Key Takeaways

Global jewelry market: ~$280B (2023), projected ~$330B by 2028. India processes ~90% of world diamonds by volume. Italy leads fine gold jewelry (~$6.4B, ~8,200 factories). China largest producer (~$80B). Thailand dominates gemstone-set jewelry. ASM employs 10-15M miners. LGDs now ~21% of diamond market. Blockchain traceability emerging as key supply chain technology.

The global jewelry supply chain is a web connecting mines in Africa, Australia, and Russia to cutting centers in India and Israel, manufacturing hubs in China and Thailand, trading centers in Hong Kong and Dubai, and retail markets worldwide. At each node, value is added and margin is captured.

The chain begins with extraction. Gold comes primarily from mines in China, Australia, and Russia. Diamonds come from Russia (Alrosa), Botswana (Debswana), Canada, and Angola. Colored gemstones come from dozens of countries — ruby from Myanmar and Mozambique, sapphire from Sri Lanka and Madagascar, emerald from Colombia and Zambia. Silver is primarily a byproduct of copper, lead, and zinc mining.

From extraction, materials flow to processing centers. Rough diamonds go to Surat, India, where an estimated 90 percent of the world's diamonds are cut and polished by volume. Gold goes to refineries producing investment-grade bars and industrial granules. Colored gemstones go to cutting centers: Jaipur for emerald, Chanthaburi for ruby and sapphire, Guangzhou for jade.

Manufacturing concentrates in a handful of locations. Shenzhen processes 70 percent of China's gold jewelry output. Panyu handles about 30 percent of global jewelry processing volume. Meilong is the silver capital. Bangkok dominates colored gemstone jewelry. Mumbai and Surat are centers for diamond jewelry. Valenza produces Europe's highest-end luxury pieces.

Trading and logistics connect manufacturing to retail. Hong Kong, Dubai, and Antwerp are the major trading hubs. Hong Kong's duty-free status makes it the preferred entry point for diamonds and gemstones entering Asia. Dubai serves the Middle East and increasingly Africa.

At the retail end, the market is bifurcating. Traditional retail is under pressure from e-commerce and DTC brands. Lab-grown diamonds have captured over 50 percent of the US engagement ring market by unit volume. Sustainability and ethical sourcing concerns are driving demand for traceability and certification at every link in the chain.
