  • Story.5A steadfast partnership
    with De Beers

    The world-famous diamond company De Beers Group is known for its catchphrase, "A Diamond Is Forever," which is said to be the most outstanding slogan of the 20th century. The distinctive relationship forged between this global company with a 130-year history and Kashikey is marked by second-generation president Hidetaka Kato interacting with successive generations of De Beers chairmen even before De Beers entered the Japanese market, with Kashikey becoming Japan's representative diamond dealer.
    After De Beers entered the Japanese market, the company participated in the development of numerous campaigns, including Sweet Ten Diamond, Diamond Line, and Trilogy, which brought recognition of their manufacturing techniques and the high quality of their jewelry, as well as the marketing power inside Japan.
    Later on, the development of Kashikey Brown Diamond beginning in 2003 achieved the creation of a new market. Kashikey's accomplishments and approach to this project were highly regarded by De Beers.
    With the debut of De Beers Forevermark in 2009, Kashikey participated from the beginning as a manufacturer. Having cultivated deep trust in Kashikey's thinking regarding the company's diamonds and branding, as well as its manufacturing of products, De Beers and Kashikey established a joint venture company in November 2021, taking a step forward towards a new era of history.
