Global Diamond Market Growth

Lab grown diamonds are sold at an 80% discount on the prices of natural diamonds and are expected to become exceedingly popular in Western countries. Industrial analysis suggests that in 2023, 46% of all stones embedded in engagement rings were synthetic diamonds, which is a substantial growth of 12% from 2019. Over the forecast period, the diamond market value is expected to rise substantially, as technological advancements continue to improve the quality and size of synthetic diamonds (over 3 carats).

As open-pit resources are getting depleted while incurring high maintenance costs, major industry players are exploring different ways of the lifetimes of existing diamond mines by shifting towards underground operations. For instance, De Beers spent USD 1.0 billion on expanding its Jwaneng diamond mine in Botswana, which produces 12 million carats of diamonds. Similarly, it also expanded its South African mine of Venetia with a capital spending of USD 2.3 billion and increased its operational life up to 2045. This is creating a favourable diamond market outlook.

Increasing financial regulation is also impacting the market dynamics. In 2021, the government of Belgium mandates diamond companies to reduce cash payments to less than EUR 3,000 with the objective of combating terrorist financing and money laundering. Such regulations are expected to favourably impact the market growth in upcoming years.

Key Trends and Developments

Soaring appeal for lab-grown diamonds; evolving customer behaviour; high premiums for diamond traceability; and technological advancements are the major factors driving the diamond market growth.

December 2024

Tanishq, a jewellery retailer of the Tata Group, announced its decision to install SynthDetect XL Plus and DiamondProof machines in select stores to enable customers to authenticate the quality of their diamonds and enhance their knowledge of diamond verification. This move aligns with Tanishq’s commitment to boosting consumers’ confidence in the Indian diamond jewellery market.

November 2024

Researchers at the University of Science and Technology of China fired ultrafast laser pulses at tiny silver diamonds to create empty spaces with a density of 14.8 Tbit cm-3 for data storage within the structure. Over the forecast period, rapid technological advancements are expected to drive the adoption of diamonds as data storage units among various governments and public libraries.

November 2024

The G7 alliance and the government of Botswana established an export certification centre to reduce the cost of rough diamond imports for countries such as India. This initiative is aimed at streamlining the certification process and ensuring the ethical sourcing and authenticity of diamonds. By simplifying logistics and eliminating bureaucratic hurdles, the centre can lower import costs and enhance supply chain transparency.

June 2021

Debswana, a joint venture of De Beers and the government of Botswana, unearthed a diamond stone weighing nearly 1,098 carats and is assumed to be the world’s third largest diamond. This discovery highlights further potential for more large-scale diamond finds in the region, which can enhance export opportunities and create new avenues of investment in diamond mining operations.

Soaring appeal for lab-grown diamonds

Lab-grown diamonds are artificially developed by the process of chemical vapour deposition and undergo the same cutting, polishing, and distribution operations as natural diamonds. Their popularity can be attributed to their high degree of cost-effectiveness and resemblance to natural diamonds.

Evolving customer behaviour

Over 18%-21% of all fine jewellery transactions are expected to occur through digital channels during the forecast period. With the growth in purchasing power of Gen Z, the demand for highly personalised diamond jewellery items is expected to soar, thereby boosting the diamond market revenue.

High premiums for diamond traceability

Diamond traceability encompasses a diamond’s journey through origin to sale and can help in building consumer confidence in jewellery brands by ensuring higher transparency. Over the forecast period, upstream/midstream/downstream diamond companies are expected to increasingly prioritise their ESG goals, thereby favourably influencing the market dynamics.

Technological advancements

Industry players can use magnetic detection technologies to discover new locations for diamond mining and utilise X-ray transmission technology for finding the size of diamond stones before beginning their extraction. These companies can also use X-ray fluorescence technology for sorting diamonds and minerals differently.

Global Diamond Market Trends

Online diamond retailing

With increasing consumer comfort in shopping online, many diamond brands are gradually shifting towards digital platforms to enhance their market reach. The increasing consumer preference for convenience, the ability to compare different prices, and access to a wide range of diamonds, including customised designs of engagement rings, is surging the preference for online channels. Transparent pricing policies and virtual try-ons are enhancing the consumer appeal for online diamond retailers among younger generations, which has emerged as one of the key diamond market trends.

High premiums for diamond traceability

Diamond manufacturers are utilising digital transparency software, including blockchain, to analyse log purchasing contracts and chain of custody to better understand traceability requirements. This has enabled jewellery companies, including digital brands, to cater to the rising demand for sustainable jewellery, thereby driving the diamond market expansion. Over the forecast period, consumer ESG demands can broaden to include sustainable water use and mine safety, which highlights the need for diamond manufacturers to establish strategic partnerships with key suppliers for driving the market growth.
