Rough Diamonds is an 8-part crime drama that follows the struggles and strife of the Wolfsons, a prominent ultra-Orthodox Jewish family within Antwerp’s world-famous diamond industry. When their youngest son takes his own life, his long-estranged brother Noah – who turned his back on his religion and made a new home within the criminal fraternity of London – returns to Antwerp and finds out that the family business is on the brink of collapse and under the heel of the local mob. While Noah desperately attempts to save the Wolfsons’ business and protect the family's legacy and honor, he and his siblings must first settle their own internal battles.
