Diamonds(1981)

Diamonds is a drama that follows Frank as he inherits Coleman and Sons, a diamond merchant business, and transforms it through ruthless tactics that alienate those closest to him. His marriage to Margaret fractures when she develops feelings for Bernard, Frank's buyer, threatening to unravel entirely. Haunted by guilt over cheating a concentration-camp survivor out of a substantial sum, Frank becomes convinced his moral transgression has cursed his life. As ambition and conscience collide, the film explores how greed corrodes relationships and whether redemption is possible when success comes at such a human cost. The tension between Frank's business acumen and his deteriorating personal world drives the narrative toward an inevitable reckoning.
