Are you shopping for a diamond engagement ring, wedding band, or a timeless piece of jewelry? If so, you may be wondering whether to choose Lab vs. Natural Diamonds. At Kurtis Jewellers in Waterloo, Ontario, we specialize in both natural and lab-created diamonds, helping our clients make informed decisions based on their budget, preferences, and values.
This guide will break down the key differences between lab vs. natural diamonds, their pros and cons, and what you should consider before making your purchase.

What Are Lab-Grown Diamonds?
Lab-grown diamonds (also called synthetic diamonds, man-made diamonds, or cultured diamonds) are created in a controlled laboratory environment using advanced technology that mimics the natural diamond formation process. These diamonds are chemically, physically, and optically identical to mined diamonds—meaning they have the same brilliance, hardness, and durability.
There are two main processes used to create lab-grown diamonds:
High-Pressure High-Temperature (HPHT): Mimics the earth’s natural diamond formation process using intense heat and pressure.
Chemical Vapor Deposition (CVD):Â Uses a carbon-rich gas mixture to grow diamond crystals layer by layer.
Diamond Fact:Â Lab-created diamonds can be produced in just a few weeks, compared to millions of years for natural diamonds!
What Are Natural Diamonds?
Natural diamonds are formed deep within the earth over millions to billions of years under extreme heat and pressure. These diamonds are mined, cut, and polished before being set into jewelry.
Many buyers choose natural diamonds because of their unique history, rarity, and long-term value. Since no two natural diamonds are exactly alike, each one carries a distinct character that appeals to collectors and romantics alike.
Lab-Grown vs. Natural Diamonds: Key Differences
Feature | Lab-Grown Diamonds | Natural Diamonds |
Origin | Created in a lab within weeks | Formed naturally over millions of years |
Composition | 100% real diamond (same chemical & physical properties) | 100% real diamond (naturally occurring) |
Price | 30-40% more affordable | Generally more expensive due to rarity |
Environmental Impact | Eco-friendly, no mining required | Mining impacts can be offset by sustainability initiatives |
Resale & Investment | Lower resale value due to controlled production | Higher long-term value as a rare, natural resource |
Certification | Certified by IGI, GIA, and other gem labs | Certified by GIA, AGS, and other reputable labs |
💡 Did you know? Lab-grown diamonds can be distinguished from natural diamonds using specialized equipment, but to the naked eye, they look identical!
Which Diamond Is Right for You?
Choosing between a lab-grown and natural diamond depends on your personal values and budget.
Choose a Lab-Grown Diamond If: You want the best value for your budget. You’re looking for an eco-conscious and ethically sourced option. You prefer a larger, high-quality diamond at a lower cost.
Choose a Natural Diamond If: You value rarity, uniqueness, and natural beauty. You see diamonds as an investment with higher resale value. You want a timeless symbol with a geological history.
