Are you being ripped off when buying a lab-grown diamond? It's a question many couples are now asking themselves, as these increasingly popular gems promise a more ethical and affordable alternative to mined diamonds. But here's where it gets controversial: a recent CBC Marketplace investigation revealed that the price of virtually identical lab-grown diamonds can vary wildly. Are some retailers taking advantage of consumers? Let's dive in.
Missed some important consumer news this week? Don't worry! CBC Marketplace has you covered with a roundup of the key stories you need to know.
Lab-Grown Diamonds: Are You Overpaying?
Lab-grown diamonds are gaining serious traction, especially among engaged couples. They're marketed as an ethical and budget-friendly alternative to mined diamonds, challenging the traditional dominance of "natural" stones. For example, when Toronto residents Daniel Ng and Olivia Chan were shopping for a ring in 2024, the decision to go with a lab-grown diamond was a no-brainer, primarily because of the significant cost savings. Experts estimate that a lab-grown diamond can be up to 90% cheaper than a mined diamond with similar characteristics.
"The tide has shifted. Like, more people are going with… the lab-grown," Ng explained.
Industry insiders confirm that lab-grown diamonds are becoming more affordable to produce and more readily available, contributing to their growing popularity among younger couples. But this is the part most people miss: a Marketplace investigation uncovered a startling disparity in prices for seemingly identical lab-grown diamonds, raising serious questions about whether consumers are being overcharged.
To investigate, CBC journalists purchased two lab-grown diamonds. One came from Blue Nile, a leading online jewelry retailer, and the other from a vendor on Alibaba.com, the online marketplace. Both diamonds boasted the same specifications: one carat, D-color, ideal cut, VS1 clarity, and a round shape. The Blue Nile diamond cost $1,639.23 Canadian, including shipping and taxes. Shockingly, the diamond from Alibaba cost only $228.86, all-in. Marketplace also checked prices at other online retailers and found comparable stones listed for as high as $1,500 before fees and taxes. That's quite a difference!
Marketplace reached out to Signet Jewelers, Blue Nile's parent company, to understand why their diamond was so much more expensive than the Alibaba diamond, given their nearly identical features. Signet declined an interview but issued a statement saying that "customers consistently buy Blue Nile because of the brand’s reputation, proven track record and trusted quality. Our customers have confidence knowing they are buying a product backed by experience and trust." They also emphasized their "strong sourcing standards as well as ethical and sustainable production and procurement processes," adding that the diamonds sold by Blue Nile come from vendors "who are held to strict annual reporting standards." Is brand reputation worth such a significant price increase? This is where opinions can strongly differ.

Government Documents Suggest Ottawa Stalled Airline Fee Meant to Fund Passenger Complaints System
Internal government documents obtained by CBC's Go Public suggest that Transport Canada officials and successive transport ministers worked to delay – and potentially undermine – an effort to force airlines to help pay for Canada’s air passenger complaints system. This is a critical issue for anyone who's ever faced flight delays, lost luggage, or denied boarding.
The records reveal that Transport Canada, under two different transport ministers, repeatedly intervened in the work of the Canadian Transportation Agency (CTA), which is supposed to operate independently. Parliament directed the CTA in 2023 to introduce a cost-recovery fee on airlines. But more than 2½ years later, the fee remains non-existent. As a result, taxpayers continue to foot the bill, covering roughly $30 million annually to process air passenger complaints. The backlog of people seeking compensation has ballooned to over 88,000.
Passengers denied compensation for issues like flight delays can file complaints with the CTA. To alleviate the overwhelmed system and recover part of the cost, Parliament mandated that the CTA charge airlines a fee for cases involving passengers with eligible claims. To understand the delay, Go Public filed an access to information request with the CTA, covering the period from Aug. 1, 2024, to May 20, 2025. The resulting 2,000+ pages of documents included correspondence between the CTA and transport ministers, internal discussions, and submissions from a public consultation process.
Gábor Lukács, founder of Air Passenger Rights, reviewed the documents. "What I am seeing here is strong evidence of ministerial interference with the CTA's work, which is supposed to be independent," he stated. Neither the CTA, the transport minister, nor Transport Canada agreed to interviews. Transport Canada provided a general statement that didn't address specific questions. Former transport ministers in office since the CTA was directed to implement a fee did not respond to our questions. Were airlines being unfairly protected? That is the question many are asking.

How Does AI Influence Prices When You're Shopping Online? Experts Say It's Hard to Know
Ever feel like the price of something you're looking at online changes right before your eyes? You're not imagining things. Ruby Szpeflicki, an accounting clerk, spends hours each month shopping online, seeking out deals. She's noticed a growing trend of prices shifting rapidly.
"The prices change daily," she said. "It drives me nuts. I hate it." This phenomenon is known as dynamic pricing. Algorithms track your online activity – every like on Facebook, every recipe search, every website visit – and adjust prices based on your personal information. Mark Daley, Western University's chief AI officer, confirms that this has been happening for years. However, the integration of AI has the potential to transform data gathering, granting companies access to even more personal information faster and enabling them to further influence pricing. And this is a point of concern for many.
The problem? No one knows the extent of personalized pricing through AI. David Dunbar, a lawyer formerly with the Competition Bureau, describes it as operating inside a "black box." "AI itself is so dynamic, and we're just discovering what it can do. Even the people who understand it are learning it and becoming better at understanding it and seeing what it can do." Are we sacrificing our privacy for the sake of convenience? It's a question worth pondering.
