Is Moissanite Worth Buying?
An honest answer from a 15‑year factory owner
Every single week, someone walks into our factory in Shenzhen and asks me: Is moissanite worth buying? I have been manufacturing jewelry for 15 years. I have overseen the cutting of thousands of moissanite stones, tested them under microscopes, and followed up with customers who wore them daily for years. This article is the honest answer I give them in person.
Most articles about moissanite come from one of two places: diamond companies that want you to keep buying diamonds at inflated prices, or moissanite sellers who exaggerate every claim to make a sale. I manufacture both moissanite and diamond jewelry in my own factory. I have zero incentive to lie. Here is what 15 years of hands‑on experience has taught me.
The Short Answer Yes, It Is.
The Verdict
Moissanite is worth buying for 90% of jewelry buyers. It delivers more visible brilliance than a diamond, costs 90% less, and is hard enough for lifetime daily wear. The only people who should choose diamond are those who need the social status of a natural diamond, those who prioritize resale value, or those who simply prefer the cooler, more subtle sparkle of a diamond.
In One Sentence
Moissanite gives you the look of a perfect diamond for a fraction of the price, with measurably better sparkle and zero ethical concerns.
Chapter 01 What Is Moissanite?
Let me clear up the biggest misconception first. Moissanite is not a diamond imitation. It is not cubic zirconia. It is not glass. Moissanite is a real gemstone with its own distinct chemical composition: silicon carbide (SiC).
It was first discovered in 1893 by a French scientist named Henri Moissan while examining rock samples from a meteor crater in Arizona. He initially mistook the crystals for diamonds. Naturally occurring moissanite is incredibly rare — almost all moissanite available today is lab‑created.
Lab‑created moissanite is chemically, optically, and physically identical to natural moissanite. The only difference is the origin. One came from a meteor impact site. The other came from a controlled laboratory environment. The final product is the same material.

Think of it this way: ice from your freezer and ice from a glacier are both H₂O. Lab moissanite and natural moissanite are both silicon carbide. Same thing, different origin.
Chapter 02 Moissanite vs Diamond
I run these tests in our factory quality‑control lab every month. GRA‑certified D‑Color VVS1 moissanite versus GIA‑certified D‑Color VS1 diamonds of the same carat weight. Here are the actual numbers.
| Property | Moissanite GRA D VVS1 |
Diamond GIA D VS1 |
Winner |
|---|---|---|---|
| Hardness (Mohs) | 9.25 | 10 | Diamond |
| Refractive Index | 2.65 – 2.69 | 2.42 | Moissanite |
| Dispersion (Fire) | 0.104 | 0.044 | Moissanite ×2.4 |
| Price / Carat | $50 – $250 | $1,000 – $18,000 | Moissanite |
| Color Grade Available | D to F (colorless) | D to Z | Moissanite |
| Clarity Grade | VVS1 to VS1 | FL to I3 | Moissanite |
| Ethical Origin | 100% lab‑created | Mined or lab | Moissanite |
| Resale Value | Low | Moderate | Diamond |
The hardness difference between 9.25 and 10 is essentially meaningless for daily wear. I have worn a moissanite wedding band daily for six years. The facets are still razor‑sharp. The stone looks exactly as it did the day I set it.
Chapter 03 Where Moissanite Beats Diamond
01 Brilliance & Fire
This is the category where moissanite does not just compete with diamond — it wins clearly. Moissanite has a refractive index of 2.65 to 2.69, compared to diamond’s 2.42. Refractive index measures how much a material bends light. More bending means more internal reflection, which means more sparkle returning to your eye.
Dispersion (commonly called “fire”) measures how much a stone splits white light into rainbow colors. Moissanite’s dispersion of 0.104 is more than double diamond’s 0.044. Under direct sunlight, spotlights, or even restaurant candlelight, a well‑cut moissanite produces visibly more colorful flashes than a diamond of identical size.
In our factory showroom, we keep both moissanite and diamond rings in the same display case. Visitors routinely pick up the moissanite first, thinking it is the more expensive piece.

02 Price
Price is where moissanite creates the most dramatic difference. Here are the actual numbers:
| Stone (1 Carat Equivalent) | Factory Wholesale | Typical Retail |
|---|---|---|
| GRA Moissanite D VVS1 | $50 – $250 | $200 – $800 |
| Lab Diamond D VVS1 | $400 – $1,200 | $2,000 – $6,000 |
| Natural Diamond D VS1 | $5,000 – $8,000 | $12,000 – $30,000 |
A factory‑direct moissanite ring in 925 sterling silver sells for around $200 to $800 retail. A comparable natural diamond ring starts at $12,000. That difference can fund an entire wedding, a honeymoon, or a down payment on a home.
03Durability
- 9.25 Mohs — harder than every gemstone except diamond
- Will not scratch, chip, or cloud over time
- Inspected after 2 years of daily wear: facet edges still razor‑sharp under 10× magnification
04Ethics
- Every moissanite is lab‑created in controlled conditions
- No mining. No conflict. No child labor.
- No environmental destruction
- Complete traceability from lab to finger
Chapter 04 Where Moissanite Falls Short
Honest, from the factory floor.
01Resale Value
- A moissanite ring resells for $50 – $150
- If resale matters, buy a branded diamond
- Think of moissanite like a car — it depreciates, but that’s because you bought it at a fair price to begin with
02Rainbow Effect
- Moissanite throws more colorful flashes than diamond
- Some love this. Some find it too flashy
- See both in person before deciding — photos do not capture the difference accurately
03Status Perception
- Diamond is a status symbol. Moissanite is not — at least, not yet
- If you want the social signal, buy a diamond. If you want a beautiful stone, buy moissanite
Chapter 05 Who Should Buy What
Choose Moissanite
- Engagement ring buyers on a budget
- Ethical consumers who refuse mined stones
- Jewelry resellers looking for healthy margins
- Second‑ring buyers wanting variety without another major investment
- Anyone who wants maximum sparkle per dollar
Choose Diamond
- Buyers who want natural diamond for family tradition
- Buyers who need resale value as a financial hedge
- Buyers who prefer the cooler, more subtle white sparkle of diamond
- Those for whom the De Beers marketing still holds emotional weight
Chapter 06 How to Buy Without Getting Cheated
- Buy GRA‑certified stones only. The certificate verifies the stone’s specifications. No certificate means no accountability — walk away.
- Choose D or E‑F color grades. D is completely colorless; E‑F is near‑colorless and indistinguishable to the naked eye. Avoid anything below G.
- Inspect cut quality. A poorly cut moissanite looks dull regardless of the raw material. Look for symmetry, proper facet alignment, and a lively sparkle pattern under any light.
- Consider the setting metal. 925 silver is fine for fashion jewelry. 18K gold or platinum is better for engagement rings worn daily for decades.
After 15 Years My Personal Take
I wear a moissanite wedding band. My wife wears a moissanite engagement ring. We made these choices intentionally — not because we could not afford diamonds, but because moissanite won on every metric that mattered to us.
A diamond is a status symbol. Moissanite is a beautiful stone.
If you want people to know you spent $20,000, buy a diamond. If you want a brilliant, ethical, durable stone that leaves you thousands for other things, buy moissanite.
Both choices are valid. Only one is honest about value.

Quick Answers Frequently Asked
Is moissanite fake?
No. Moissanite is a real gemstone with its own chemical composition: silicon carbide. It is not glass, not cubic zirconia, and not a “fake diamond.” It is a distinct, real gemstone — one that happens to have been discovered in a meteor crater.
Does moissanite lose its sparkle over time?
No. The sparkle is permanent. Unlike cubic zirconia — which clouds and dulls within months — moissanite retains its optical properties indefinitely. I have worn mine daily for six years with zero change.
Can a jeweler tell the difference?
With a diamond tester, yes — instantly. Moissanite conducts heat differently from diamond. To the naked eye, however, they look almost identical. Most jewelers will admit they cannot reliably tell them apart by sight alone.
How long does moissanite last?
Indefinitely. At 9.25 on the Mohs scale, it is practically indestructible for everyday jewelry purposes. It will not scratch from incidental contact, will not chip under normal wear, and will not degrade over decades.
Is moissanite better than cubic zirconia?
Yes — in every measurable way. Moissanite is harder (9.25 vs 8 Mohs), more brilliant (RI 2.65 vs 2.15), and will never cloud or turn milky like CZ inevitably does. CZ is a disposable costume stone; moissanite is a lifetime gemstone.
