Lab Diamonds vs Mined Diamonds

Choosing the perfect diamond is more than just selecting a stone—it’s about finding a piece that tells your story. At Calvin’s Fine Jewelry, we understand that every diamond holds meaning, whether it’s a lab-grown diamond created with precision or a natural, mined diamond formed over millions of years. If you’re considering a diamond engagement ring, anniversary gift, or custom jewelry, understanding the differences between lab-grown and mined diamonds will help you make the best choice.

Are Lab Diamonds Real Diamonds?

Yes! Lab-grown diamonds are 100% real diamonds. They have the same chemical, physical, and optical properties as natural diamonds, meaning they are just as brilliant, durable, and stunning.

Unlike diamond simulants like cubic zirconia or moissanite, lab-grown diamonds are carbon-based and created using high-tech processes that replicate natural diamond formation. The two main methods are:

  • High Pressure High Temperature (HPHT) – Mimics the extreme heat and pressure found deep within the Earth.

  • Chemical Vapor Deposition (CVD) – Uses carbon-rich gas to form a diamond layer by layer.

The result? A diamond identical in structure to a mined diamond—the only difference is its origin.

Lab-Grown vs. Mined Diamonds: What’s the Difference?

1. Appearance & Sparkle

  • Do lab diamonds look the same as natural diamonds? Yes! Even professional gemologists require specialized tools to tell them apart.

  • Do lab diamonds sparkle like real diamonds? Absolutely! Both lab and mined diamonds have the same brilliance and fire—meaning they reflect light beautifully and create that signature diamond sparkle.

2. Price Comparison

  • Are lab diamonds more affordable than natural diamonds? Yes! Lab-grown diamonds typically cost 30-50% less than mined diamonds of the same size and quality. This price difference allows buyers to choose a larger, higher-quality stone within their budget.

3. Rarity & Value

  • Mined diamonds are rare and hold their value over time, making them an excellent choice for investment or heirloom jewelry.

  • Lab-grown diamonds, while stunning, do not have the same rarity or resale value since they can be produced at scale.

If you’re looking for a timeless heirloom or an investment piece, a natural diamond may be the better option. But if you want a larger diamond at a more accessible price, lab-grown diamonds offer an exceptional choice.

Do Lab Diamonds Sparkle Like Natural Diamonds?

Yes! Brilliance, fire, and scintillation—the three factors that determine a diamond’s sparkle—are the same in both lab-grown and mined diamonds. The cut quality has a bigger impact on sparkle than whether the diamond is lab-grown or natural.

Best Diamond Cuts for Maximum Brilliance:

  • Round Brilliant – The most radiant cut, maximizing light reflection.

  • Oval & Pear – Elongated shapes that enhance brilliance and appear larger.

  • Princess & Cushion – Sharp faceting creates high brilliance.

At Calvin’s Fine Jewelry, our expert team ensures that every diamond—lab-grown or natural—is perfectly cut for maximum sparkle.

Should You Choose a Lab-Grown Diamond for Your Engagement Ring?

When it comes to engagement rings, both lab-grown and mined diamonds offer stunning beauty. Your decision should be based on:

  • Budget: Lab-grown diamonds offer larger carat sizes for less.

  • Tradition: Mined diamonds have a legacy of rarity and prestige.

  • Personal Style: Both options offer endless possibilities for customization.

Popular Engagement Ring Settings for Lab & Mined Diamonds:

  • Solitaire – Timeless and elegant, placing full focus on the diamond.

  • Halo – Enhances brilliance with a surrounding frame of diamonds.

  • Three-Stone – Symbolizes the past, present, and future.

  • Hidden Halo – Adds extra sparkle in a subtle, refined way.

For those who love yellow gold engagement rings, lab diamonds pair beautifully with warm metals, creating a modern yet vintage-inspired look.
