SDB, built at a cost of $388m, will challenge the dominance of Mumbai's Bharat Diamond Bourse, currently the world's largest diamond bourse and home to around 2,500 traders.

The sprawling complex boasts an incredible 659,611 m² (7.1 million sq. ft) of floor space, spanning 35 acres of land, surpassing the USA’s Pentagon as the world’s largest office building.

The bourse is made up of nine interconnected towers - each with 15 floors - emanating from a central ‘spine’. Despite its vast size, visitors can walk to any part of the bourse from the entrance in no more than seven minutes.
