, a lab diamond may be the better fit

At Diamond Lab, we help clients see both side-by-side so they can decide what feels right visually and emotionally.

Final Verdict: Is Moissanite a Good Choice?

Yes—moissanite is a brilliant choice for many modern couples. It's durable, ethical, stunningly sparkly, and budget-friendly. Whether you're designing a custom ring or buying your first engagement piece, moissanite offers more than just affordability—it offers freedom to create without compromise.
