Love that lasts: natural diamonds continue to win hearts, with 2.1% growth in speciality jeweller sales

 

Diamonds embody enduring love, making them the natural choice for marking a relationship. In 2025, the average price of natural diamond jewellery grew by 10%, reflecting demand for the rare, precious stones. Consumers continue to value diamonds for their unique qualities, natural origins and timeless versatility as a symbol of life’s most cherished moments and enduring legacy. Valentine’s Day is expected to be sparkly this year!

Released today, 12 February 2026, by the Natural Diamond Council (NDC) in partnership with Tenoris, the Natural Diamond Trends: A 2025 Overview report uncovers U.S. consumer preferences in natural diamond jewellery. It provides an overview of 2025 that reveals the styles, qualities and buying occasions that will shape the diamond jewellery industry in the coming years. To create this report, NDC used data collated by Tenoris from over four million jewellery transactions by 2,500 speciality jewellers across the US.

The ultimate Valentine’s Gift: natural diamonds

The report found that in 2025, Valentine’s Day and Mother’s Day accounted for 16% of annual sales of natural diamonds. In 2026, natural diamonds are set to bring just as much sparkle to special occasions.

Over the next two years, the love for natural diamonds is only expected to grow. The report takes insights from the De Beers commissioned US Natural Diamond Tracker Study 2025 conducted by Ipsos, which found that more than 40% of women and 50% of men anticipated to purchase or receive natural diamond jewellery in the next 24 months.

“Together, Gen Z and Millennials now represent the majority of diamond jewellery demand globally — and they are the most influential force shaping the future of the category. With the current emphasis on personal expression and bespoke details, consumers have more ways than ever to choose a piece that reflects a shared story. In a world of replication and simulation, emotion is what makes natural diamonds irreplaceable,” says Amber Pepper, CEO of the Natural Diamond Council.

Their versatility in both subtle everyday pieces or dramatic showstoppers means they work for every style. The Pinterest Predicts 2026 report supports the view that individuality will drive demand for unique jewellery designs and vintage-inspired pieces. It highlights nostalgia and self-expression as key themes.

In 2025, the average total carat weight for jewellery sold on Valentine’s Day was 0.59 carats, with round brilliants the favourite shape and non-bridal rings the top category. Engagement jewellery also plays a meaningful role: Valentine’s Day marks the close of the US engagement season, with 47% of couples getting engaged between November and February, according to The Knot.

Engagement ring trends

For those getting engaged around Valentine’s Day, it’s likely the natural diamond will be a round brilliant in shape. They made up 62% of diamond engagement unit sales in US, according to the report.

Through 2025, an array of celebrity engagements also showcased a range of personalised settings, as well as use of fancy shapes. The likes of Selena Gomez, Taylor Swift, Georgina Rodriguez and Zendaya all revealed sparking elongated shaped diamonds for their engagement rings. The classic, elongated marquise shape saw a 12% year-on-year growth, and with many celebrity endorsements through 2025, it is likely to remain in high esteem through 2026 and beyond.

“Natural diamonds have been around for billions of years and adored by people for millennia. Formed by time. carried by nature. chosen to mark life’s most profound moments. Not only are they here to stay, but the trend is for iconic natural diamonds that will capture attention, win hearts, and help us express ourselves with authenticity,” adds Amber Pepper.

US Jeweler “Sold Lab Growns as Natural Diamonds”

A jeweler has been arrested in New Jersey, USA, over allegations that he misrepresented lab grown diamonds as natural.

Justin T. Wentzel, 43, owner of Ice Storm Jewelry, over-valued three items of diamond jewelry by as much as $23,800, according to local police.

A victim made a complaint in June and Wentzel was arrested on 7 August after he was asked to attend police headquarters.

“Mr. Wentzel was charged with theft by deception, criminal simulation, and falsifying or tampering with a record,” said Mount Olive Township Police Department, in a statement.

“Through the course of the investigation, it was determined that Mr. Wentzel sold lab grown diamonds as genuine diamonds and over valued the worth and price of the jewelry by as much as $23,800.”

Wetzel was released pending a court hearing.

Average US Engagement Ring Costs $6,750

The average price of a natural diamond engagement ring in the US last year was $6,750.

And the average size of the stone was 1.07 carats, according to a new report by the New York-based Natural Diamond Council.

It provides a detailed analysis of the shift to larger, higher quality diamonds in its downloadable 20-page Natural Diamond Trends: A 2024 Overview.

Round brilliants remain by far the most popular shapes in diamond jewelry, at 81.7 per cent, but that figure is slipping slightly. 

Among fancy shapes for all diamond jewelry, princess and cushion showed the biggest increases, albeit from a very low base (2.1 per cent and 1.0 per cent market share respectively).

The most common color for an engagement diamond was H and the most common clarity was SI1, with bridal representing 33 per cent of all natural diamond sales in the US. 

The average price of wedding sets increased 31 per cent in 2024, the report said.

“The increase was mainly due to a rise in the average size of diamonds and a notable change in the type of metal used.”

The average price of natural diamond jewelry sold across all product categories grew 2.7% to $2,360 in 2024.

The report, the latest in a series uncovering the trends, origins and impacts of natural diamonds, was jointly produced with Tenoris.

Positive Step to a $100m Natural Diamond Campaign

Key players have taken “a very important step in the right direction” to raising $100m for the long-term promotion of natural diamonds, according to Yoram Dvash, president of the World Federation of Diamond Bourses (WFDB).

He also said he was cautiously optimistic for the holiday season as prices had started to stabilize globally, inventories were reducing and De Beers and the World Diamond Council (WDC) had embarked on multimillion-dollar advertising campaigns.

Dvash (pictured) said trade bodies had reacted very positively o his call for a $100m marketing campaign after what he described as a “brainstorming session” at the Dubai Diamond Conference earlier this month.

The Antwerp World Diamond Council (AWDC) and India’s Gem & Jewellery Export Promotion Council (GJEPC), had agreed to start looking into funding campaigns by the Natural Diamond Council, he said, in collaboration with the WFDB, IDMA (International Diamond Manufacturers Association) and CIBJO (World Jewellery Confederation). More trade bodies are expected to follow suit.

Dvash said he’d called for the industry to unite behind a major and sustained marketing campaign over the next five years to create demand for natural diamonds some weeks ago, and had been pleased by their response.

“It seems that we have found the golden formula that would enable the industry to raise $100m for generic advertising of natural diamonds,” he said.

Earlier this month he said there hadn’t been a major generic marketing campaign for natural diamonds for almost 20 years, when De Beers halted its “A Diamond is Forever” promotion.

“An entire generation of consumers has come of age without having been exposed to promotional campaigns with positive messages about natural diamonds,” he said in a letter to all the WFDB’s 29 member bourses.

WFDB Call for Five-Year Marketing Campaign

The natural diamond industry needs coordinated and consistent marketing campaigns to counter declining demand, says Yoram Dvash, president of the World Federation of Diamond Bourses (WFDB).

In an open letter he calls on every member of the industry to help create a five-year plan, rather than relying on “short-term initiatives when the situation is particularly dire”.

He acknowledges that De Beers and the Natural Diamond Council are both spending millions of dollars on campaigns with leading retailers, but says it’s not enough.

“I am concerned that this is too little and too late,” he says. “To be successful, campaigns need to be coordinated and to be consistent throughout the year.”

He says there hasn’t been a major generic marketing campaign for natural diamonds for almost 20 years, when De Beers halted its “A Diamond is Forever” promotion.

“An entire generation of consumers has come of age without having been exposed to promotional campaigns with positive messages about natural diamonds,” he says in a letter to all the WFDB’s 29 member bourses.
