Are you overpaying for a lab-grown diamond?
Marketed as an alternative to mined diamonds, lab-grown stones are gaining popularity among engaged couples, overshadowing the traditional dominance of mined or "natural" diamonds.
When Toronto residents Daniel Ng and Olivia Chan embarked on their ring-shopping journey in 2024, their decision to choose a lab-grown diamond was straightforward, primarily due to the significant price advantage over natural stones.
Industry experts reveal that lab-grown diamonds can be 90% less expensive than their natural counterparts.

"The tide has turned. More people are opting for lab-grown diamonds," Ng remarked.
Industry experts confirm that lab-grown diamonds are becoming more affordable and widely available, and they attribute this trend to the increasing number of young couples favoring this option. However, a Marketplace investigation uncovered a surprising reality: virtually identical lab-grown diamonds are being sold at vastly different prices, raising concerns about potential overpayment by consumers.
CBC journalists purchased two lab-grown diamonds, one from Blue Nile, a leading online jewelry retailer, and another from an Alibaba vendor. Both diamonds shared identical specifications: one carat, D-colour, ideal cut, VS1 clarity, and round shape.
The Blue Nile diamond, priced at $1,639.23 CDN, including shipping and taxes, stood in stark contrast to the Alibaba-purchased diamond, which cost a mere $228.86. Marketplace's price comparison with other online retailers revealed similar stones priced up to $1,500 before fees and taxes.
Ng expressed satisfaction with his purchase, as he proposed with a D-colour, 2.33-carat, VVS2 lab-grown diamond for less than $6,000 CDN. However, the couple was taken aback by the cost of the Alibaba diamond, admitting they were unaware of the price discrepancy.
Paul Zimnisky, a diamond industry analyst, and independent board member of Lipari Mining Ltd., acknowledged the existence of such price gaps, warning of potential "credibility problems" for the industry. He attributed the higher profit margins to jewelers' incentives to sell lab-grown diamonds, emphasizing that the selling price often reflects the wholesale cost, which can be as low as $75 to $95.
Zimnisky explained that the lab-grown diamond market operates on an economy of scale, driving down per-unit costs as production increases. He cautioned against excessive markups, suggesting that some retailers are pricing lab-grown diamonds far higher than necessary.
To verify the authenticity of the diamonds, Marketplace sent the Alibaba-purchased diamond back to the International Gemological Institute (IGI) for certificate confirmation. The certificate was legitimate, leading the journalists to consult accredited jewelry appraisers, Eddy and Allan Young, to assess the quality equivalence of the Blue Nile and Alibaba diamonds.
Upon microscopic examination, the brothers concluded that the diamonds were identical, estimating their retail value at $1,925 CDN. The variance in purchase prices did not surprise them, as Eddy Young noted that such prices are typically obtained directly from manufacturers.
Young highlighted the lack of awareness among consumers about the affordability of lab-grown diamonds, produced in manufacturing hubs like China and India. Marketplace's consultation with Greg Thompson of Gem Experts Inc. resulted in a second appraisal, valuing the diamonds at $900 retail.
Addressing the pricing inconsistencies, Marketplace questioned Blue Nile's parent company, Signet Jewelers, about the significant price difference between the Blue Nile and Alibaba diamonds, despite their similar features. Signet declined an interview but emphasized their brand's reputation, track record, and trusted quality, ensuring customer confidence.
The company also highlighted their strong sourcing standards and ethical, sustainable production processes, sourced from vendors adhering to strict annual reporting standards.
Marketplace's inquiry about pricing inconsistencies was also directed to the Canadian Jewellers Association (CJA), an industry group representing Canadian jewelers. The CJA declined an interview but stated that it does not intervene in pricing decisions, citing the impossibility of setting uniform guidelines for the industry and the lack of representation for all Canadian jewelers.
The CJA encouraged members to provide fair and impartial information for informed consumer choices.
To shop smarter, Eddy Young advised consumers to be cautious when purchasing directly from foreign manufacturers, suggesting checks for reviews, secure payment methods, and diamond appraisals for authenticity confirmation. He emphasized the increasing accessibility and affordability of lab-grown diamonds, advocating for informed choices to avoid unnecessary expenses.
Zimnisky predicts a convergence of lab-grown diamond prices towards wholesale levels. Ng and Chan, reflecting on their experience, expressed a desire for more research and consistent pricing across the industry, emphasizing the importance of informed decisions to avoid overpaying.
"I want a diamond necklace now for the wedding," Chan expressed, highlighting their intention to explore options and ask questions for future purchases. Both agreed that more consistent pricing would be beneficial for consumers.
