The Diamond Bourse refers to a marketplace or exchange where diamonds are bought, sold, and traded. These are often highly specialized institutions that facilitate the trading of rough and polished diamonds between dealers. One of the most well-known diamond bourses is the International Diamond Exchange in Antwerp, Belgium, which has been a key global diamond trading center for years. There are other bourses around the world too, like the Israel Diamond Exchange and the Dubai Diamond Exchange. These institutions typically operate in secure environments and follow strict regulations to ensure the integrity of the trade. Dealers, brokers, and even manufacturers might be members of these exchanges.
