Lab Grown Diamonds: Frequently Asked Questions
What Are Lab Grown Diamonds?
Lab grown diamonds are real diamonds created in high-tech labs that mimic the natural conditions of diamond formation. They are chemically, physically, and optically identical to mined diamonds—just grown above ground instead of below.
Are Lab Diamonds Real Diamonds?
Yes. Lab diamonds are not fakes or imitations. They are genuine diamonds, not to be confused with simulants like moissanite or cubic zirconia.
How Are They Made?
There are two main methods:
- HPHT (High Pressure High Temperature) – replicates Earth’s natural diamond-growing environment.
- CVD (Chemical Vapor Deposition) – uses carbon gas to build diamonds atom by atom.
Do They Look Different from Natural Diamonds?
Not at all. Lab diamonds have the same sparkle, fire, and brilliance. Even gemologists need special tools to tell them apart.
Are Lab Diamonds More Affordable?
Yes! Lab grown diamonds typically cost 30–50% less than mined diamonds of the same quality. That means a bigger, brighter stone for your budget.
Are They Eco-Friendly?
Compared to traditional mining, lab diamonds are less disruptive to the environment and often more ethically produced. Some labs even use renewable energy. Ask your jeweler for sustainability credentials.
Do They Come With Certification?
Absolutely. Lab diamonds can be certified by IGI, and GCAL—the same institutes that grade natural diamonds. Certification includes the 4Cs: Cut, Color, Clarity, and Carat.
Will They Hold Their Value?
Lab diamonds don’t appreciate in value like rare mined diamonds and usually have lower resale prices. They’re a great choice for value and beauty, not investment.
Are Colored Lab Diamonds Available?
Yes! Lab grown diamonds are available in stunning fancy colors like pink, yellow, blue, and more—at a fraction of the cost of natural colored diamonds.
Are They Durable Enough for Engagement Rings?
Definitely. Lab diamonds are just as hard and durable as natural ones—10/10 on the Mohs scale—making them ideal for engagement rings, wedding bands, and daily wear.
What is the three-month rule for a ring?
The “three-month rule” suggests spending the equivalent of three month’s salary on an engagement ring. However, this is largely considered an outdated marketing concept, rather than a practical guideline. This suggestion originated from advertising campaigns and does not reflect the diverse financial realities of today’s modern couples.
How much should an engagement ring cost in Canada?
The average cost of an engagement ring varies significantly, due to factors such as the size and quality (including the “clarity”) of the diamond, the metal of the band, the complexity of the design, and the jeweler’s fees. While there isn’t a fixed cost, industry reports often indicate an average spending range from $3,000 to $5,000 or higher.
