5 Factors That Will Impact the Diamond Industry in 2025
The industry is changing as it grapples with new realities around distribution, supply, and the need for consistent, effective marketing.

It’s been a turbulent five years for the diamond industry from the post-COVID boom of 2021, through the mini-cycles of “slump-recover-slump” between mid-2022 and late 2024.
So, in early 2025, there is one question everyone is asking. Where do we go from here?
National Jeweler discussed the challenges confronting the diamond industry with analysts Pranay Narvekar of Pharos Beam Consulting LLP and Paul Zimnisky, explored different perspectives presented earlier on the issue, and interviewed a few senior members of the trade in India.
Using this information, National Jeweler compiled a list of five factors that will define the diamond industry as it emerges from what could be the stormiest period it has weathered in a long, long time.
1. Greater Stability
Let’s start with the good news. The general opinion across the industry seems to be that the alarm bells may soon stop ringing.
And though midstream inventories are not yet at what can be considered “normal” levels, a degree of stability should return in the near term, perhaps as early as the second quarter of 2025.
Narvekar said, “There has been some improvement in polished sales in the U.S., and a reduction in levels of rough entering the pipeline, so midstream inventory levels have steadily been reducing.”
Zimnisky said it is a positive that the seriousness of the situation is being acknowledged and discussed.
In his February “State of the Diamond Market” report notes that, “the industry has … been proactive in curbing supply and midstream inventory levels are approaching more sustainable levels going into 2025.”

Nevertheless, diamantaires in India are still cautious.
They say that stability has been achieved due to better correlation between supply and demand.
While there will not be a return to the volatility of 2023-2024, significant growth is not immediately visible on the horizon.

“The industry will have to get used to lower volumes and values for the foreseeable future.” — Pranay Narvekar, Pharos Beam Consulting
2. Supply Will Plateau, Demand Will Grow
There has been a steady decline in rough supply to the diamond market since the highs of 2022.
Both De Beers Group and Alrosa reported significant drops sales in 2024 and have estimated that 2025 sales may sink even lower.
Zimnisky estimates that both companies are now maintaining higher rough inventory levels as compared with a year ago.
He projects that the total annual supply of rough to the industry will be in the range of 105 to 115 million carats.
Looking ahead, Narvekar projects the supply of natural rough will continue at the current levels for the next five to seven years, at least.
“Retail consumption has remained virtually stagnant for the last 15 years or so, barring the post-COVID spike,” he said, adding, “the industry will have to get used to lower volumes and values for the foreseeable future.”
3. Rough Distribution Changes, Midstream Consolidation
Consolidation and greater coordination—these are the buzzwords for the diamond supply chain going forward.
There is a growing understanding that maintaining stability across the pipeline has to be a shared responsibility.
Meanwhile, rough distribution systems will be modified as the Okavango Diamond Company, the rough diamond sales and marketing company owned by the Botswana government, gears up to sell the additional rough that will start accruing to it, per the country’s new 10-year sales agreement with De Beers, and Angola seeks to step up its sales.
It remains to be seen what shape beneficiation will take as the industry needs to strike a balance between socio-political goals and cost-effective operations.
Dubai has emerged as a strong player in distribution, but this could change following recent modifications to taxation in India designed to simplify compliance and encourage diamond miners to do business with Indian companies.
Miners may consider direct sales to manufacturers from within the Special Notified Zones, set up by the Indian government in Mumbai and Surat, more attractive.
Consolidation also has occurred in the midstream. A sizable portion of the polishing capacity in Surat has shifted to lab-grown diamonds, and the process will continue.
The share of larger players may rise, with small and mid-sized manufacturers remaining mostly in niche areas.
“Natural and lab-grown diamonds products cannot be sold side-by-side or interchangeably, as this will just continue to lead to overall price deflation.”— Paul Zimnisky, industry analyst
4. Differentiation Needed in Lab Grown
Lab-grown diamonds are here to stay. How will they impact the emerging landscape?
A November 2024 article by McKinsey & Company titled, “The Diamond Industry Is at an Inflection Point,” outlines possible scenarios for the market.
“First, lab-grown diamonds could take over the majority of the market outside niche luxury segments,” the article states.
“Second, the price of lab-grown diamonds could drop so low they effectively become fashion accessories that no longer compete with diamonds … (and) assuming consumers cannot tell the difference between natural stones and lab-grown diamonds, all diamonds could simply go out of fashion.”
Zimnisky stressed that clear differentiation is needed.
“Natural and lab-grown diamonds products cannot be sold side-by-side or interchangeably, as this will just continue to lead to overall price deflation for the larger category, which has negative consequences for the whole supply chain.”
Narvekar reiterated the warning he issued in 2022—lab grown is not a diamond business.
“It has to be marketed as a distinct product, not as a substitute for a natural or else both may be dragged down,” he said.
Zimnisky said there is room for both.
According to his calculations and estimates, “approximately 40 percent of current man-made diamond sales are incremental to the larger diamond industry, and forecasted to amount to some $7 billion in 2024, i.e., these are diamond sales that would not exist if lab-grown diamonds did not exist.”
“The overall size of the market has to grow. We need marketing to keep the ‘diamond dream’ alive.”— Pranay Narvekar, Pharos Beam Consulting
5. Bigger Budgets, Better Marketing?
Who will shoulder the burden of promoting diamonds to the public?
The emerging consensus is that the entire pipeline should become collective custodians of protecting the “diamond dream.”
On one side, De Beers, alongside its efforts under the Natural Diamond Council, initiated marketing and promotion collaborations with major retailers across key markets—the United States (Signet Jewelers), India (Tanishq), and China (Chow Tai Fook)—in 2024.
In India, this went a step further, with the miner collaborating with the Gem & Jewellery Export Promotion Council to launch the India Natural Diamond Retailer Alliance (Indra), a platform to involve small and mid-sized retailers in the effort.
On the other, a proposal floated at the Dubai Diamond Conference last year by midstream organizations including the Antwerp World Diamond Centre, the Gem & Jewellery Export Promotion Council, and the Dubai Multi Commodities Centre to expand the budget for marketing diamonds with contributions of a fixed minimal percentage on every sale of rough has been broadly welcomed.
The idea, if it gets formalized, will ensure that there will be a more consistent stream of money spent on marketing diamonds over a prolonged period of time.
Narvekar is clear that without such an increase in marketing and promotion, the future remains dim. He pointed out that the total amount the entire diamond industry spends on marketing is less than what one single company, Apple, allots to this vital facet of business.
“The overall size of the market has to grow. We need marketing to keep the ‘diamond dream’ alive,” he concluded.
