Lab-Grown vs. Natural Diamonds: What Truly Matters in 2025
In 2025, the choice between lab-grown vs natural diamonds shouldn’t be based on pricing alone. You should also consider value, authenticity, rarity, meaning, and what you want your jewelry to represent.
Technological advancements have made lab-grown diamonds more common, affordable, and nearly indistinguishable from mined stones. But for many, nothing compares to the rarity and emotional weight of a natural diamond.
Whether buying an engagement ring, a gift, or a legacy piece, this guide will help you navigate the differences. We’ll explore what matters most, including real diamonds vs lab diamonds, diamond symbolism, and diamond uniqueness.
What Are Natural Diamonds?
Natural diamonds have been formed beneath the Earth's surface for billions of years. Through extreme heat and pressure, carbon transforms into the sparkling stones we recognize today. Each diamond is a unique product of time and nature. So, no two are the same.
That’s why many people see real diamonds as more than just beautiful jewelry. They carry a story. A sense of wonder. A connection to the Earth’s history.
Their unmatched diamond brilliance, natural rarity, and emotional weight make them perfect for life’s most significant moments, including proposals, anniversaries, or family heirlooms. When you give a natural diamond, you’re giving something timeless. Something that can be passed down through generations.
What Are Lab-Grown Diamonds?
Lab-grown diamonds are created in a lab instead of deep within the Earth. These gems are also called synthetic diamonds, lab-created diamonds, or man-made diamonds.
They are grown using advanced methods like CVD (Chemical Vapor Deposition) or HPHT (High Pressure High Temperature). Both processes replicate the intense heat and pressure that form natural diamonds underground in a controlled lab setting.
The main difference? Their diamond origin is man-made, not mined and the cost of manufacturing has gotten very low in the last 5 years. This makes them more accessible for many buyers. In wholesale lab-diamonds are sold for $70 to $100 for 1 carat diamond. In Retail the prices range from $300-$1000 for 1 carat in Retail.
Lab-Grown vs Natural Diamonds: The Key Differences
When comparing lab-grown vs natural diamonds, looking beyond the surface is essential. Both are made of pure carbon and can sparkle beautifully. However, there are real differences that matter, especially when you're choosing a diamond for a special occasion.
Here’s a simple breakdown:
1. Appearance.
At first glance, they can look identical. Both can have high diamond clarity, a well-cut shape, and diamond sparkle. However, some gemologists argue that natural diamonds often possess more depth and fire due to their inherent imperfections.
2. Diamond resale value.
Natural diamonds tend to hold their value better when it comes to natural diamond vs lab-grown diamond resale value. While lab-grown diamonds may cost less upfront, their resale value is often lower and more unpredictable.
3. Longevity.
Both types are durable, but natural diamonds have existed for billions of years. Hence, they’ve already proven their diamond longevity. This makes them better suited for heirlooms and keepsakes.
4. Emotional and symbolic value.
A natural diamond is one of a kind, forged by time and nature. It carries meaning, legacy, and emotional weight that many people find irreplaceable.
5. Sustainability.
Lab-grown diamonds are often promoted as eco-friendly because they don’t require mining. However, they still consume a significant amount of energy. Natural diamonds, especially those mined responsibly, support communities and have ethical sourcing options.
Are Lab-Grown Diamonds Good Investment?
Recent market trends show that lab-grown diamonds are losing value fast. Their resale value has tanked since 2020. See the table below:
|
Year |
Value Gap vs. Natural Diamonds |
|
2020 |
10% cheaper |
|
2021 |
27% cheaper |
|
2022 |
30% cheaper |
|
2023 |
60% cheaper |
|
2024 |
74% cheaper |
|
2025 |
83% cheaper and still dropping |
So if you bought a lab-grown diamond in 2021 or later, it likely has lost most of its value. That makes lab-grown diamond jewelry a poor investment, while natural diamonds continue to hold their worth and may appreciate over time.

Many buyers today care about where their diamonds come from, and that’s a good thing. Both lab-grown diamonds and natural diamonds can be ethical diamonds, depending on how they’re made or mined.
Lab-grown diamonds are often seen as sustainable diamonds because they don’t require mining. But they still use a lot of energy during production.
On the other hand, many natural diamonds today are conflict-free diamonds. In other words, they are sourced through responsible practices that support local communities. Always check the diamond origin and certification before you buy. That way, you’ll know your diamond was sourced with care.
