You’ve seen the fire. You love the price. But before you say "yes" to the ring, a nagging question remains in the back of your mind:

 

"Is this actually going to last?"

 

It’s a fair question. For decades, the diamond industry has spent billions marketing the idea that only a diamond is forever. This has left many couples wondering if choosing a moissanite engagement ring means sacrificing longevity for price.

 

Here is the honest truth: If you are buying high-quality silicon carbide (the material moissanite is made of) from a reputable brand like Gold Mercado, you aren't buying "costume jewelry." You are investing in a gemstone born from the stars that is chemically engineered to outlive us all.

 

Let’s separate the science from the marketing. Here are the top 5 myths about moissanite durability—and why you can wear yours every single day without fear.

 

 

 

 

Myth #1: "It Scratches Like Glass or Cubic Zirconia"

 

The Truth: Moissanite is the second-hardest gemstone on Earth.

 

Many people confuse moissanite with Cubic Zirconia (CZ), which is soft and scratches easily. Moissanite is in a completely different league. We measure gemstone durability using the Mohs Hardness Scale (1-10):

 

• Diamond: 10

 

• Moissanite: 9.25 - 9.5

 

• Sapphire / Ruby: 9

 

• Emerald: 7.5 - 8

 

• Glass / Dust: 5 - 6

 

 

What this means for you: Because moissanite ranks at a 9.25, it is harder than almost any other material you will encounter in daily life. Steel, glass, concrete, and even sapphires cannot scratch it. The only thing that can scratch a moissanite is a diamond or another moissanite. Whether you’re at the gym, gardening, or doing dishes, your Gold Mercado stone will remain scratch-free.

 

 

 

 

Myth #2: "It Will Get Cloudy and Look Milky Over Time"

 

The Truth: Moissanite is chemically stable and never changes color internally.

 

This is the most common fear we hear. Cheap stones like CZ are porous; they absorb water, oils, and lotions, eventually turning milky and dull inside.

 

Moissanite is non-porous. It cannot absorb anything. If your ring ever looks "cloudy," it is strictly a surface issue. This is often called an "oil slick"—a buildup of organic film from hand sanitizers, soaps, and lotions that sits on top of the stone.

 

The Fix: A simple scrub with warm water, mild dish soap, and a soft toothbrush (or a Sunshine cloth) will instantly remove the film and return your ring to its original, blinding sparkle. It’s not damaged; it’s just dirty!

 

 

 

Myth #3: "Heat Will Ruin the Stone"

 

The Truth: Moissanite is actually more heat-resistant than a diamond.

 

This surprises most people. Diamonds are pure carbon, which means they can actually vaporize or burn if exposed to extreme heat (like a house fire or a jeweler's torch).

 

Moissanite (Silicon Carbide) has a much higher heat tolerance. In fact, jewelers love working with it because they can cast it directly in molten gold without the stone shattering or changing color. You could accidentally leave your ring near a hair straightener or a hot stove, and it will remain perfectly intact.

 

 

 

Myth #4: "The Sparkle Will Fade Away"

 

The Truth: The "fire" is a permanent physical property, not a coating.

 

Some cheaper gemstones are coated with chemicals to make them shiny. Over time, that coating wears off.

 

Moissanite is different. Its brilliance comes from its Double Refractive Index (2.65), which is naturally higher than a diamond’s (2.42). This ability to bend light and create rainbows (fire) is intrinsic to the crystal structure of the stone. It is physically impossible for a Gold Mercado moissanite to lose its sparkle, just as it’s impossible for a diamond to stop being hard.

 

 

Myth #5: "It’s Brittle and Will Crack If I Drop It"

 

The Truth: Moissanite has excellent toughness and chip resistance.

 

In gemology, "Hardness" is resistance to scratching, while "Toughness" is resistance to breaking or chipping.

 

While no gemstone is indestructible (even a diamond can chip if hit at the exact wrong angle with a hammer), moissanite is incredibly tough. It lacks the "cleavage planes" that make some stones prone to splitting. It is significantly more durable than emeralds, opals, or aquamarines, making it one of the safest choices for an everyday engagement ring.

 

 

The Verdict: Is Moissanite "Heirloom Quality"?

 

Yes.

 

A moissanite ring purchased today will look exactly the same in 50 years. It can be passed down to your children and grandchildren just like a mined diamond.
