If you're considering a moissanite engagement ring and want an honest assessment before you decide, this is the guide for you. We sell moissanite — but we also wrote a guide about when you should NOT buy moissanite. Here's the complete, unvarnished picture.
The Pros of a Moissanite Engagement Ring
Exceptional durability. Moissanite scores 9.25 on the Mohs hardness scale — the second hardest gemstone used in jewelry after diamond (10). It will not scratch from daily wear, contact with surfaces, or normal activity. It is genuinely built for a lifetime of daily use. Read more: How Long Does Moissanite Last?
Extraordinary brilliance and fire. Moissanite has a higher refractive index than diamond (2.65–2.69 vs. 2.42) and more than double diamond's dispersion rate. It produces more white brilliance and more rainbow fire than diamond. Under good lighting, a moissanite ring is genuinely stunning. Read more: Does Moissanite Sparkle More Than Diamond?
Dramatically lower cost. A 1-carat moissanite costs $300–$600. A comparable diamond costs $4,000–$7,000. The savings are real and significant — money that can fund a honeymoon, a home, or simply stay in your account. Read more: Moissanite vs. Diamond: Price Per Carat Compared.
Ethical and sustainable. Moissanite is lab-created — no mining, no environmental destruction, no conflict sourcing concerns. For buyers who care about where their gemstone comes from, moissanite is the clear choice. Read more: Why Moissanite Is the Ethical Choice.
Permanent brilliance. Moissanite does not cloud, fade, or lose its optical properties over time. A moissanite ring purchased today will look identical in 30 years. Read more: What Does Moissanite Look Like After 10 Years?
GRA-certified quality. Every Moissanite Shine stone comes with a GRA certificate confirming its color, clarity, and carat weight. You know exactly what you're buying. Read more: GRA Certificate Explained.
The Cons of a Moissanite Engagement Ring
More rainbow fire than diamond. Moissanite's higher dispersion produces more rainbow sparkle than diamond. Under bright light, this is clearly visible. Some buyers love it; others find it too "disco-like" compared to diamond's more subdued white sparkle. This is the most common aesthetic objection to moissanite.

Social perception. Some people — particularly older generations — attach significant meaning to a diamond engagement ring and may react negatively to moissanite. If your partner or her family holds strong traditional views about diamonds, this is worth a conversation before you buy. Read more: How to Tell Family You Chose Moissanite.
No resale market. Moissanite has essentially no resale value. If you ever wanted to sell the ring, you would recover very little of the purchase price. This is also true of diamonds (which lose 50–70% of retail value immediately), but the diamond resale market at least exists. If resale value matters to you, this is an honest consideration.

Not a diamond. If your partner specifically wants a diamond — not a diamond alternative, not a diamond simulant, but an actual diamond — moissanite is not the right choice. Moissanite is a beautiful gemstone in its own right, but it is not a diamond. Read our honest guide: 3 Times You Should NOT Buy Moissanite.
The Bottom Line
For most buyers, the pros significantly outweigh the cons. Moissanite is a genuine, durable, beautiful gemstone that costs a fraction of diamond and performs as well or better on most optical measures. The cons are real but narrow: if you or your partner specifically want diamond's more subdued sparkle, or if traditional diamond symbolism is important to you, those are legitimate reasons to choose differently.
