The near-empty Surat Diamond Bourse (SDB) is hoping the arrival of around 40 lab grown traders will signal a change in its fortunes.
The vast new center, recognized by Guinness World Records as the largest office building in existence, was officially opened last December by India’s prime minister Narendra Modi .
It has a capacity of 4,500 offices, but remains virtually empty.
The bourse has, according to local media reports, now reached an agreement with the Lab Grown Diamond Association (LGDA) to relocate around 40 lab grown companies from elsewhere in Surat.
Mahesh Gadhvi, CEO at SDB, said recently that 250 offices were currently occupied (that’s less than 6 per cent of the total).
“Steadily we are progressing towards opening more offices and starting more businesses from SDB,” he told the business news channel CNBC.
The global supply of natural diamonds has already peaked, according to Moses Madondo, CEO of De Beers Group Managed Operations. Speaking at the Joburg Indaba, a major mining and resources conference in South Africa, he explained that production is on the decline, with several mine closures on the horizon and no significant new discoveries in sight.
Madondo highlighted that this limited supply could push diamond prices higher. “Since the turn of the century, we’ve only seen one major commercial discovery, the Luele mine in Angola, where we aim to start production by the 2030s. But on a broader scale, global diamond production is set to decline,” he said. This trend, while concerning from a supply perspective, offers the potential for price growth.
In the short term, Madondo expects production to dip, but he anticipates a recovery after 2025, driven by the Luele mine ramping up and South Africa’s Venetia mine shifting to underground operations. However, the looming closure of Canada’s Diavik mine in 2026 and the shutdown of several mines in Russia will further tighten supply.
The Criminal Investigative Service (SIC) in Angola seized 710 diamonds of different carats on Sunday in Lucapa, a municipality in the northeastern Lunda-Norte province of Angola.
According to Graciano Lumanhe, the SIC spokesperson in Lunda-Norte, three individuals from Guinea Conakry were found in possession of the diamonds.

All the evidence has been submitted to the Office of the Public Prosecutor as part of the preparations for criminal proceedings against the three suspects.

Lightbox has just launched new campaigns for its lab grown diamonds – despite its announcement in June that it was halting production.
The wholly-owned De Beers-owned subsidiary says it has enough existing inventory to keep it going for the time being.
The production facility in Portland, Oregon, USA, is now being used to manufacture industrial diamonds by Element Six, also owned by De Beers.
“Lightbox has sufficient existing inventory from Element Six to meet the brand’s needs for the foreseeable future,” a company spokesperson told IDEX Online.
“At JCK (in June), we communicated that Element Six (our synthetic diamond industrial business which had also been producing LGDs for Lightbox) would suspend production of LGDs for jewellery to focus on high-tech industrial applications.
“However, Lightbox as a brand is continuing as it plays an important role in supporting the differentiation between LGDs and natural diamonds as LGD prices continue to decline and they are increasingly used in fashion jewellery.
“The latest Lightbox campaigns, referenced in the email below, reinforce this as they focus on foregrounding the message of Lightbox’s recently lowered per carat pricing and its fashion-forward approach to product design.
Lightbox says its new Fall campaigns – Shine Bright Spend Less and Modern Family – reflect the brand’s focus on fashion jewelry and accessible pricing.
Melissa Crivillaro, Lightbox’s chief marketing officer, said: “Our accessible prices, our fun and colorful innovations, and our fashion-focused lab-grown diamond jewelry collections underpin Lightbox’s broad appeal.
“As we lean into our next chapter with a revived identity, new creative campaigns and bold price messaging, we look to connect more deeply with our customers.”
The pulse of the jewelry industry and its relationship with the constantly changing world is reflected each year at Jewellery & Gem World Hong Kong (JGWHK).
This year the annual jewelry trade show attracted more than 3,300 exhibitors, a 5% decline from 2023, according to Informa Markets, which owns and operates the fair. Although final buyer numbers aren’t available, walking the floors on the first four days, it’s easy to see that foot traffic was down as well. Still the show is expected to attract about 50,000 visitors.

More important than the numbers themselves is what they represent. A major typhoon in the Shanghai area a few days before the show began meant many exhibitors and buyers from the area could not immediately make the trip to Hong Kong. Obviously, war in Ukraine and in Gaza has kept people in these regions from attending. After years of exponential growth, the U.S. jewelry market has softened, partly due to the upcoming presidential election. The China market has softened as well, reflecting the country’s overall economic challenges. These are the two largest markets in the world for jewelry. Then for the first time in memory, the fair coincided with the Mid-Autumn Festival on September 18, which further reduced overall attendance, at least temporarily.
For a fair that has been held during trade wars, citywide political protests and a once-in-a-century typhoon, these distractions were mild by comparison. Through it all JGWHK remains, by far, the largest jewelry trade fair in the world, and for good reason.
India’s exports of polished diamonds fell by 23.8 per cent year-on-year in August, according to the latest figures from the GJEPC (Gem and Jewellery Export Promotion Council).

Rough imports for the April to August period were down 22.6 per cent to $4.98bn.
Africa focused miner Gem Diamonds has found yet another big precious stone at its prolific Letšeng mine in Lesotho, the third greater than 100 carat diamond mined in September.
The 212.91 carat Type II white diamond was recovered on September 19th, the company said on Monday. It is the thirteenth diamond over 100-carat unearthed this year at the operation, it noted.
Type IIa diamonds are the most valued and collectable precious gemstones, as they contain either very little or no nitrogen atoms in their crystal structure.
The Letšeng mine, owned 70% by Gem Diamonds, is one of the world’s ten largest diamond operations by revenue. At 3,100 metres (10,000 feet) above sea level, it is also one of the world’s most elevated diamond mines.
The operation has a track record of producing large, exceptional white diamonds, which makes it the highest-dollar-per-carat kimberlite diamond mine in the world.

A flawless 16.92 carat vivid yellow diamond was unveiled last week at Jewellery & Gem World Hong Kong.
Mumbai based Venus Jewel says the radiant shaped natural diamond is one of the “most coveted diamonds” it has released in its 55 year history.
It was cut from a 28.78 carat rough stone. Natural vivid yellow colored diamonds are extremely rare. One out of approximately 10,000 carats mined is a natural fancy color diamond. Of those only a small percentage are fancy vivid, the highest grading for color saturation and brilliance.
“We are delighted to present the Yellow Lava, a true testament to our craftsmanship, energy and dynamism,” said Rajesh Shah, a partner in the company.
“The name Yellow Lava is derived from its evenly distributed vivid yellow color and flawless clarity.”
