Over the past several years, a quiet revolution has been taking place in the world of fine jewellery. Canadians, known for being thoughtful, values-driven consumers, are increasingly turning to lab-grown diamonds — not as a compromise, but as a deliberate, informed choice. Sales of lab-grown diamonds have surged across the country, and the reasons go far beyond price.
At Jacob Mercari, we've seen this shift firsthand. More couples than ever are walking through our process with lab-grown stones at the centre of their vision and they arrive educated, curious, and excited. So what's driving this movement? Let's break it down.
1. Lab-Grown Diamonds Are Real Diamonds
This is the most important thing to understand: a lab-grown diamond is not a diamond simulant. It is not cubic zirconia or moissanite. A lab-grown diamond is chemically, physically, and optically identical to a mined diamond — composed of pure carbon atoms arranged in the same crystal structure.
The difference is origin. Natural diamonds form over billions of years under extreme heat and pressure deep within the earth. Lab-grown diamonds replicate that same process in a controlled environment, using one of two methods:
• High Pressure High Temperature (HPHT) — which mimics the conditions deep within the earth's mantle
• Chemical Vapour Deposition (CVD) — which grows diamonds layer by layer from a carbon-rich gas
Both methods produce diamonds that are graded by the same gemological laboratories — IGI, GIA, and GCAL — using the same 4Cs framework: cut, colour, clarity, and carat weight. When you choose a lab-grown diamond, you're choosing a real diamond.
2. Ethical Sourcing Matters to Canadian Buyers
Canada has long been a country with strong values around environmental responsibility and ethical supply chains. It's no surprise, then, that concerns about the origins of mined diamonds resonate deeply with Canadian consumers.
Despite the implementation of the Kimberley Process in the early 2000s — an international certification scheme designed to prevent conflict diamonds from entering the market — questions about traceability, environmental disruption, and labour conditions in diamond-mining regions persist.
Lab-grown diamonds offer a verifiable alternative. Because they are produced in controlled facilities, buyers know exactly where their stone came from. For couples who want their engagement ring to reflect their values — not just their aesthetics — this peace of mind is meaningful.
3. Significantly More Diamond for Your Budget
Let's talk about one of the most compelling practical reasons: value. Lab-grown diamonds typically cost 50–80% less than comparable mined diamonds. That's not a minor discount — it's a transformative difference in what your budget can achieve.
Consider a couple with a $10,000 ring budget. With a mined diamond, they might comfortably achieve a 1.00ct stone in a good colour and clarity range. With a lab-grown diamond of comparable quality, that same budget could easily yield a 2.00–2.50ct stone — with room left for a more elaborate setting or higher cut quality.
This shift in purchasing power is significant. It allows couples to prioritize the 4Cs they care most about — whether that's size, brilliance, or exceptional clarity — without stretching their finances. In a country where the cost of living continues to rise, particularly in cities like Toronto, Vancouver, and Calgary, the value proposition of lab-grown diamonds is hard to ignore.
4. Graded and Certified to the Same Standard
One of the early hesitations around lab-grown diamonds was around quality assurance. That concern has become largely obsolete. Today, lab-grown diamonds are graded by leading international laboratories using the same rigorous standards applied to mined stones.
The three most trusted certifications for lab-grown diamonds are:
• IGI (International Gemological Institute) — the most widely used grading body for lab-grown diamonds globally, offering detailed reports on all 4Cs
• GIA (Gemological Institute of America) — one of the most respected names in gemology, now issuing grading reports for lab-grown diamonds
• GCAL (Gem Certification & Assurance Lab) — known for its precise light performance analysis and zero-tolerance grading approach
At Jacob Mercari, we work exclusively with certified stones and walk every client through their diamond's report in detail. When you purchase a lab-grown diamond from us, you know exactly what you're getting — documented and verified.
5. The Quality Has Never Been Better
Early lab-grown diamonds sometimes exhibited subtle graining or colour inconsistencies. Technological advancements over the last decade have essentially eliminated these issues. Today's lab-grown diamonds — particularly those grown using CVD technology — routinely achieve excellent colour grades (D–F) and high clarity grades (VS1–VVS2) at scale.
The result is that many lab-grown diamonds on the market today are, objectively, stunning. When set in a well-crafted ring, the visual difference between a high-quality lab-grown diamond and a high-quality mined diamond is imperceptible to the naked eye — and often to trained gemologists without equipment.
6. A Growing Acceptance Among Jewellers and the Industry
The cultural conversation around lab-grown diamonds has shifted dramatically. What was once met with scepticism from traditional jewellers is now broadly accepted — and increasingly embraced — across the industry.
Major jewellers, diamond brands, and industry bodies have all expanded their lab-grown offerings. Certification by GIA — historically associated almost exclusively with natural diamonds — was extended to lab-grown stones, lending institutional credibility to the category.
This normalization matters. Couples who choose lab-grown diamonds today are not choosing a fringe alternative — they are participating in a mainstream, well-supported segment of the jewellery market.
Is a Lab-Grown Diamond Right for You?
The honest answer is: it depends on what matters most to you.
If the geological rarity and natural origin of a mined diamond hold personal significance — if you want a stone that formed in the earth over billions of years — that is a completely valid and beautiful reason to choose natural. We work with exceptional natural diamonds at Jacob Mercari, and we would never steer a client away from what resonates with them.
But if you are drawn to the idea of a larger, higher-quality stone, a traceable origin, and a more accessible price point — without sacrificing any visual or physical quality — then a lab-grown diamond deserves serious consideration.
The best engagement ring is the one that feels right for your relationship, your values, and your vision. Our job is to help you find it.
