One will last forever. 1993, DTC applied for the Chinese translation of Du Fu's collection A Diamond is Eternal through Ogilvy & Mather Advertising Company in Hong Kong. After half a year's evaluation, a version of a sentence by a university teacher was selected, so the classic advertising slogan "A diamond lasts forever, and an eternity remains unchanged" successfully entered China.

"Diamonds last forever, and one lasts forever." This classic sentence refers to the brand advertising language cleverly devised by De Beers Group.

With over 120 years of diamond professional experience, De Beers Diamond Jewelry has the most professional right to speak on high-quality diamonds. De Beers Group introduced 4C standard to consumers in 1939, and skillfully came up with the world-famous brand slogan "A diamond lasts forever, and a diamond stays forever" in 1947. De Beers Diamond Jewelry Company is proud and honored to inherit this precious historical wealth.
