Lab Grown Diamonds Vs Moissanite What’s the Difference

Lab Grown Diamonds Vs Moissanite: What’s the Difference?

In the world of engagement rings and fine jewelry, consumers are increasingly seeking alternatives to traditionally mined diamonds. Two popular contenders have emerged: lab grown diamonds and moissanite. Both offer stunning brilliance and ethical appeal, but what exactly sets them apart?

This blog post will delve into the key differences between these two gems, exploring their origins, composition, appearance, durability, and value, to help you make an informed decision for your next jewelry purchase.

What is Moissanite?

You’ve likely heard about it as a diamond alternative, and for good reason. This gemstone is stunning, with a sparkle that can match even the brightest diamonds.

Moissanite's story begins among the stars literally! It was first discovered in 1893 by a French chemist named Henri Moissan (hence the name) in a meteor crater in Arizona. Talk about an out-of-this-world origin! Initially, Moissan thought he'd stumbled upon diamonds, but further investigation revealed these sparkling crystals were something else entirely: silicon carbide.

Now, here's the thing: natural moissanite is incredibly rare. I'm talking about "finding a needle in a haystack" rare. So, the moissanite you find in jewelry today? That's the work of some clever science.

Because natural moissanite is so scarce, scientists developed a way to create it in a lab. This process involves replicating the conditions that would naturally form moissanite, resulting in beautiful, ethically sourced gemstones. Lab created moissanite has the same chemical and optical properties as its natural counterpart, so you're not missing out on any sparkle.

What are Lab Grown Diamonds?

Lab grown diamonds are diamonds created in a controlled laboratory environment using advanced technological processes that reproduce the conditions in which natural diamonds develop in Earth.

There are two primary methods for growing diamonds in a lab:

  1. High-Pressure/High-Temperature (HPHT): This method mimics the natural diamond-forming process by subjecting carbon to extremely high pressures and temperatures.
  2. Chemical Vapor Deposition (CVD): This method involves breaking down hydrocarbon gases into their atomic components and then depositing the carbon atoms onto a diamond seed, layer by layer.

The result? Diamonds that are chemically, physically, and optically identical to natural diamonds. They're not imitations—they're the real deal!

Quick Comparison Table

Environmental Impact Low Low

This table provides a snapshot, but let's dig deeper into each difference.

Detailed Comparison: Lab Grown Diamonds Vs Moissanite

These stunning gemstones are often compared, and for good reason. Both offer incredible brilliance and can be more budget-friendly than mined diamonds. But what exactly sets them apart? Let's break it down:

A. Composition and Structure:

  • Moissanite: This beauty is made of silicon carbide, a tough compound found in nature, but rarely in gem-quality sizes.  
  • Lab Grown Diamonds: As the name suggests, these are created in a lab using the same chemical composition as mined diamonds: pure carbon.  

Both have distinct crystal structures, influencing how they interact with light.

B. Appearance: Brilliance, Fire, and Luster

  • Color: Both can be colorless, but moissanite often has a slight greenish or bluish tint, while lab grown diamonds can be perfectly colorless.  
  • Visual Comparison: Moissanite tends to have a "sparklier" appearance due to its higher dispersion (more "fire"). However, some people find this "over-the-top" for everyday wear. Lab grown diamonds offer a more classic diamond sparkle.  
  • Light Refraction: This is where things get interesting! Moissanite exhibits double refraction, meaning light bends in two different directions within the stone. Diamonds, on the other hand, have single refraction. This difference can sometimes be noticeable to the trained eye.  
  • Fire: Moissanite is the undisputed champion here. Its high dispersion creates a rainbow of colors when light passes through, resulting in a dazzling "fire." Diamonds also exhibit fire, but it's generally less intense.

C. Durability and Hardness

  • Hardness: Moissanite scores a 9.25 on the Mohs scale, while diamonds reign supreme at 10. This means diamonds are slightly harder and more resistant to scratches.  
  • Everyday Wear: In real-world scenarios, both are incredibly durable for everyday wear. With proper care, both can withstand the wear and tear of daily life.

D. Price and Value

  • Price: Moissanite is generally more affordable than lab grown diamonds, especially at larger carat weights.  
  • Resale Value: Lab grown diamonds are gaining ground in resale value, but they may not appreciate as quickly as mined diamonds (which have a longer history and established market). Moissanite typically has a lower resale value.  
  • Investment Potential: If investment is your primary goal, mined diamonds might be a more traditional choice, though lab grown diamonds are gaining traction in this area.
  • Factors Affecting Price: As with any gemstone, size, cut, clarity, and color significantly influence the price of both lab grown diamonds and moissanite.  

E. Ethical and Environmental Considerations

This is a HUGE plus for both lab grown diamonds and moissanite!

  • Ethical: Lab grown diamonds eliminate the ethical concerns surrounding mined diamonds, such as potential human rights abuses and environmental damage. Moissanite, as a naturally occurring mineral, also avoids these issues.  
  • Environmental: Lab grown diamonds and moissanite have a significantly lower environmental impact than mined diamonds, which often involve extensive mining operations.  

How to Tell the Difference Between Lab Grown Diamonds and Moissanite

Let's dive into how jewelers and gemologists identify them:

The Sparkle Test

  • Moissanite's Fire: Moissanite is known for its intense, rainbow-like sparkle (what we call "fire"). It often has more colorful flashes of light than a diamond.
  • Diamond's Brilliance: Diamonds (lab grown or natural) have a unique brilliance – a mix of bright white light reflections and colorful flashes. It's a bit more subtle than Moissanite's fire.

Looking Closer

  • Magnification: Jewelers use magnification to examine the tiny details within the stone. Moissanite may have slight inclusions that are different from those in diamonds. Also, some moissanite stones might have very subtle color zoning that isn't typically seen in diamonds.
  • Cutting Style: Though less obvious to the untrained eye, the facets (the little faces cut into the stone) can be slightly different between the two.

Scientific Tests

  • Specific Gravity: This test measures the stone's density. Diamonds and moissanite have different specific gravities, so this can be a quick way to tell them apart.
  • Electrical Conductivity: There are specialized devices that measure how well a stone conducts heat. Diamonds conduct heat very efficiently, while moissanite does not. This is a reliable test used by professionals.

The Importance of Certification

When you're buying a lab grown diamond or moissanite, certification is KEY.

  • Lab Grown Diamonds: Look for grading reports from reputable labs like GIA (Gemological Institute of America) or IGI (International Gemological Institute). These reports verify that it's a lab grown diamond and provide details on its quality (color, clarity, cut, carat).
  • Moissanite: IGI also grades moissanite, providing similar information about its quality.

Pros and Cons of Each Stone

Lab grown diamonds are, chemically and physically, the same as mined diamonds. They're created in a lab environment that mimics the natural conditions under which diamonds form. This means they share the same brilliance, hardness, and durability.

Lab Grown Diamonds

Pros of Lab Grown Diamonds

  • Real Diamond, Lower Cost: You get all the sparkle and prestige of a diamond for a significantly lower price than a mined diamond of comparable size and quality.
  • Ethically Sourced: Lab grown diamonds bypass the environmental and ethical concerns sometimes associated with diamond mining. You can be confident your stone is conflict-free and hasn't harmed the planet.
  • Identical Properties: They have the same optical, chemical, and physical properties as mined diamonds. A jeweler can't tell the difference with the naked eye (and often needs specialized equipment).
  • Variety of Shapes and Sizes: Just like mined diamonds, lab grown diamonds are available in a wide range of cuts, shapes, and sizes, giving you plenty of choices.

Cons of Lab Grown Diamonds

  • Resale Value: While the resale market for lab grown diamonds is growing, it's not as established as the market for mined diamonds. You might not recoup as much of your initial investment if you decide to sell later.
  • Perception (for some): Some people still prefer the "romance" and perceived rarity of a mined diamond. However, this perception is changing rapidly as lab grown diamonds gain popularity.

Moissanite

Moissanite is a naturally occurring mineral (silicon carbide) that's now primarily lab-created for jewelry. It's known for its exceptional brilliance and fire, often even more noticeable than a diamond's.

Pros of Moissanite

  • Exceptional Brilliance and Fire: Moissanite has a higher refractive index than diamond, meaning it reflects more light and has more "fire" (colorful flashes of light).
  • High Hardness and Durability: Moissanite is very hard (9.25 on the Mohs scale, compared to diamond's 10), making it suitable for everyday wear.
  • Very Affordable: Moissanite is significantly less expensive than both mined and lab grown diamonds, making it a budget-friendly option.
  • Ethically Sourced: Since it's lab-created, moissanite is ethically sourced and avoids the ethical concerns associated with diamond mining.

Cons of Moissanite

  • Not a Diamond: Moissanite is a distinct gemstone, not a type of diamond. While it looks similar, it has different optical properties and a different chemical composition.
  • Color Variations: Some moissanite can have subtle color tints, particularly in larger stones. While colorless moissanite is available, it can sometimes be more expensive.
  • Less Prestige: While moissanite is beautiful, it doesn't carry the same cultural prestige as a diamond.

In a Nutshell:

  • Lab grown diamonds: The real deal, offering the same properties as mined diamonds at a lower cost and with ethical sourcing.
  • Moissanite: A beautiful, affordable, and durable diamond simulant known for its exceptional sparkle.

Conclusion

In the end, both lab grown diamonds and moissanite are gorgeous, ethical, and budget-friendly alternatives to mined diamonds—but they’re totally different stones. diamonds are twins to mined diamonds, with the same hardness and brilliance.

Moissanite, though, is its own thing. It has unique optical properties and gives off even more sparkle and fire than a diamond.

Choosing between the two comes down to what you’re looking for. Want something that looks just like a mined diamond? Go for a lab grown diamond. Prefer maximum sparkle and a lower price, and don’t mind a different material? Moissanite could be the perfect fit. Either way, you’ll end up with a stunning, responsible choice that you can feel good about.
