Michael Koh was 17 when he won the Diamond of Distinction Award from De Beers International in 1988, followed by the Singapore Trade Development Board’s Young Designers Award in 1990, making him the youngest in both awards’ history. In 2004, he set up Caratell with his wife, Achillea Teng. Caratell was among the first to use uncommon, coloured stones in their designs for which Michael had ventured into inaccessible areas to obtain at source. In 2016, Michael added watch designer to his portfolio with Tefnut Sleeping Beauty for German watch manufacture Moritz Grossmann, and hasn’t looked back since.
