Grand Theft Auto IV and Chinatown Wars

In GTA IV, de Koch has several physical stores in Liberty City. Their logo remains identical to the GTA San Andreas rendition.

Grand Theft Auto V and Grand Theft Auto Online

In GTA V and GTA Online, the player can buy De Koch clothing accessories at Ponsonbys, but there are no dedicated De Koch stores in southern San Andreas. In GTA Online, organizations can store and sell looted De Koch jewelry. In addition, a De Koch clock can be found in many interiors, such as a traditional-style Hangar.

Man: Relationships can seem like an eternity.
Woman 1: You asshole! What were you doing with my sister in that hot tub?!
Man: Relieve the pressure.
Woman 2: Ice...
Man: Chill that bitch out... with ice.
Woman 2: Ice...
Man: A diamond lasts forever. But your relationship might not. A diamond is love. Rock hard. And frozen in time. Luckily, most women are shallow, and materialistic.
Woman 2: Ice...
Woman 1: A diamond? So you do love me!
Man: Nothing says I love you like a lump of carbon, mined by wage-slaves in Angola.
Woman 1: I don't even know what I was mad at you about. Do you want a blow job?
Man: Passion. It can be purchased. And it can be overpriced. Ice. Available and very expensive...
Woman 2: Ice...
Man: de Koch Diamonds.



  • Their name is an obvious play on "the cock".
