Diamonds are TikTok Shops best friend

TikTok Shop has already convinced users to buy everything from pickle kits to questionable supplements. Its latest obsession is considerably shinier.

Livestream auctions for loose, lab-grown diamonds are suddenly everywhere on the app, turning stones that once required an intimidating trip to a jeweler into something users can buy from bed in about 15 seconds.

The streams, largely produced by lab-grown diamond company Royale Diamonds, feel like QVC after several espressos. An auctioneer holds a stone beneath bright lights, briefly flashes its specifications or grading report, and starts a countdown that may last only 10 to 30 seconds. Bids fly across the screen while the host urges viewers to keep tapping. Then the clock runs out, a winner is announced, and the next diamond appears before anyone has time to reconsider what just happened.

Naturally, people are getting hooked.

Users across TikTok are showing off their auction finds, comparing collections, planning custom jewelry, and admitting that they keep returning to the streams, finding themselves “addicted,” despite having no particular need for another loose gemstone. In recent weeks, buyers have begun comparing notes about how they stumbled into the diamond-auction rabbit hole — and how quickly one purchase became five, 10, or several dozen.

TikTok creator Ryan Roth is one of them. After accidentally winning his first lab-grown diamond for $700, he bought another for $94 while scrolling in an Uber and soon had roughly 10 more stones on the way.

“I don’t know what to do with them or about it, but it’s addicting,” Roth said in one video. His justification for the expensive hobby? Simple: “I have adult money and free will.”

Users like Roth who have purchased from Royale Diamonds say every stone they bought came with a grading report from the International Gemological Institute, or IGI. Royale Diamonds has clearly recognized its newfound virality and is capitalizing on it. The company connected with Roth for what it called a “mega live” on Sunday, Aug. 23. The account streamed for nine hours, from 1 to 10 p.m., turning diamond sales into something closer to an all-day telethon.

Roth is hardly the biggest collector. One frequent bidder interviewed by Rolling Stone said she accumulated around 50 diamonds and other gemstones in one month. Having assembled her own sparkling collection, she compared herself to “Thanos gathering Infinity Stones.” Another woman told The Guardian that the streams had become her nightly viewing ritual. She has reportedly purchased more than 30 diamonds since discovering them in June, including pink and blue stones.

You don’t even have to bid to get invested. One 21-year-old said her family sometimes projects the livestreams onto a larger screen and watches them together, turning an online jewelry sale into appointment television. That is part of the appeal: There is always another stone coming. If one doesn’t interest you, the next might be bigger, cheaper, pinker, or shaped like the pear-cut diamond you’ve suddenly decided would make an excellent necklace.

Why are the diamonds so inexpensive?

Those prices aren’t magic. Most of the stones are lab-grown diamonds, which have essentially the same chemical and physical properties as natural diamonds but cost much less to produce. As manufacturing has expanded, prices have fallen: Smaller stones can sell for under $100, while many go for roughly $100 to $200 per carat.

That affordability has changed what buying a diamond can mean. Instead of reserving them for engagements or anniversaries, TikTok users are collecting colorful stones, planning custom jewelry, or simply enjoying their tiny piles of gems.

The loose stone, however, may be the cheapest part. One buyer reportedly spent about $500 on a 3.78-carat diamond, then another $1,100 to set it in a 14-karat gold ring.

A low price also doesn’t guarantee a bargain. TikTok requires some jewelry sellers to provide authenticity documents or test results, and its policy prohibits fraudulent, low-quality, and inaccurately described products. Still, bright lighting can conceal imperfections, and a grading report can’t fully convey how a stone will look or sparkle in person.

Before bidding, buyers should verify the report with the issuing laboratory and check the diamond’s measurements, carat weight, origin, cut, color, clarity, and treatments. The FTC also requires sellers to clearly disclose when a diamond was created in a laboratory rather than mined.

Finally, TikTok says livestream auction purchases are generally final sale. Buyers may have recourse if a stone is damaged, missing, or not as described. Realizing the next morning that you have no use for a three-carat oval diamond may not be enough.

Diamond auctions are part of TikTok Shop’s much bigger takeover

The ease with which idle scrolling can become a credit card charge is the bigger story here. Customers spent an estimated $50.3 billion globally through TikTok Shop during the first half of 2026. That was a 92 percent increase from the same period in 2025, with U.S. shoppers accounting for $11.8 billion of the total.

By July, TikTok Shop represented approximately 2 percent of U.S. online retail spending, up from 1.2 percent one year earlier, according to Consumer Edge data reported by Business Insider. For the month, spending on the platform reportedly surpassed the individual online businesses of Target, Costco, and Home Depot, though TikTok still trails far behind Amazon and Walmart.

A relatively small group of enthusiastic customers is helping fuel that growth. Shoppers who made at least 20 TikTok Shop purchases during the second quarter accounted for only 5 percent of buyers but generated around 30 percent of spending. Meanwhile, consumers over 35 were the platform’s fastest-growing age group.

The diamond craze makes it easy to understand why. TikTok hasn’t invented livestream shopping, impulse buying, or fast-talking auctioneers. It has simply squeezed all three into a personalized feed where entertainment and checkout happen on the same screen.

You don’t need to open TikTok looking for a diamond. You only need to pause long enough to watch one sparkle.
