Kim Cương Chẳng Phải Vĩnh Hằng - Nothing Lasts Forever (2022)

Jason Kohn’s documentary, 'Nothing Lasts Forever', transcends a mere historical account of gemstones, offering instead a dazzling, incisive dissection of the true nature of value and scarcity within the diamond industry. Kohn masterfully employs his signature investigative filmmaking techniques, peeling back the layers of mystique surrounding these glittering stones, from their geological origins to the meticulous marketing strategies of De Beers that cemented the global perception of natural diamonds as eternal symbols.

Eschewing linear narrative, the film delves into compelling interviews with scientists, synthetic diamond merchants, and industry insiders, revealing the clandestine battle between mined diamonds and their laboratory-grown counterparts. The sophisticated editing, juxtaposing the perceived glamour of gems with the cold, industrial processes of creation, underscores a profound message: value is often not inherent but manufactured through artificial scarcity and societal expectation. This is a piercing analysis of modern consumerism, raising critical questions about business ethics and transparency in a multi-billion-dollar industry. 'Nothing Lasts Forever' is not just a superb investigative piece but a potent social commentary, solidifying Kohn’s reputation as a master of revealing documentaries that challenge prevailing notions of intrinsic worth and permanence.
