If you’re shopping for a forever piece an engagement ring, necklace, or pendant you’ve probably asked yourself: Should I choose moissanite or diamond?
It’s the #1 “this or that” we hear in our Phoenix studio. Both are brilliant, both are durable, and both carry their own kind of meaning. The key is figuring out which aligns with your budget, lifstyle, and values.
This guide breaks down the differences in sparkle, cost, durability, and symbolism so you can feel confident in your decision.
What’s the Real Difference?
Moissanite
- Lab-created gemstone, first discovered in a meteorite crater in 1893.
- Made of silicon carbide.
- Always lab-grown today.
Diamond
- Made of pure carbon.
- Can be mined or lab-grown.
- Graded on the famous 4Cs: cut, color, clarity, carat.
They may look alike at a glance, but their optical properties are different. The question isn’t “which is real” both are. The better question is: which feels right for you?

Step 1 · Compare the Sparkle
- Diamond: Brilliance is sharp, white, and classic. Think clean glints of light that feel timeless.
- Moissanite: Fire-heavy sparkle. That means rainbow flashes, especially in bright Arizona sun.
Neither is “better”-it depends whether you prefer the understated elegance of diamond or the lively drama of moissanite.
Quantum Qarat Tip: Visit our Custom Jewelry Gallery or Phoenix studio and compare both under natural light.
Step 2 · Think Honestly About Budget
- Moissanite: Costs a fraction of a diamond, sometimes half or less for the same visual size. That means more room in the budget for a statement setting-or the honeymoon.
- Diamonds (lab or mined): Pricier, but carry strong resale and generational value.
Neither option is “cheap.” Moissanite isn’t a knock-off; it’s its own beautiful gem. But if you’re balancing budget and brilliance, moissanite stretches your dollars further.

Step 3 · Will It Hold Up to Daily Life?
- Diamond: Ranks 10/10 on the Mohs scale. The hardest substance on Earth. Resistant to scratches, chips, and wear.
- Moissanite: Scores 9.25/10. Harder than sapphire, ruby, or emerald, but not as hard as diamond.
In plain terms? Both are daily-wear safe. If you want the absolute maximum durability for a lifetime heirloom, diamond edges ahead.
Step 4 · Consider the Meaning
- Diamond: Steeped in tradition. Generations of engagement rings, anniversary gifts, and heirlooms carry diamond symbolism. Choosing one can feel like joining a legacy.
- Moissanite: Modern, ethical, and 100% lab-grown. Choosing moissanite says, “We’re writing our own rules.”
With lab-grown diamonds, you can blend both classic diamond meaning with modern, ethical sourcing.

Why Phoenix Couples Choose Both
We see all types of shoppers in our Scottsdale and Phoenix studios:
- The couple who wanted a moissanite halo setting so they could afford a luxe wedding venue downtown.
- The heirloom-minded fiancé who upgraded grandma’s setting with a lab-grown diamond.
- The artist who wanted mixed stones moissanite in the center, diamonds on the band for something bold and personal.
Phoenix is a city of contrasts heritage meets modernity. Your stone choice can reflect that balance, too.
Caring for Moissanite vs. Diamond
- Clean weekly with mild dish soap and warm water.
- Ultrasonic cleaning (at your jeweler) works for both.
- Check prongs annually for security especially if you have a pavé band.
Moissanite may need cleaning more often since its fiery flashes can highlight oils and dirt.

FAQ: Moissanite vs. Diamond
Can you tell the difference between moissanite and diamond?
Most people can’t without magnification. Moissanite’s rainbow fire can give it away in certain lighting, but side by side, both are stunning.
Is moissanite a fake diamond?
No. Moissanite is its own gemstone, not an imitation. It’s lab-created, durable, and beautiful in its own right.
Does moissanite hold value like diamonds?
Diamonds (especially mined) traditionally have stronger resale value. Moissanite’s value is more in affordability and beauty than resale.
Are lab-grown diamonds “real”?
Yes. They are chemically, physically, and optically identical to mined diamonds and are graded by the same standards.
Which is more ethical moissanite or diamond?
Both lab-grown diamonds and moissanite are ethical, conflict-free, and eco-friendly options. Choose a reputable jeweler who is transparent about sourcing.
