Major Canadian cities emerge as key markets as jewellers respond to rising demand for transparency, certification, and value
CANADA — September 2026 — The Canadian engagement ring market is undergoing a significant shift, with lab-grown diamonds moving from a niche request to a mainstream first choice for couples across the country. Industry observers point to a combination of pricing, generational buying habits, and demand for supply-chain transparency as the primary drivers behind the trend.
Key Market Drivers
Generational demand for transparency. Millennial and Gen Z buyers, who represent the majority of today’s engagement ring purchasers, are increasingly asking about a stone’s origin and production process before making a purchase. Because lab-grown diamonds are produced in a controlled setting rather than sourced through a mined supply chain, jewellers are able to speak directly to their origin — a point of confidence that resonates with this buyer segment.
Certification Remains Central to Buyer Trust
Industry experts note that certification is what separates a credible lab-grown diamond purchase from an unverifiable one. Leading Canadian jewellers now grade lab-grown stones using the same 4Cs standard applied to mined diamonds, backed by independent lab reports from recognized bodies such as GIA and IGI. Because buyers cannot personally test or verify a stone’s grading, the credibility of the jeweller standing behind the report has become as important as the stone itself.
Spotlight: A Jeweller Built for the Shift
Among the retailers positioning themselves around this shift is Cullen Jewellery, which has built its business exclusively around lab-grown diamonds and moissanite rather than offering them as a secondary, lower-cost option alongside mined stones. Originally established in Australia, Cullen has recently expanded into Canada, opening in Toronto with a Vancouver location reportedly on the way. The company states that its collection features carbon-neutral, conflict-free lab-grown diamonds, with rings designed in-house by its own jewellery team. All rings — engagement, wedding, and fashion — are backed by a lifetime guarantee.
Cullen’s purchasing process is designed to support buyers through a significant purchase decision, offering:
- A custom design service for building a ring from scratch, alongside ready-to-ship options
- Consultations with in-house engagement ring specialists, in person or virtually
- By-appointment showroom visits for in-person stone and setting comparisons
- A range of metal options (yellow, white, and rose gold, and platinum) and a full ring-sizing guide to support fit
Guidance for Prospective Buyers
For consumers shopping in the current market, industry guidance remains consistent:
- Request the grading report first — before discussing setting or design.
- Compare price per carat across multiple retailers, as lab-grown diamond pricing varies more widely than mined diamond pricing.
- Don’t equate lab-grown with lower quality — a well-cut lab-grown diamond is optically identical to a well-cut mined diamond, even under magnification.
Outlook
Market analysts suggest the conversation around lab-grown diamonds has moved past questions of legitimacy and is now centred on which retailers offer the transparency required to support a significant purchase. Jewellers built specifically around lab-grown offerings, such as Cullen Jewellery, are cited as examples of this more transparent model as it expands into the Canadian market.
